The improved dye-sensitized solar cells were fabricated using TiO2-carbon nanotube nanocomposite photoanodes. An improvement of 91 % for power conversion efficiency is achieved through the incorporation of carbon nanotubes into TiO2mesoscopic film photoanodes. The further investigation indicates that enhancement of power conversion efficiency depends on the carbon nanotube content in nanocomposite photoanodes. With the carbon nanotube content increasing from 1 to 3 wt. %, the power conversion efficiency of solar cells significantly improves from 3.02 to 5.78 %. When the carbon nanotube content is up to 5 wt. %, however, its value is down to 4.24 %.

Double Electron

Zinc Oxide (ZnO) has been regarded as a promising electron transport layer (ETL) in perovskite solar cells (PSCs) owing to its high electron mobility. However, the acid-nonresistance of ZnO could destroy organic-inorganic hybrid halide perovskite such as methylammonium lead triiodide (MAPbI3) in PSCs, resulting in poor power conversion efficiency (PCE). It is demonstrated in this work that Nb2O5/ZnO films were deposited at room temperature with RF magnetron sputtering and were successfully used as double electron transport layers (DETL) in PSCs due to the energy band matching between Nb2O5 and MAPbI3 as well as ZnO. In addition, the insertion of Nb2O5 between ZnO and MAPbI3 facilitated the stability of the perovskite film. A systematic investigation of the ZnO deposition time on the PCE has been carried out. A deposition time of five minutes achieved a ZnO layer in the PSCs with the highest power conversion efficiency of up to 13.8%. This excellent photovoltaic property was caused by the excellent light absorption property of the high-quality perovskite film and a fast electron extraction at the perovskite/DETL interface.
