How a Silicon Heterojunction solar cell is made? MRS SciVid-2017 (winner)

Looking for PV-Lab (Photovoltaic Labs ) on the web I found this video which explains the process of the development of silicon (Si) solar cells. It seems interesting so I want to share it with you. The most efficient silicon solar cells in 2020 are developed using Si-heterojunctions (26.7% lab and 24.4% module) [1]. The junction is formed between the crystalline silicon (Eg = 1.12 eV ) and amorphous silicon (Eg = 1.75 eV) deposited on each face of the wafer. This difference in energy gaps gives the name heterojunction to this technology. https://youtu.be/tzQw1e0gP_4 How a silicon solar cell (2017)…

DIY Culture: Repair and reuse a smartphone

The DIY or Do It Yourself culture is a great way to fight against the programmed or built-in obsolesce. I have owned this phone for 4 years; since then I have kept it with me almost everywhere. This Technology has helped me to reduce wasted time in routine tasks like doing lines in the bank. This is my second battery replacement, two years ago I embrace the international battery replacement program of Apple. At that moment I realize that I will be able to keep my phone for one more year. This movement was incredible because I could start to…

Hub de innovación tecnológica: Eficiencia energética y Energías Renovables

Step by step, we should lead the science from the university labs to the marketplace. There will be no opportunities if you don't seek them.  Solar Semiconductors Morelos will attend this meeting looking for strategic partners inside the industry and technical collaboration with GIZ and the  Queretaro innovators.
