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
Dependent Claim 17 words
A solar cell as claimed in Claim 1, characterised in that the silicon portion amounts to 1.3%.
Claim 4
Dependent Claim 25 words
A solar cell as claimed in Claim 1, characterised in that the aluminium-silicon alloy contains with a portion of at least 1% silicon, 0.1-0.2% titanium.
Claim 5
Dependent Claim 40 words
A solar cell as claimed in one of Claims 1 to 3, characterised in that the layer thickness of the aluminium/silicon or aluminium/silicon/titanium layer (2) amounts to 500 to 1000 nm and the specific resistance to 3 gohm . cm.
