Effect of donor materials on the photovoltaic performance of perovskite solar cells

With the continuous reduction of non-renewable energy, people began to look for new energy as an alternative actively. Solar energy has become the focus of scholars because of the advantages of low cost, and the development was not subject to geographical restrictions. And the conversion between the photoelectric was achieved through the development of a variety of electronic devices and perovskite solar cells were concerned widely. The effect of donor materials on the photovoltaic performance of perovskite solar cells was presented in this paper. It is concluded by using the experimental data analysis that the important influence factor of the photovoltaic performance of the perovskite solar cell was the absorption property of the donor material.
