Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
55 words
A photovoltaic radiation detector element comprising: a body of semiconductor material; an electrically conductive current collector attached to said body and formed with a plurality of thin branch segments connected at a common point; and a photovoltaic junction forming coating on said body which closely approaches but is spaced from said current collector branch segments.
Claim 2
Dependent Claim
55 words
A photovoltaic radiation detector element comprising: a body of semiconductor material; an electrically conductive current collector attached to said body and formed with a plurality of thin branch segments connected at a common point; and a photovoltaic junction forming coating on said body which closely approaches but is spaced from said current collector branch segments.
Claim 3
Dependent Claim
26 words
The detector element of claim 1 wherein said body is a wafer and said current collector branch segments radiate from the center of one face thereof.
Claim 4
Dependent Claim
28 words
The detector element of claim 2 wherein said current collector includes arm segments disposed normal to branch segments radiating from the center of one face of said wafer.
Claim 5
Dependent Claim
