Abstract

Planar hybrid heterojunction PbS-polymer solar cell is lagging behind compared with its counterparts due to limited studies. This work is aimed to understand the mechanisms of this technology and improve its performance, by tuning the quantum dot (QD) bandgap (Eg) and the modified ligand exchange and fabrication process. With planar structure of PbS QDs and PTB7-Th, relative high V_OC (>0.5 V) was obtained in device with QD Eg in the range of 1.3–2.0 eV. The highest V_OC and J_SC was recorded to be 0.645 V and of 15.5 mA/cm² respectively. And the best device performance with PCE of 4.43% (V_OC 0.561 V, J_SC 14.47 mA/cm² and FF 54.6%) was demonstrated. Which is over double the performance of previously reported similar planar hybrid PbS-organic heterojunction solar cells, due to the improved and balanced parameters after optimization.
