We take the effort of developing low ecological harmful solvent processing of OPV devices and mini-modules, to strengthen the environmental benefits of OPV. New formula utilizing safer solvents enhanced with additives affords an optimal laboratory device efficiency of 20% as well as superior operational and thermal stability. Mini-module shows an efficiency up to 17.6% in upscaled processing, representing the highest performance for green solvent OPV development. Suitable nanoscaled phase separation is obtained in together with a micron-scale surface wrinkle pattern from the new developed processing strategy. Thus efficient photon-to-electron conversion at nano-interfaces and light extraction in broader receiving angles is achieved, which allows for more flexible installation geometries in building-integrated applications.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.146</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:p3-qv</dc:identifier> <dc:identifier>mcid:2024.146</dc:identifier> <dc:identifier>oai:materialscloud.org:2356</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>organic solar cells</dc:subject> <dc:subject>sustainability</dc:subject> <dc:subject>long-term lifetime</dc:subject> <dc:title>Organic solar cells with eco-friendly preparation to achieve an efficiency of 20%</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
