perovskite solar cellSnO2Perovskite solar cells (PSCs) may offer huge potential in photovoltaic conversion, yet their practical applications face one major obstacle: their low stability, or quick degradation of their initial efficiencies. Here, a new design scheme is presented to enhance the PSC ...

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 ...
This demonstrated, for the first time, that the perovskite material could effectively transport electrons without the underlying TiO2 layer. This insight prompted the next advancement; the demonstration of a planar geometry solar cell with a perovskite thin film as the absorber layer [16]. The high...
perovskite solar cellsstabilityDevice stability is the most urgent issue that hinders perovskite solar cell (PSC) commercialization, given the achieved efficiency of PSC that exceeds 23%. The perovskite materials and contact layers throughout the device stack have been scrutinized with regard to ...
Methylammonium lead iodide (CH3NH3PbI3) perovskite solar cell (PSC) is one of the third generations of photovoltaic (PV) research interest in recent years. The solar cell degrades very fast in ambient air and this poses major challenge for its commercialization. Hence, this report investigates ...
technology,” Meng said. In less than two years, the Yang team has advanced perovskite solar cell efficiency from less than 1 percent to close to 20 percent. “But its short lifespan was a limiting factor we have been trying to improve on since developing perovskite cells with high ...
Perovskite solar cells must overcome the long-term stability problem in order to be put into practical use. Materials science, through the development of synthetic chemistry, materials characterization and device engineering can contribute to improvements in stability and scalability towards enabling large ...
Researchers at EPFL and Northwestern University have unveiled a groundbreaking design for perovskite solar cells, creating one of the most stable PSCs with a power-conversion efficiency above 25%, paving the way for future ...
"The solar cell we have now presented in Nature Energy, on the other hand, impresses with its exceptional stability. The values are certainly among the best ever measured for a planar perovskite solar cell in a long-term test," Brabec said. The illuminated cell had to survive 1450 hours at...
