Abstract
- • Inorganic Cu 2 GeS 3 nanocrystals are utilized as hole transporting layer in C-PSCs. • Cu 2 GeS 3 could effectively extract photo-generated holes and suppress the charge carrier recombination. • C-PSC with a champion PCE of 19.0% is demonstrate. Hole transporting layer (HTL) is indispensable for promoting the power conversion efficiency (PCE) and device stability of perovskite solar cells (PSCs), especially for the carbon electrode based PSCs (C-PSCs). Compared with the large amount of organic HTLs, which are available for metal electrode based PSCs, the inorganic HTLs for C-PSCs are relatively scarce. In this study, we successfully synthesized Cu 2 GeS 3 nanocrystals with spherical shape and well dispersibility, and further explore their potential to function as inorganic HTL for C-PSCs. The Cu 2 GeS 3 HTL can greatly improve the PCE of C-PSCs to 19.0 %, which is enhanced by 36.3 % compared with that (PCE = 13.9 %) of HTL-free C-PSCs. The reported PCE in our study is among the highest PCEs for C-PSCs with inorganic HTL, therefore, our study indicates that Cu 2 GeS 3 nanocrystals are excellent inorganic HTL for C-PSCs.
