Dazheng's flexible chalcogenide solar cell device efficiency exceeds 21%
Over 21%!!! The latest efficiency of Taisheng Microna's flexible calcium titanite cells is out!
Today Dazheng Microna announced that the company's self-developed flexible chalcogenide cell efficiency has reached a new high, with a photoelectric conversion efficiency exceeding 21%. The company has once again set a new record for the world's highest efficiency of flexible calcium titanite battery, and continues to lead the field of flexible calcium titanite battery.
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.
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.
Tandem solar cells are an important strategy to push the Shockley-Queisser (S-Q) efficiency limit of single-junction solar cells, it can be lower the cost per watt.
