Recombination Kinetics

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).

It is generally presumed that the vast majority of carriers created by chemical doping of semiconducting polymer films are coulombically trapped by the counteranion, with only a small fraction that are free and responsible for the increased conductivity essential for organic electronic applications.

Ultrafast Transient Absorption Spectroscopy

Decoration of Ag-ultrathin Ni-MOF onside Cu2O was firstly fabricated. The charge-transfer dynamics at heterostructure was in-depth revealed by ultrafast transient absorption spectroscopy. NH3 yield rate (4.63 μg h-1 cm-2) with...
