As such, one way to improve perovskite solar cell stability is to replace the organic “A-cation” in the ABX3 structure. The organic cation has little impact on the electrical properties or band structure of the perovskite layer. Its main role is to balance charge within the crystal ...

proposed that a polymer solar cell module could be fabricated with an energy payback time of only one day, given advances in efficiency and stability [1]. Over a period of approximately 20 years, the power conversion efficiency (PCE) of polymer solar cells progressed to 12% [6]. Importantly...
Here, we systematically discuss the degradation mechanism for perovskite materials and their corresponding solar cell devices with a focus on the n‐i‐p structure. Developed strategies for improving device stability are also summarized. We hope this review will provide helpful insights for next stage...

Together with his team and a number of international partners, he has investigated a chemical variation that significantly improves the stability of the perovskite thin film in different solar cell architectures, among them the p-i-n architecture, which normally is a little less efficient than the...
prototype organic hole-transporting materials (HTMs,selectively transporting positive charges in a solar cell) have been able to achieve power-conversion efficiencies over 20%. And by virtue of their ingredients, these hole-transporting materials adversely affect the long-term operationalstabilityof the ...
Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However, the lack of long-term stability, primarily stemming from the interfacial defects and the susceptible metal electrodes, hinders their practical application. In the past few years, two-dimensional (2D) materia...
Consequently, this work implies that ambient stability of perovskite solar cell can be achieved from surface-passivation of perovskite layer for commercialization of the PSCs. Introduction New generation solar cells with high Power Conversion Efficiency (PCE) have been researched for past decades for ...
