Abstract

A method for making a tandem solar cell includes the steps of providing a ceramic substrate, providing a titanium-based layer on the ceramic substrate, providing an n+-p−-p+ laminate on the titanium-based layer, passivating the n+-p−-p+ laminate, providing an n-i-p laminate on the n+-p−-p+ laminate, providing a p-type ohmic contact, providing an n-type ohmic contact providing an anti-reflection layer of SiCN/SiO2 on the n-i-p laminate.
