Founded in 2007, Solterra Renewable Technologies began with a vision of manufacturing quantum dot solar cells worldwide to replace greenhouse gas from carbon-emitting energy sources with clean solar energy. We strive to be the world's leading solar energy technology company through the commercialization of sustainable and cost-effective 3rd generation quantum dot solar cell technology. By setting the standard for solar technology with distinctly superior cost and capital efficiency, Solterra will deliver better than grid-parity solar electricity with a goal of Lowest Cost of Energy (LCOE).   The Solterra thin film quantum dot photovoltaic solar cell is differentiated from other solar cells in several important ways including a dramatically lower manufacturing cost per watt because no vacuum equipment is required, no expensive silicon is required and low-cost printing techniques are used on inexpensive substrates. Also, Solterra’s solar cell has higher potential efficiency (~65%), because quantum dots are capable of producing multiple charge carriers when excited. Silicon solar cells on the other hand generate only one electron-hole pair per incident photon, irrespective of their energy.
