Switching Silicon in Solar Cells Drops Production Costs

Switching Silicon in Solar Cells

Cutting the Costs of Solar Panels through a Change of Silicon

In the summer when it gets really hot, the first thing we think of is the air cooler but after a while, after we have properly cooled down, we think of the exorbitant bill that is going to come our way on account of the A/C. In such times getting a solar panel is the best solution. Although they do cost a lot to install, the subsequent costs are brought down. But who can shell out all that cash at the beginning? Here’s where scientists plan on bringing down per unit costs by changing out the silicon used.

Scientists at Michigan University have found that by switching out the silicon in solar cells, the costs drop by about 10% per unit manufactured. Solar energy has been in use for a while, as concerns for green- house gas emissions started to increase, solar energy became the new “in thing”. In some places the costs of using a solar panel instead of conventional forms of electricity is almost the same. But this 10% drop in costs will give solar panels another boost in the industry.

The Use of Silicon in Solar Panels: 


Silicon is the norm raw material that is used in solar panels or photovoltaic cells. They come in two forms- perfect crystals that cost more but will give you more efficiency and multicrystalline silicon that costs less but gives you less efficiency.

In both cases of silicon, the cells have to be etched to reduce sunlight reflection. This reduces efficiency as some part of the sunlight is lost. This loss of light through etching on the cells, gives the cells their bluish color.

The Alternative to such Silicon Treatments: 


The alternative is to use nano- texturing silicon with a dry etching technique. This gives you a blackish silicon surface that is much more efficient at capturing sun rays than the norm blue one.

The reason this type of silicon surface is black is that the entire surface of the cell is covered in etchings which resemble a forest of tiny needles. This is done so that what sunlight falls on the surface gets captured and does not get reflected back.

Another challenge to using this form of Silicon: 


With surface defects on the surface of the cell, normally you would have problems in conducting electricity. But scientists have discovered a method known as Atomic Layer Deposition or ALD for short. This coating minimizes the surface defects problem of conducting electricity.

The dilemma in using black Silicon: 


Using black silicon instead of the bluish ones in solar panels and then its subsequent treatment of ALD all adds to the cost of the solar panels. This is at least what scientists thought. Scientists thought that by using black solar panels instead, the cost would go up by 15 to 25%.

But on further notice, scientists seen that they could, in this case, use the lesser efficient and lesser costing multi crystalline silicon and get the same efficiency or even more than the normal silicon solar panels cutting costs altogether by 10%.

New Molecular Wires to help Shrink Your Devices

Molecular Wires
Since gadgets and the like first came out, scientists all over the world are in a race to shrink their sizes. It is not enough that you hold the device in your hand or fit it into your bag, they just have to get smaller. But smaller is not the only criterian, theses gadgets or gizmos have to perform better and with better battery life. To achieve this aim, scientists have tried making each and every component in the gizmo smaller and one such part is molecular wires.

Scientists at Tokyo institute have developed a new form of wire that not is smaller than their predecessor but is also better at conducting electricity. These new form of molecular wires are filled with organometallic ruthenium which gives it better conducting. The current forms of molecular wires are much different to the ones invented by the scientists up at Tokyo. In the sense, that these new molecular wires get their high conducting power from a different source.

Molecular Wires in Tiny Devices: 


As devices get smaller, their component parts also get smaller, that’s a no brainer. But molecular wires are just the building blocks in such devices and maybe one of the most important yet fundamental of all parts.

By carefully designing these molecules, scientists have tried to make beeter contraptions for us to use.

The New form of Molecular Wires: 


These new form of molecular wires are in the form of a metal- electrode- molecular- metal- electrode junction. This includes a polyene molecule which is an organic chain like molecule.
These new form of molecular wires are based on the engineering of the energy levels of the conducting orbitals in the wire.

Is the new form of Molecular Wires better? 

 

Scientists used scanning tunneling microscopy to understand the level of conductance in these new form of molecular wires. What they found was that these new molecular wires are better than the standard or other fully organic molecular wires.

This brought scientists to explore the origins of the superior conductivity in molecular wires. They found that the properties that gave these molecular wires their high conducting properties came from orbital splitting in the molecular wires.

This orbital splitting brings about changes in original electron orbitals in the atoms of the molecular wires to make a new hybrid orbital. This new form of orbital facilitates electron transfer between mental electrodes and molecular wires.

This finding is rare to see in current MMM junctions.

What gives these Molecular wires their Higher conductance: 


The most important factor that gives these molecular wires their higher conductivity is the narrow gap between the highest and lowest molecular orbitals. The new technique formulated by scientists in making these molecular wires exploits this knowledge in enhancing the molecular wires conductivity.

