Fig. 3: Dual-irradiation photovoltaic parameters of semitransparent devices.
From: Two quasi-interfacial p-n junctions observed by a dual-irradiation system in perovskite solar cells
a Schematic drawing of a dual-irradiation testing setup; b J–V curve of devices with the Au-22.5 nm/ITO under single or dual irradiation with one or two light sources, respectively. (LED light goes in from the ITO side and 1 sun simulated light goes in from the FTO side). ETL electron-transport layer, HTM hole-transport material.
