Super Flexible Transparent Conducting Oxide‐Free Organic–Inorganic Hybrid Perovskite Solar Cells with 19.01% Efficiency (Active Area = 1 cm2)

Abstract

Flexible Photovoltaic Devices In article number 2100733, Sang Hyuk Im and co-workers developed super flexible transparent conducting oxide (TCO)-free perovskite solar cells with a single-layered graphene electrode on polydimethylsiloxane substrates with excellent bending stability. By co-doping the graphene/PTAA layers with varying concentrations of Li-TFSI additives, the optoelectronic properties of the TCO-free electrode could be manipulated to optimize charge collection for highly efficient and flexible photovoltaic devices.
