TU Delft presents 21.14%-efficient IBC-HJT solar cell based on molybdenum oxide hole collector

Researchers at the Delft University of Technology have fabricated an interdigitated back contact and heterojunction solar cell that uses a thin full-area molybdenum oxide layer as a blanket layer. The device reportedly ensures well-passivated gaps between electron and hole collecting regions. Scientists at Delft University of Technology in the Netherlands have designed a solar cell with an interdigitated back contact (IBC) and heterojunction (HJT) architecture that uses an electron collection contact stack based on molybdenum oxide (MoOx). MoOx is a transition metal oxide (TMO) nanomaterial that ...
