Organic-inorganic hybrid metal-halide perovskites are very interesting materials and can be used as an absorber in photovoltaic device. Efficiencies of solar cells based on metal halide perovskites above 20% have been reported, however, the long-term stability of related solar cells is still challenging. The robustness of triple cation perovskite films seems to indicate the way to obtain a long-term stability. The samples used on the experiments consisted on a substrate with a layer of porphyrin. Their characterization by surface photovoltage (SPV) technique was performed by analyzing its transport length in interaction with the perovskite. The procedure included the measurements before and after the perovskite layerRead More →
