Abstract
Differing from conventional technology utilizing double-layer electron transport layer (ETL) to improving power conversion efficiency of perovskite solar cell, the present invention discloses a novel electron transport structure comprising an interfacial diploe moment enhancing layer, an electron transport layer and an interfacial layer. After applying this electron transport structure in a perovskite solar cell, it is found that an interfacial dipole moment formed between the electron transport layer of the electron transport structure and an active layer of the perovskite solar cell is amplified, so as to give rise to an enhanced driving force for the separation of photogenerated carriers and accelerating charge extraction. Moreover, a variety of experimental data have proved that, compared with the perovskite solar cell having double-layer ETL, the perovskite solar cell using this novel electron transport structure exhibits understanding performances including short-circuit current, open-circuit voltage, filling factor, and power conversion efficiency.
