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.

Perovskite materials

A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Perovskites have a nearly cubic structure and the chemical formula is ABO3. Typically perovskite compounds have the chemical formula ABX3, where "A" and "B" represent cations and X is an anion bound to both. A large number of different elements can combine to form a perovskite structure. Using this compositional flexibility, scientists can design perovskite crystals with a variety of physical, optical, and electrical properties. Today, perovskite crystals are found in ultrasonic machines, memory chips and current solar cells.

On July 19,2022, Nikkei reported Dazheng mass production of 40 * 60cm perovskite solar cell module

A Chinese company has launched the world's first mass production of large modules of new solar cells. The new solar cells are bendable and ultra-thin flexible perovskite cells. Although the manufacturing cost is three times that of existing photovoltaic cells, it may be reduced to half that of silicon type cells in the future. At present China leads the way of perovskite cell in mass production.
