Ultra-high efficiency, stability and low-cost perovskite solar cell materials Cs2Zr1-xTixI6

Insights into the relationship between ferroelectric and photovoltaic properties in CsGeI3 for solar energy conversion

“…This means that greater theoretical efficiency can be obtained within this approach simply by calculating the J-V characteristic with an absorption spectrum. [33][34][35][36]…”

Doping strategies for inorganic lead-free halide perovskite solar cells: progress and challenges

“…After doping with Cu, the absorption edge of Cs 2 AgBiBr 6 can be greatly expanded to the near-infrared (NIR) range, thanks to the intense absorption of sub-bandgap states. Tuyikeze et al 90 investigated the properties of double perovskite Cs 2 (Zr 1− x Ti x )I 6 ( x = 0.00, 0.25, 0.50, 0.75, 1.00), such as their stability and photoelectric properties. The results indicate that as the doping level of Ti 4+ increases, the bandgap decreases.…”
