#Black silicon photodetector breaks the 100% efficiency limit
“#Black silicon photodetector breaks the 100% efficiency limit” UV-light triggers electron multiplication in nanostructures. Credit: Wisa Förbom Aalto University researchers have developed a black silicon photodetector that has reached above 130% efficiency. Thus, for the first time, a photovoltaic device has exceeded the 100% limit, which has earlier been considered as the theoretical maximum for…
