perovskitePerovskite semiconductors are regarded as next-generation photovoltaic materials owing to their superb optoelectronic properties, including an excellent carrier diffusion length, strong light absorbption, low defect density, and solution processability. The PCE of lead perovskite solar cells (LPSC)...
Low bandgap tin–lead iodide perovskites are key components of all-perovskite tandem solar cells, but can be unstable because tin is prone to oxidation. Here, to avoid a reaction with the most popular hole contact, we eliminated polyethylenedioxythiophene:polystyrenesulfonate as a hole transport laye...
Crystalline porous materials in perovskite solar cells: a mutually beneficial marriage The remarkable efficiency achieved by metal halide perovskite solar cells (PSCs) has established them as a significant advancement in thin-film photovoltaic technology in recent years. However, the susceptibility of hali...

The photovoltaic performance and stability of tin–lead perovskite solar cells (PSCs) are undermined by the reaction between the perovskite layer and the commonly used hole contact, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). In addition to its acidity issue, the PSS ...
Halide perovskites are rising as star materials for next-generation solar cells. However, the state of the art lead perovskite still needs to be upgraded since: firstly, the heavy metal character of lead may cause an environmental concern1,2; secondly, according to Shockley–Queisser limitation, ...

The efficiency of Lead perovskite solar cells (Pb-PVK-PV) is now 26.1 % which is close to that of silicon solar cells (26.8%) (1). The research has been shifted to the fabrication of the large modules and the module stability. After the research of the Pb-PVK-PV, Tin perovskite sola...
Sn‐based halide perovskites are the most promising alternatives for developing Pb‐free perovskite solar cell materials. However, the stability of Sn halide perovskites is the biggest concern for future developments. The phase stability and the doping﹍evel control should be resolved for Sn perovskites...
