Nanowire technology has made breakthroughs in efficient solar modules

This breakthrough paved the way for SolVoltaics to bring SolFilmTM PV solutions to market, which can increase solar module power up to 50% at a very low cost. Advanced photovoltaics company SolVoltaics completed the manufacture of photovoltaic (PV) nanowires using its patented Aerotaxy® technology, which is a major leap forward in the company's commercialization of popular solar energy conversion efficiency enhancement technologies. This breakthrough paved the way for SolVoltaics to bring SolFilmTM PV solutions to market, which can increase solar module power up to 50% at a very low cost. Solriktacs CEO Erik Smith stated: “Today's achievement is by far the most important for SolVoltaics. The production of solar nanowires using Aerotaxy technology is the key to the manufacture of SolFilm. The top and bottom wires of nanowire growth have opposite doping profiles. This makes each nanowire a full-featured solar cell, ie, a wire-length pn junction. Whether the component manufacturer will use our products independently to increase efficiency and reduce costs, or use it to strengthen existing technologies, we believe that SolFilm will open a new era of solar energy conversion efficiency, which not only brings great value to solar manufacturers but also to solar energy companies and consumers." In recent years, the trend of increasing solar energy efficiency with the increase of economic scale has decreased significantly, and the annual average efficiency of traditional components has increased by only 0.2-0.3%. Many emerging efficiency-enhancing technologies are expensive and lack stability or reliability. In contrast, SolFilm can build economically viable bridges for solar panel manufacturers, using proven materials to achieve unprecedented efficiencies. SolFilm is a lightweight, convenient photonic film consisting of billions of gallium arsenide (GaAs) nanowires facing the Sun. Each nanowire is a complete solar cell that can directly convert high-energy sunlight into electricity. Previously used in space and concentrating solar projects, gallium arsenide has long been favored by the mainstream solar industry. However, so far, due to its high manufacturing cost, it has not yet been economically feasible for the manufacture of large-scale solar panels. Nanowires manufactured using the Aerotaxy® process significantly reduce the amount of GaAs required and do not require crystallized support wafers, which significantly reduces material costs. Recent research results show that SolVoltaics has achieved a technological leap: while reducing the price of solar energy, it has unprecedentedly increased the power of traditional solar cell components. Last year, SolVoltaics was the first company to successfully arrange nanowires in thin films. Recently, it was named “Company of the Year” by the famous Rapidus Award in recognition of the company’s outstanding innovation and its great potential for future success. The company also completed a record $17 million in new financing last year, including investments from the Swedish Energy Agency and the EU's 2020 Horizonz research and innovation program.
