Abstract for Presentation
Efficient perovskite solar cells and light-emitting diodes
Halide perovskite materials own excellent semiconductor properties, which showed great potential in photovoltaic and emission display. In this talk, I will summarize our recent work in perovskite solar cells (PSCs) and light-emitting didoes (PeLEDs). 1). By charge transport layer and perovskite composition engineering, for the bandgap around 1.5 electron volt, we have achieved close to 25 percent efficiency with the FF around 85 percent of organic-inorganic PSCs; 2). By surface re-construction, we have pushed the PCE of inorganic perovskite CsPbI3 based solar cells to 20 percent efficiency; 3). According to several strategies, such as non-radiative recombination suppression, band structure modulation and charge injection balance, we have achieved over than 25 and 16 percent external quantum efficiency electroluminescence in red and blue region, respectively.
