Flexible perovskite solar cells
A perovskite solar cell (PSC) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Perovskites have inherent properties such as broad absorption spectrum, fast charge separation, long electron and hole transport distance, and long carrier separation lifetime, making them very promising solid-state solar cell materials.
How perovskite solar cell work?
Perovskite solar power is similar to most photovoltaic technologies under the photovoltaic effect. Photons in sunlight hit the perovskite absorber layer, exciting and releasing electrons, forming electron-hole (e-h) pairs. The electrons then move towards the HTL, which transports the electrons to the conductor to power the load.
After the electrons power the load by flowing as current, they are collected by the ETL in the perovskite solar panel, a layer that also inhibits the backflow of holes. Excited electrons may fill holes rather than act as a current overload, which explains some of the solar power loss during surface recombination into perovskites.
There are two main technical directions for the application of perovskite materials in the photovoltaic industry: Single-junction perovskite solar cells and perovskite tandem solar cells. Single-junction perovskite technology is similar to other thin-film technologies, and the manufacturing cost is expected to be lower than that of current thin-film solar cells. Dazheng company is specializing in developing and manufacturing flexible single-junction perovskite solar cells. Flexible solar cells have great potential in photovoltaic applications. Traditional flexible thin-film solar cells are limited by materials and technology, with high cost and low market acceptance, which are not conducive to portability and narrow application. The flexible perovskite solar cells CAN be solved this problem. It not only has a simple preparation process and low material cost, but also has high efficiency and good stability. At the same time, the solar cell is as thin as paper, which is convenient for carrying and has a wider applications. The perovskite film of our flexible perovskite solar cell is formed by wet process, and then various functional films are uniformly deposited on it through PVD and can be achieve roll-to-roll production processes.
