Outline of Final Research Achievements

In this project, we were exploring the new photovoltaic conversion process and its application for solar cells in atomically thin transition metal dichalcogenides. The new method for evaluating the photoluminescence quantum efficiency is proposed. We obtained new insights for understanding the optical properties and photovoltaic conversion process. Moreover, the high photovoltaic conversion efficiency of 11.1% is realized using the transition metal dichalcogenides as the carrier blocking layer in graphene/MoS2?Si heterojunction solar cell.
