A PHOTOVOLTAIC CELL AND A METHOD OF FORMING A PHOTOVOLTAIC CELL

摘要

The present disclosure provides a photovoltaic device comprising a copper-based light-absorbing material and a first material electrically coupled to the light-absorbing material and forming a p-n junction with the light- absorbing material. The device further comprises an intermediate material arranged between the first material and the light-absorbing material. The intermediate material acts to reduce the minority carrier recombination rate at the region between the light-absorbing material and the first material and/or optimise the electronic band alignment in the photovoltaic device.
