PbS Quantum dots and P3HT are promising materials for photovoltaic applications due to their absorption in the NIR and visible region, respectively. Our previous experimental work showed that doping Al to ZnO lattice (Al:ZnO) could efficiently improve the cell performance. In this article, hybrid solar cells containing of two active areas with ITO/Al:ZnO/PbS QDs/P3HT&PCBM/Ag structure were fabricated and the effect of PbS QD size on photovoltaic properties was investigated. Optimised solar cell showed maximum power conversion efficiency of 2.45 % with short-circuit current of 9.36 mA/cm2 and opencircuit voltage of 0.59 V under 1 sun illumination (AM1.5).
