Summary:•The novel CdS/CuInS2/polymer planar heterojunction hybrid solar cells are designed.•The polymer absorption range and charge mobility affect remarkably the device performance.•Polymer layer acts as complementary absorber and selective extractor of holes. This study reports the fabrication of a new planar heterojunction hybrid solar cell using CuInS2/polymers (MEH-PPV, P3HT and PCE10) as the composite donor and CdS as the acceptor. The main absorber layer in planar hybrid heterojunctions is CuInS2 film, while the polymer film facilitates complementary absorption and selective hole extraction. The impact of charge mobility and absorption range of polymer film on the device performance was examined. Since PCE10 outperforms MEH-PPV and P3HT in terms of hole mobility and has superior absorption complementarity with the CuInS2 film, PCE10-based hybrid cell showed significantly improved Jsc and FF and achieved a remarkable power conversion efficiency of 5.35%.
