AbstractRecent innovations in noncrystalline solar cells are beginning to emerge as viable replacements to traditional CVD grown single crystal counterparts in applications that demand high specific power, low product cost ($/sq.ft.) and ultimately scalable unit energy cost ($/W). Future NASA missions stand poised for adopting these new photovoltaics systems that are deposited onto lightweight, flexible substrates. Nanohmics proposes to fabricate a heterojunction solar cell composite consisting of high weight fraction titanium dioxide nanoparticles blended with amphiphilic, regioregular conducting polythiophene that are highly organized at an air-water interface. Furthermore, Nanohmics is proposing to prepare a novel device geometry that involves a low-cost, co-axial deposition process of all the cell layers onto core metal (e.g. copper, aluminum) or metal-coated fibers. Deposition of the blocking layers, heterojunction phase, and transparent conducting electrode in this fashion will lead to individual solar cell "threads", SuntwineTM.
