Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
38 words
A photosensitive transducer which comprises, in sequence, a substrate, a photoconductive amorphous silicon layer and a colorant layer comprising a photoconductive dye or pigment adapted to provide said amorphous silicon layer with enhanced photoconductivity and modified spectral sensitivity.
Claim 2
Dependent Claim
38 words
A photosensitive transducer which comprises, in sequence, a substrate, a photoconductive amorphous silicon layer and a colorant layer comprising a photoconductive dye or pigment adapted to provide said amorphous silicon layer with enhanced photoconductivity and modified spectral sensitivity.
Claim 3
Dependent Claim
23 words
A photoelectric transducer according to claim 1 in which the photoconductive layer and the colorant layer are sandwiched between a pair of electrodes.
Claim 4
Dependent Claim
15 words
A photoelectric transducer according to claim 1 in which the photoconductive layer contains hydrogen atoms.
Claim 5
Dependent Claim
18 words
A photoelectric transducer according to claim 3 in which the photoconductive layer contains 1-40 atomic percent of hydrogen.
