Efficiency limiting factors of organic bulk heterojunction solar cells identified by electrical impedance spectroscopy
The current-voltage characteristic and the performance of organic bulk-heterojunction solar cells are very sensitive to small variations in the production steps or environmental influences. In our experiments, we found a large variation of the short-circuit current, which does not correspond to the...
