The Department of Energy has begun funding solutions to the engineering and infrastructure problems that must be solved before widespread commercialization of current photovoltaic technologies can become a reality. Called the Solar America Initiative, the 2007 DOE Budget set aside $148 million to accelerate the development of photovoltaic cells ranging from those made from monocrystalline, polycrystalline and amorphous silicon structures, as well as those based on thin films, organic polymers and quantum wells. The U.S. Department of Energy has issued a Notice of Program Interest to the industry, universities and other potential partners to help plan topics, program phases, technologies and procurement strategies to meet its goal. To start, Solar America will try to see what obstacles remain to commercialization, then enlist EEs and others to solve those problems. The program aims to develop multiple competing solar cell technologies by 2015 to provide electricity at a cost per kilowatt-hour that equals or exceeds what the grid offers.
