Organic photovoltaics (OPV) are solar cells that use organic materials to convert sunlight into electricity, as opposed to solar cells that use traditional optical semiconductors. Although OPV solar cells are less efficient than solar cells using conventional optical semiconductors, their higher productivity and the fact that they can be made from lightweight, flexible, and inexpensive materials make them promising for a variety of applications.
What is the efficiency of OPV solar cells?
