The lead comes from both the perovskite material and a compound used to make a component of the perovskite solar cell, known as the capping layer. Now, research by scientists from Nanyang ...
Scientists from China's Northwestern Polytechnical University have used a lithium-free doping strategy to fabricate a perovskite solar cell based on a metal-free hole transport layer (HTL ...
Perovskite solar cells are a thin, flexible technology that can even be painted onto a structure ... There are other technologies that have come up to try to do it cheaper, better, faster that have ...
