State-of-the-art III-V multijunction cells have achieved a record efficiency of 42.8%, which has fueled great interest in the utility sector for large-scale deployment. However, III-V solar cells have thus far proven too expensive for widespread terrestrial applications due to the combined cost of substrates, growth processes, and materials. Here, we propose a novel III-V solar cell based on the epitaxial...
We report on the experimental observation of the effect of periodic hole arrays in the infrared reflection spectra of suspended polycrystalline silicon carbide (poly-SiC) membranes. The poly-SiC was deposited by low pressure chemical vapor deposition (LPCVD), patterned with contact photolithography, and etched by reactive ion etching (RIE). The spectra are shown to be strongly dependent on the pitch...
