An empirical analysis of ZnO/Ag nanocomposites thin film organic solar cell with optical and structural properties

Abstract

For organic solar cells (OSCs), a novel polymer donor (PMMA) and a new small molecule acceptor (Ag NPs) were devised and produced. The effects of the donor and acceptor on the absorption spectra, molecular energy levels, and charge mobilities were thoroughly investigated. The results showed that the PMMA/ZnO/Ag NPs OSCs exhibited a high power conversion efficiency of 5.7%, which is attributed to the complementary absorption spectra, matched energy levels, and efficient charge transport. These findings suggest that PMMA and Ag NPs are promising materials for the development of high-performance OSCs. The PMMA-based OSC device demonstrated with a thickness of 200–300 nm achieving an efficiency of over 5.7%, indicating the promise of photovoltaic OSCs in practical applications. The findings were used to regulate nanomorphology and ultimately improve solar cell performance.
