Organic solar cells reach record efficiency, benchmark for commercialization

24.04.2018 | University of Michigan | www.umich.edu

In an advance that makes a more flexible, inexpensive type of solar cell commercially viable, University of Michigan researchers have demonstrated organic solar cells that can achieve 15 percent efficiency. This level of efficiency is in the range of many solar panels, or photovoltaics, currently on the market.

At 15 percent efficiency and given a 20-year lifetime, researchers estimate organic solar cells could produce electricity at a cost of less than 7 cents per kilowatt-hour. In comparison, the average cost of electricity in the U.S. was 10.5 cents per kilowatt-hour in 2017, according to the U.S. Energy Information Administration.

Record efficiency of organic solar cells

Organic solar cells incorporate carbon into their construction to offer several advantages over conventional “inorganic” cells. Silicon-based inorganic solar panels are costly to make—composed of thick, rigid sheets that require fixed installation points.
