Abstract
A device for the detection of electromagnetic radiation, wherein the device has (i) a photoactive layer of a semiconductor having a band gap of greater than 2.5 eV, (ii) a dye applied to the semiconductor, and (iii) a charge transport layer comprising a hole conductor material, where the hole conductor material is preferably solid and amorphous.
Claims24
A device for the detection and determination of the intensity of electromagnetic radiation, wherein the device comprises a matrix of detectors which have
- (i) a conductive layer,
- (ii) a photoactive layer of a semiconductor having a band width of greater than 2.5 eV which is applied to said conductive layer,
- (iii) a dye applied to the semiconductor,
- (iv) a charge transport layer comprising a hole conductor material applied above said dye applied to the semiconductor
- (v) a counter-electrode layer applied to said charge transport layer and
- (vi) insulating layers,
- wherein at least one side of the detector is transparent to the electromagnetic radiation and the detectors of said matrix are connected in parallel to an electronic measurement device.
The device as claimed in claim 20, wherein said dye is a photochromic dye, said semiconductor is a metal oxide and said hole conductor material is soluble in organic solvents.
