Abstract:
Techniques for integrating photovoltaics into wearables, such as eyewear, are provided. In one aspect, a method of forming a lens for photovoltaic eyewear includes: forming a semitransparent photovoltaic film on at least a portion of a viewable area of the lens, wherein the semitransparent photovoltaic film includes an inorganic absorber material having a band gap of from about 1.4 eV to about 2.2 eV, and ranges therebetween. The semitransparent photovoltaic film can be configured to block greater than about 99.9% UVA, UVB, and UVC light rays, and from about 95% to about 99%, and ranges therebetween, of HEV light rays from passing therethrough. Photovoltaic eyewear formed by the present techniques is also provided.
