German scientists have fabricated a carbon electrode perovskite solar cell with a hole-transporting bilayer made of organic semiconductors instead of a conventional hole transport layer. They claim this approach improves the device's fill factor and open-circuit voltage.Researchers in Germany have sought to improve the performance of carbon electrode perovskite solar cells through a hole-transporting bilayer made of organic semiconductors, instead of a conventional hole transport layer (HTL), which they said is able to enhance their fill factor and open-circuit voltage. They explained that replacing ...Den vollständigen Artikel lesen ...