Using the same MMM junction in these molecular wires along with the extremely narrow gap between the highest and lowest orbitals, scientist have come up with a new form of molecular wires that has unprecedented levels of conductance.

Shape Detection now with Google Chrome 70 Beta

Shape Detection


So Chrome has just turned a decade old and Google celebrated by making some major updates like an almost full change of the user interface and like with all major updates- a performance improvement as well. But that’s not all that was in store for Chrome. Google also added shape detection and other features to boost security as well, like using biometrics in web based applications. But the tinkering is not over just as yet. Google recently released its beta for Chrome 70 that includes the shape detection, web authentication and some other updates as well.

Shape Detection in Chrome: 

Google uses this shape detection API to bring a device’s feature of detecting faces, barcodes and text to web pages.

Shape detection constitutes three APIs in one bundle. You have the face detection software, barcode detection API in shape detection and of course text detection API also in the shape detection API. Basically the shape detection API pretty much does as the name describes but for further information Google has given its own description of what you can expect from its shape detection API.

For face detection in the shape detection API- given the image bitmap or face or blob even, the face detection API gives you the location of that face and the eyes, nose and mouth in that face.

To gain more control over the process you can always prioritize speed over performance when it comes to search results for faces. You could even limit the number of faces given as results, using this method in shape detection.

The barcode detection API in shape detection API decodes the bar codes or QR codes for you into strings with values ranging from single sets of digits to multi line texts.

The text detection API in shape detection API is meant to read Latin- 1 text used in images.

The use of shape detection in Chrome could open up a host of useful opportunities for developers. Adding facial recognition in shape detection API could mean better security like Apple’s FaceID. Text detection too has a lot of opportunities where it can be used in.

QR or barcode reading while it will be more useful in other places, it is less useful in places like the US where QR codes or barcodes are not used much.

Web authentication on Chrome: 

To add more security Google has added Web authentication update with support for a PublicKeyCredential type. This allows web based applications to use and create strong cryptographically attested credentials for their users.

This feature was present in Chrome 67 for desktop by default and now has been activated for Chrome Android as well.

Another feature added by web authentication on Chrome is the use of finger print or biometrics. This uses the feature present on phones or the mac to give users extra security when using web based applications. That means on various websites, web operators can ask for your finger print using the scanners on your phone or mac to verify your identity.

Antennas for Extremely Fast Wireless Internet

Antenna

Wireless Internet to make Internet browsing Faster

As talks of 5G do the rounds, there is talk of much faster internet speeds and data speeds as well. For all those speeds newer connections, newer frequencies and newer tech needs to come out. Talking about one of those speeds- internet speeds, now. A new spin- off MaxWaves is set to be tested out that will give us are super- fast wireless internet. This is a new form of antenna that directs the electronic signal electronically in the right direction thereby optimizing the signal in whatever weather conditions, be it rain, sunshine or snow.

In a few years- time as people switch on to faster data such as 5G or 6G even, there is need for better tech. As data transfers increases, the amount of data rates too will increase and in 2025 is poised to increase by more than 100 times the current amount. What this means is that antennas at the current base stations will have to transmit much higher amounts of data than what they are currently doing.

Talk of New Tech: 


The new tech to increase the transmission rates of data or for extremely fast internet speeds is being developed as we speak. Researchers have developed a new form of antenna technology in which base stations can communicate electronically to wirelessly transfer internet or data between themselves.

This new form of wireless internet will allow large amounts of data to be transferred that is not currently possible. The amount of data that can be transferred will take place at never- before- seen- levels between mobile base stations. This wireless internet will give 5G and 6G networks their fast transmission speeds.

Dual Purpose of this new wireless internet: 


This wireless internet that came about by the new antenna technology will be much faster than your average day speeds and the antenna technology that goes into making this new form of wireless internet will supposedly have a dual purpose as well.

This antenna technology will allow the radio beams to change direction electronically for optimum transmission so that the dishes holding these antennas will not have to physically move to enable transmission.

Wireless Internet to Adapt to all Weather Conditions: 


This new form of wireless internet that uses new antenna technology can adapt to all types of weather ensuring the best internet speeds irrespective of the weather.

This new form of wireless internet also uses much less energy than what is consumed at present making it much more effective. The electronic control that is used in this wireless internet can be adapted to work best in wind, storm or rain.

The electronic beams that are used in this form of wireless network ensure that no cables are needed underground and the entire system can be configured using electronic means.

This means that the size of network connection can be scaled up at a short notice, temporarily, like for example at a major event.

This new feasibility study will build up on what was learnt with the first fewtests and will begin commercialization shortly.
