  2. 1. Solution Chemistry and Morphological Properties for Organic Solar Cells : Exploring Alternative Solvents Using Microgravity and Modelling as Tools

    Author : Ishita Jalan; Jan van Stam; Patricia Saenz Mendez; Stela Andrea Muntean; Mariano Campoy-Quiles; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solution chemistry; green solvents; microgravity; OPV; HSP; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Abstract : Organic photovoltaics (OPVs) have the advantage of the accessibility of energy for all, due to facile and low-cost processing, with its low energy payback time compared to other technologies, therefore promising applications. Research and development have led to power conversion efficiencies of nearly 20% and now catching up to their inorganic counterparts. READ MORE
