2. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application
Abstract : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. READ MORE

3. Excited state dynamics in low-dimensional perovskite nanocrystals
Abstract : Two-dimensional (2D) perovskites have emerged as promising building blocks for optoelectronic applications. To fabricate high-performance devices, the relation between the material structures and their function in terms of excited state and charge carrier dynamics need to be well understood. READ MORE
