Compositional engineering of perovskite materials for high-performance solar cells

Voltage output of efficient perovskite solar cells with high open-circuit voltage and fill factor

The voltage output of perovskite solar cells is found to be dependent on both the energy level of perovskite itself as a solar absorber and hole transporting materials.
