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). Unequivocally, we assigned both transient decays to the recombination process between photo-injected electrons at the TiO2 and the oxidised polymers.
