Title: Development of nanocomposite materials enabling to enhance stability and efficiency of hybrid solar cells

Abstract: Si-wafer-based solar cells (SWSGs) currently dominate the photovoltaic market with ~ 90% of the market share. Half of their cost comes from manufacturing of silicon wafers. High-cost compared to that of fossil fuels has restricted their wide adoption for renewable energy. Therefore, solution-processed solar cells have attracted enormous interests owing to their potential low-cost via roll-to-roll fabrication methods at low temperature. In recent years, significant progress has been made in polymer and hybrid solar cells (PHSGs). Particularly for halide perovskite-based solar cells, their power conversion efficiency has matched to that of SWSGs. However, the main issue faced by PHSGs is their poor stability, which deters the large-scale deployment. Hybrid nanocomposite (NC) materials can play their key roles on enhancement of stability and efficiency for PHSGs; e.g. a sol-gel/PEDOT:PSS NC material reveals a “water-impermeable” property as hole transport layer in solar cells and polymer-perovskite nanocomposites provide a novel route for exploring stable and high-efficient light absorber. This talk will present our recent work (patented technologies) in these aspects.,
