In2S3 – a wide-gap semiconductor – has been implemented in organic photovoltaics using an all-solution based sol–gel route. Typically, indium sulfide is deployed as a buffer layer in copper–indium sulfide (CIS) photovoltaic systems as electron-selective contact on the bottom electrode. We transferred this idea to organic, solution-processed photovoltaics, exploring its potential in an inverted hybrid...
Postproduction treatment of poly (3-alkylthiophene) based bulk-heterojunction solar cells is an important and required procedure in order to fabricate organic solar cells with highest power conversion efficiencies. Postproduction treatment, by means of annealing solar cells at elevated temperatures during which an external voltage is simultaneously applied, is not very suitable for large scale production...
