Variations in the time courses of the activation of fully-printable carbon-based multi-porous-layered-electrode perovskite solar cells (MPLE-PSCs) can lead to differences between the photocurrent density (Jsc) values obtained from one-sun photocurrent density-voltage (J–V) measurements and from incident-photon-to-current efficiency (IPCE) integration when using monochromic light. In the present work, the Jsc calculated from IPCE data was initially equal to half that obtained from one-sun J–V measurements. However, equivalent values were obtained when the J–V measurements were performed after 10 min of irradiation by a white light LED from the side of the device. This finding will be very important with regard to permitting accurate photovoltaic evaluation of MPLE-PSCs in the future.
