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.

National Energy Board: the whole county roof distributed photovoltaic development pilot work started, the government installation ratio of not less than 50%

Recently, the National Energy Board comprehensive department issued a notice on the submission of the whole county (city, district) rooftop distributed photovoltaic development pilot program. The notice points out that the whole county (city, district) roof distributed photovoltaic construction, is conducive to the integration of resources to achieve intensive development, is conducive to the elimination of power peak load, is conducive to saving and optimizing investment in the distribution network, is conducive to guiding residents to green energy consumption, is to achieve "carbon peak, carbon neutral" and rural revitalization of the two major national strategies. It is an important measure to realize the two national strategies of "carbon peak and carbon neutral" and rural revitalization.
