Abstract

A new spectral response (SR) measurement routine is proposed that is universally applicable for all perovskite devices. It is aimed at improving measurement accuracy and repeatability of SR curves and current–voltage curve spectral mismatch factor (MMF) corrections. Frequency response, effects of pr...
