Abstract

This study experimentally investigates the ability of Bi2O 3/P3HT heterojunction thin films to improve the power-conversion efficiency of InGaN-based photovoltaic (PV) devices. InGaN-based PV devices combined with Bi2O3/P3HT heterojunctions were prepared using the pulsed laser deposition method. The Bi2O3/P3HT heterojunction creates carriers that combine with excitons through the light-absorbance process, which enhances the power-conversion efficiency of InGaN PV devices by approximately 36%. Thus, these Bi2O 3/P3HT heterojunctions can provide an efficiency improvement in InGaN PV devices and other related solar-cell applications.
