Abstract:
1. A method for making a tandem solar cell comprising the steps of: providing a ceramic substrate; providing a titanium-based layer on the ceramic substrate; providing an n using a plasma-enhanced chemical vapor deposition device to provide SiCNO:Ar plasma to passivate the n providing an n-i-p laminate on the n using potassium hydroxide solution and a patterned mask to etch a portion of the n-i-p laminate and providing a p-type ohmic contact; using a patterned mask to provide a Ti/Pd/Ag layer on the n-type amorphous silicon carbide layer and annealing the Ti/Pd/Ag layer in argon, thus forming an n-type ohmic contact; and using a patterned mask to provide an anti-reflection layer of SiCN/SiO
