Organic photovoltaics: Potential fate and effects in the environment

► Environmental fate and ecotoxicity aspects of organic photovoltaics (OPV) need to be investigated. ► For the first time, a typical bulk heterojunction OPV was discussed concerning its environmental impact layer by layer. ► We conclude that there is a general lack of information about fate and potential ecotoxicity of many main OPV components. ► The little information available does not evidence any immediate risk coming from OPV components during their use phase. ► OPV components may enter the environment upon improper disposal, thus a recycling policy should be developed.
