Built by Danish researchers, the device also achieved a power conversion efficiency of 5.0%. They designed the cell with a soda-lime glass substrate, a tin oxide (FTO) layer, an electron transport layer made of titanium oxide (TiO2), a selenium absorber, a molybdenum oxide (MoOx) layer, and a gold (Au) metal contact.
