The Javey Research Group has been getting a lot of attention lately. In July 21st, UC Berkeley published a press release about the electronic skin the Javey Research Group has developed (click here to read the press release). A paper thin electronic skin with sensors that light up when you touch them and the brightness of the light depends on the pressure you apply on the skin. Even though this is very exciting news, we did not add this to our website at the time, as it’s not directly related to solar energy. However, just 3 days later, another UC Berkeley press release came out about Javey Research Group’s work in III-V Photovoltaics (click here to read the press release).

The latest press release about the Javey Research Group points to a paper, “A direct thin-film path towards low-cost large-area III-V photovoltaics”, that was recently published in Scientific Reports, Nature.com. In this paper, the team demonstrates their work to apply Vapor Liquid Solid (VLS) technique, which is commonly used to create semiconductor nano-wires, to thin films. As we mentioned in our Javey Research Group review (click here to see the review), the Javey Research Group is extremely strong in nano-technology and photovoltaics is one of the fields that benefit from their research efforts.

By using VLS, the Javey Research Group creates InP thin films on metal foils, which is a very promising step to lower the cost of III –V solar cells to make them eligible for terrestrial PV usage and not just for space missions.

It is worth mentioning that the team uses Indium as an example and this technique does not depend on such an expensive substance. To read more about the team’s work, please click on this link to download their paper.
