Finally, we model optimizations to the HVPE-grown GaAs top cell and provide a near-term pathway to 31.4% efficiency with a low-cost III–V deposition technique. Firstly, the D-HVPE process reduced costs and now aluminum growth means improved efficiency. Earlier this year, Magnolia Optical Technologies revealed it is working with DARPA to develop high efficiency GaAs-based solar cells for military portable power as well as potential drone and space applications. III-Vs also benefit significantly from what [cadmium telluride solar cell manufacturer] First Solar benefits from, which is a very good temperature coefficient. Sol Voltaics aerosol growth process promises to kick-start a market for terrestrial solar cells based on GaAs, Richard Stevenson interviews Sol Voltaics CEO Erik Smith. Several companies and research institutes, however, are working on methods of bringing down production costs for GaAs and III-V solar cells – which include materials from those groups of the periodic table – to acceptable levels for commercial production. He presented calculations based on the MOCVD growth of a five micron-thick III-V film, and concluded that costs would need to fall by two orders of magnitude before this technology could make an impact. As stated earlier, GaAs thin-film solar cells have reached nearly 30 percent efficiency in laboratory environments. 4.6 (11) "Good supplier" "Fast shipping" Contact Supplier. Hold Ctrl or Cmd to select multiple editions. Do you agree with this view that if III-Vs are to have a place in the terrestrial solar cell market, the technologies that are to be used need to be many tens of times lower in cost than they would be with traditional techniques?A: There's no way that you can grow an MOCVD-based film and have a tandem that is cost effective. And those are also recycled.Q: You have raised tens of millions of dollars in funding. So it depends what your goal is.Q: What's the attraction of a III-V-and-silicon cell in the terrestrial market? We compare these results to an MOVPE-grown GaAs//Si tandem cell that has the same structure. Within the gallium arsenide community it is known how to improve all those things.
