We show that lifetimes exceeding 1250 h, even at high temperature/high humidity conditions, may be reached, proving that organic solar cells are significantly less sensitive against the environmental effects of water and oxygen than previously expected.||ISSN:||1077-3118||DOI:||10.1063/1.2975185||Rights:||© American Institute of Physics||Type:||Article||Affiliation :||Konarka Technologies
