Black silicon photodetector achieves record efficiency of above 130% – Tech Explorist
Aalto University researchers have developed a black silicon photodetector that has reached efficiency above 130% in UV range without external amplification.
At present, ultraviolet sensors are utilized in numerous fields ranging from various spectroscopy applications via biotechnical innovations to industrial process control. Despite this, the performance of current UV sensors is surprisingly poor.
Now, researchers have developed a photovoltaic device that has achieved an external quantum efficiency (EQE) of more than 130%. This record high performance was obtained using a nanostructured black silicon photodiode with the self-induced junction. This…
