What's Perovskite solar cells?4 answersPerovskite solar cells (PSCs) are thin-film photovoltaic devices that have gained attention in recent years due to their high conversion efficiency, simple preparation process, and low cost. They are considered a promising third-generation solar cell. PSCs utilize perovskite materials, which have excellent optoelectronic properties such as high absorption coefficients, long carrier diffusion length, and tunable band gap. The power conversion efficiency (PCE) of PSCs has increased from 3.8% to 25.8%, approaching that of commercial silicon solar cells. PSCs can be used in tandem solar cells to further increase efficiency beyond the theoretical limit. Additionally, the concept of phase heterojunction (PHJ) solar cells has been demonstrated using different polymorphs of the same material, resulting in improved photovoltaic parameters. Overall, PSCs offer a promising alternative to traditional solar cells, with ongoing research focused on improving efficiency, stability, and reducing toxicity.
How does a perovskite solar cell work?5 answersA perovskite solar cell works by utilizing a layered structure to convert sunlight into electricity. The structure typically includes a transparent conductive substrate, an electron transport layer, a perovskite light absorption layer, and a metal electrode. The electron transport layer helps inhibit carrier recombination and increase the short-circuit current and open-circuit voltage of the solar cell. In some cases, multiple active layers are used to form a perovskite active layer with a gradient ratio change, which improves the transmission efficiency of excitons and enhances the cell's performance. Additionally, perovskite solar cells can be combined with other types of solar cells, such as quantum dot, organic, or thin film solar cells, to create tandem solar cell structures. The performance of perovskite solar cells depends on factors such as the composition and architecture of each layer, as well as the synthesis methods and selection of electron and hole transport materials. By increasing the light receiving area of the perovskite absorption layer, the photoelectric conversion efficiency of the perovskite solar cell can be effectively improved.
