Abstract

In the present study, attempts have been made for the first time to investigate the influence of leadsulfide (PbS) colloidal QUANTUM DOTS along with their ligand exchange from long-chain insulating oleic acid(OA) to the short-chain semiconducting methylammonium lead iodide (MA4PbI6), called perovskite, uponthe photon harvesting efficiency and photovoltaic characteristics of bulk heterojunction (BHJ) polymericsolar cell comprising ternary photo active layer based on poly (3-hexyl thiophene)(rrP3HT) as electrondonor and PC61BM as acceptor. According to the photo absorption spectrum obtained within UV-Vis andNIR regions, the ternary cells based on OA and MA4PbI6 capped PbS exhibit enhanced photon harvestingefficiency compared with their binary counterpart cell. The steady state photoluminescence results revealefficient electron transfer from photoexcited P3HT to QDs and hole transfer from photoexcited QDs toP3HT, leading to the improved power conversion efficiency (PCE) of the ternary cells. However, comparedwith OA, the semiconducting perovskite (MA4PbI6) ligand shows to be much more effective in increasingpower conversion efficiency, so that 6% improvement in PCE is seen by the introduction of 6% PbS QDcapped with perovskite ligand unlike PbS QD with OA ligand which had adverse effect on the photovoltaicproperties of P3HT: PC61BM solar cell. This is explained to be due to the insulating characteristic of longchain OA as well as improved charge carrier transport in the case of PbS capped perovskite based ternarysolar cells.
