Abstract

In this study, ZnO-WO₃ nanoparticles are prepared by sol-gel technique. Various characterization techniques have been utilized for studying morphological, optical as well as structural properties of the synthesized nanostructures. Two sets of inverted organic solar cells have been constructed by the chemically synthesized ZnO-WO₃ nanoparticles as electron transport layer (ETL) and as hole transport layer (HTL) and the solar cell characteristics were examined. The first solar cell (device A) employing ZnO-WO₃ as ETL was fabricated with configuration ITO/ZnO/ZnO-WO₃/PTB7-Th:PC71BM/MoO₃/Ag while the other solar cell (device B) employing ZnO-WO₃ as HTL was fabricated with structure ITO/ZnO/PTB7-Th:PC71BM/ZnO-WO₃/MoO₃/Ag. In comparison to the device A with ZnO-WO₃ as ETL, a remarkable improvement is seen in device B with ZnO-WO₃ as HTL. An efficiency of 1.88% is observed in device B in comparison to the efficiency of 0.64% in device A. Our results suggest that ZnO-WO₃ nanoparticles have great potential in photovoltaics.
