Abstract:
1. A method to produce a solar cell configured to produce an electrical signal in response to incident light, comprising: providing a transparent substrate having a surface; depositing a first transparent conductive layer on the surface of the transparent substrate; depositing a first doped diamond layer of a first type on the first transparent conductive layer; depositing a second doped diamond layer of a second type on the first doped diamond layer, wherein the first and second doped diamond layer form a p-n junction, wherein the p-n junction is responsive to at least a portion of the incident light such that the p-n junction converts the incident light into the electrical signal; and depositing a second transparent conductive layer on the second doped diamond layer, wherein: the p-n junction is adapted to convert an ultraviolet portion of the incident light into the electrical signal while permitting a visible portion of light to pass therethrough, the p-n junction having a band-gap configured to absorb ultraviolet incident light while the band-gap is not responsive to visible light, such that the p-n junction is configured to not convert the visible portion of incident light into the electrical signal; and one or more of the first doped diamond layer and the second doped diamond layer has a thickness in a range from about 0.1 microns to about 10.0 microns.
