Light-Matter Interaction in Emerging Semiconductors

Our appetite for clean energy and the necessity to cut emissions have pushed the research community to find renewable energy sources. Photovoltaics is an ideal and effective source to convert sun rays into electricity. In the last decade, perovskite solar cells (PSC) based research has emerged as a potentially attractive means to harvest solar energy, and power conversion efficiency (PCE) as high as 25.8%, in lab-scale devices has been measured. Though the improvement in PCE is high, their long-term stability, and reproducibility, have plagued its immediate commercialization endeavor. In our efforts to identify rational light harvesters, current efforts are being made to the employment of formamidinium lead triiodide (FAPbI3) owing to its favorable optical band gap (1.47 eV), high tolerance factor, and phase stability. In this talk, I will discuss our recent efforts in improving reliability, through interface optimization, compositional engineering, and designing innovative charge selective layers in perovskites and kesterites based semiconductors.
