Researchers from Nankai University (Tianjin) and the Beijing Institute of Technology have published a study on a new perovskit photovoltaic device with inverted architecture. Named p-i-n, as opposed to the standard n-i-p configuration, it places the selective layer of holes at the base of the device and the electron transport device at the top. For years, that configuration carried a penalty of efficiency with respect to conventional cells, main…
