Abstract
Light-harvesting layers in organic bulk-heterojunction solar cells are commonly fabricated from aromatic or even chlorinated solvents, which are often toxic or otherwise hazardous. In this work, nanoparticle dispersions of a blend of poly(3-hexylthiophene) and [6,6]-phenyl C71-butric acid methyl ester (P3HT:PC71BM) are synthesized in water, omitting any stabilizing surfactants which would remain in the layer and hamper the device performance. To overcome wetting issues and to master the deposition of thin films from aqueous dispersions, co-solvents are employed. The solar cells exhibit power conversion efficiencies of 2.7% and show excellent long-term stability, paving a promising way towards the all-eco-friendly production of organic solar cells in the future.
期刊介绍：
Energy Technology provides a forum for researchers and engineers from all relevant disciplines concerned with the generation, conversion, storage, and distribution of energy.
This new journal shall publish articles covering all technical aspects of energy process engineering from different perspectives, e.g.,
new concepts of energy generation and conversion;
design, operation, control, and optimization of processes for energy generation (e.g., carbon capture) and conversion of energy carriers;
improvement of existing processes;
combination of single components to systems for energy generation;
design of systems for energy storage;
production processes of fuels, e.g., hydrogen, electricity, petroleum, biobased fuels;
concepts and design of devices for energy distribution.
