Antimony sulfide (Sb2S3) and selenide (Sb2Se3) are emerging earth-abundant absorbers for photovoltaic applications. Solar cell performance depends strongly on charge-carrier transport properties, but these remain poorly understood in Sb2X3 ...
Interplay of Kinetic and Thermodynamic Reaction Control Explains Incorporation of Dimethylammonium Iodide into CsPbI3 [0.03%]
动力学和热力学竞争解释了甲铵碘化物在CsPbI3中的引入作用
Aditya Mishra,Dominik J Kubicki,Ariadni Boziki et al.
Aditya Mishra et al.
CsPbI3 is a promising material for optoelectronics owing to its thermal robustness and favorable bandgap. However, its fabrication is challenging because its photoactive phase is thermodynamically unstable at room temperature. Adding dimeth...
