Banerji, Natalie 2016-08-24 Organic solar cells consist of thin films combining an electron donor (often a conjugated polymer) with an electron acceptor (often a fullerene derivative), in a blend commonly referred to as bulk heterojunction material. Charge separation between the donor and the acceptor leads to the generation of carriers, which can be extracted from photovoltaic devices in the form of photocurrent. The generation mechanism of free, extractable charges has caused a lot of controversial discussion in literature. Our research has shown that all the steps involved in charge generation are strongly dependent on the arrangement of the donor and the acceptor (i.e. the structure) of the bulk heterojunction. application/pdf https://folia.unifr.ch/global/documents/304971 https://folia.unifr.ch/documents/304971/files/ban_spr.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.2533/chimia.2016.512 info:eu-repo/semantics/openAccess License undefined CHIMIA International Journal for Chemistry. - 2016, vol. 70, no. 7, p. 512–517 info:eu-repo/classification/udc/54 Structure–Property Relations in Polymer:Fullerene Blends for Organic Solar Cells http://purl.org/coar/resource_type/c_6501
