| Abstract [eng] |
Organic-inorganic perovskite solar cells (PSCs) have achieved a recorded power conversion efficiency (PCE) of 25.7%.[1] Thus, PSCs are considered to be the dominant player in the next-generation photovoltaic market.[2] So far, single-junction PSCs with narrow bandgap values have attracted attention.[3] As a member of perovskite materials, widebandgap perovskite (WBG-PVK) can`t be ignored because it is important for tandem solar cells due to its matchable bandgap.[4] However, low PCE and the current of WBG-PSCs limited the efficiency of the tandem solar cell. So, it is necessary to further improve the PCE of wide bandgap PSCs. Here, we demonstrate a series of SAMs with different alkyl chain lengths as interfacial modifiers to modify the PTAA and perovskite layer for improving the optoelectronic properties of PSCs by improving the quality of perovskite films and increasing the transport and extraction of interfacial carriers. The structures of the self-assembled monolayer materials (SAMs) is presented in Figure 1. [...]. |
