Surface modified fullerene electron transport layers for stable and reproducible flexible perovskite solar cells |
| 초록 |
The need for high temperature to proceed with TiO2 based electron transport layer (ETL) prevents the utility of perovskite solar cells. Recent development on other ETLs makes it possible to process in low temperature, but such ETLs cannot endure external bending, which means low flexibility. Herein, we report a low temperature processed ETL which enables the flexible planar perovskite solar cells. A poly(allylamine) (PAA; 0.08 wt%) solution was deposited on a C60 layer and heated at 150 °C for 60 s, resulting in the formation of an insoluble robust C60–PAA ETL on the flexible substrate. The flexible planar perovskite solar cell with the C60–PAA ETL exhibited excellent properties with 83% efficiency retention as well as high efficiency (15.2%) without any hysteresis after 600 cycles of bending. This kind of strategy would positively affect the photovoltaic market. |
