We measured the charge recombination kinetics using transient photovoltage (TPV) and laser transient absorption spectroscopy (L-TAS) in MAPbI3−xClx perovskite solar cells using low band gap polymers as hole transport materials (HTMs).
Newly designed N-substituted perylene diimide based acceptor copolymers have been characterized and tested for organic solar cells with P3HT in different weight ratios.
