Hybrid Solar Cells with Outstanding Short-Circuit Currents Based on a Room Temperature Soft-Chemical Strategy: The Case of P3HT:Ag2S

P3HT:Ag2S hybrid solar cells with broad absorption from the UV to NIR band were directly fabricated on ITO glass by using a room temperature, low energy consumption, and low-cost soft-chemical strategy. The resulting Ag2S nanosheet arrays facilitate the construction of a perfect percolation structur...

Description
Summary:P3HT:Ag2S hybrid solar cells with broad absorption from the UV to NIR band were directly fabricated on ITO glass by using a room temperature, low energy consumption, and low-cost soft-chemical strategy. The resulting Ag2S nanosheet arrays facilitate the construction of a perfect percolation structure with organic P3HT to form ordered bulk heterojunctions (BHJ); without interface modification, the assembled P3HT:Ag2S device exhibits outstanding short-circuit current densities (J sc) around 20 mA cm–2. At the current stage, the optimized device exhibited a power conversion efficiency of 2.04%.
