Environmentally compatible organic solar cells

They are light, flexible, and can be produced in many colors: Organic solar cells have many advantages over conventional cells and can be used in a variety of applications and designs. So far, manufacture of these solar cells or, to be more exact, precipitation of layers made of light-absorbing organic semiconductors has required the use of solvents harmful to health. In the UNICORN project, funded by the Federal Ministry of Education and Research (BMBF), KIT researchers, in cooperation with MJR PharmJet GmbH, have developed environmentally compatible processes for the coating and printing of organic semiconductors.
