Abstract
A method of producing an absorber layer for solar cells by electrolytic dispersion deposition.
Claims12
A method of producing a ternary semiconductor absorber layer for solar cells, comprising:
- electrolytically depositing a binary alloy of elements of Groups IB and IIIA on an electrically conductive substrate in an electroplating bath and simultaneously incorporating a third alloy component of Group VIA suspended in the electroplating bath in finely dispersed form by dispersion electrolysis, and
- producing a ternary semiconductor layer of the type IB-IIIA-VIA by heat treating the deposited material.
