| Popis: | 8th World Conference on Photovoltaic Energy Conversion; 237-240 Lower performances are usually recorded for perovskite and silicon/perovskite tandem solar cells that use tin oxide (SnO2) grown by Atomic Layer Deposition as an electron selective layer instead of solution-processed SnO2. This work attempts to determine possible causes for such limitations. A comparative study on chemical, electrical, optical and topographical properties of ALD-grown SnO2 and solution-processed SnO2 thin films and on their integration in perovskite-based solar cells is presented. This study points out the SnO2/perovskite interface as the main performance-limiting element. Specifically, a larger workfunction for ALD-grown SnO2 may create a potential barrier for electron extraction at PK interface. |
