Ion migration is considered the key cause of instability for perovskite solar cells. It occurs when the soft crystal lattice and relatively weak bonds in the perovskite film lead to low formation ...
“The technique of doping with host lattices is commonly employed to modify the perovskite lattice structure and enhance the performance of PV systems, often involving the incorporation of materi ...
the modulus and hardness of the perovskite thin film were doubled, significantly restraining lattice dynamic expansion effects under illumination conditions," he said. In their research ...
"Trace amount of SCN ions in the bulk enter the perovskite lattice, forming an I/Br/SCN alloy, and occupy iodine vacancies, blocking halide ion migration via steric hindrance," Zhang, Chen and ...
One approach to boost gate capacitance without decreasing the thickness of gate insulators or gate dielectrics entails the use of insulating materials with a high dielectric constant (κ), such as ...
