Scientists in Canada fabricated a perovskite solar cell based on an inverted structure that achieved 23.9% efficiency, and maintained 92% of its initial performance after 500 hours of accelerated aging tests. By carefully controlling the thickness of the perovskite layer, the group was also able to gain control of "quantum mechanics" properties such as the movement of electrons within the layer and the wavelengths of light absorbed.While it is now widely accepted that the question for perovskite solar cells in mass production is "not if, but when", a wealth of different approaches to the material ...Den vollständigen Artikel lesen ...
