Existing hole transport material in perovskite solar cells has only been applied to toxic solvents such as chlorobenzene, having solubility problems. These solvents result in limitation for the practical use. Here, we studied on asymmetric alkoxy substitution to approach high efficient HTMs with increasing solubility. Amorphous nature from irregularity is one of the method to increase solubility and miscibility. We synthesized and characterize asymmetric polymer named P-2,10 and fabricate hole transport layers. The perovskite solar cells using asymmetric polymer leads to high PCE using novel solvent with additives (Li-TFSI and t-BP) |
