Double-layered anti-reflective coating for heterojunction solar cells

South Korean scientists have developed a novel coating that purportedly reduces average cell reflectance and significantly increases short-circuit current. The coating is based on aluminum oxide and indium tin oxide.Researchers from Sungkyunkwan University (SKKU) in South Korea have developed an anti-reflective coating for silicon heterojunction solar cells that can purportedly improve lower short-circuit current (Jsc), which is one of their well-known weaknesses. The scientists said that heterojunction cells based on thin wafers have low absorption efficiency in the red and near-infrared portions ...
