The organic and hydrophobic polymer poly[N, N′-bis(4-butilphenyl)-N, N′-bis(phenyl)-benzidine] (polyTPD) represents a promising hole transport layer (HTL) for perovskite photovoltaics due to its suitable energy levels, whereby its highest occupie

We tune the Fermi level alignment between the SnOx electron transport layer (ETL) and Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3 and highlight that this parameter is interlinked with current–voltage hysteresis in perovskite solar cells (PSCs). Furthe

One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high luminescence yields and pho

Understanding the role of Cesium and Rubidium additives in perovskite solar cells: trap states, charge transport, and recombination

Adding cesium (Cs) and rubidium (Rb) cations to FA(0.83)MA(0.17)Pb(I0.83Br0.17)(3) hybrid lead halide perovskites results in a remarkable improvement in solar cell performance, but the origin of the enhancement has not been fully understood yet. In t
