The Institute of Energy Conversion (IEC) at the University of Delaware is the oldest solar energy research institute in the world. It was established by Karl Boer in 1972 to pioneer research on thin film solar cells and today is one of the only laboratories in the world with expertise in Si, CdTe, and CuInSe2 based solar cells. This included the development of one of the first solar powered homes, a structure still utilized by the university's student-run ambulance service, the University of Delaware Emergency Care Unit. Recently the IEC was the number one recipient of the DOE Sunshot Initiative and was awarded 5 grants totaling $9.1 million to research next generation solar cells to reduce the cost of solar cells by 75% by the end of the decade.
