Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
60 words
A solar cell comprising a semiconductor body which consists of amorphous silicon and which is applied to a substrate provided at least at its surface with a metal layer which serves as rear contact, characterised in that the metal layer (2) consists of an aluminium-silicon alloy with or without a titanium addition with a silicon portion of less than 2%.
Claim 2
Dependent Claim
60 words
A solar cell comprising a semiconductor body which consists of amorphous silicon and which is applied to a substrate provided at least at its surface with a metal layer which serves as rear contact, characterised in that the metal layer (2) consists of an aluminium-silicon alloy with or without a titanium addition with a silicon portion of less than 2%.
Claim 3
