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...
Perovskite 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) rapidly ...
Tin‐based perovskites with excellent optoelectronic properties and suitable bandgaps are promising candidates for preparing efficient lead‐free perovskite solar cells (PSCs). However, it is challenging to prepare highly stable and efficient tin‐based PSCs because Sn2+ in perovskites can be easily ...
With record PCEs surpassing 13%33, Sn-based perovskite solar cells have steadily become more competitive due to intensive research efforts. However, the device performance of tin perovskite solar cells has advanced at a slower pace relative to their Pb counterparts, mainly due to their poorer stab...
Tin-lead perovskites provide an ideal bandgap for narrow-bandgap perovskites in all-perovskite tandem solar cells, fundamentally improving power conversion efficiency. However, light-induced degradation in ambient air is a major issue that can hinder the
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...
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 ...
