The preparation of textured Te thin films with pronounced acicular morphology and concomitant high absorptivity
- 33 Downloads
The dependence of surface morphology, and resultant absorptivity, on deposition angle for vacuum deposited Te films has been studied. A deposition angle of 80° was found to yield surface morphologies comprised of acicular crystallites of appropriate dimension and geometry for the trapping of solar incident radiation through multiple reflection. Solar absorptivities across the visible spectrum as high as 95% are manifested by such surfaces.
