Nanoscale mapping by electron energy-loss spectroscopy reveals evolution of organic solar cell contact selectivity
Guerrero, Antonio; Pfannmöller, Martin; Kovalenko, Alexander; Ripollés Sanchis, Teresa; Heidari, Hamed; Bals, Sara; Kaufmann, Louis-Dominique; Bisquert, Juan; Garcia-Belmonte, Germà Elsevier (2015)Organic photovoltaic (OPV) devices are on the verge of commercialization being long-term stability a key challenge. Morphology evolution during lifetime has been suggested to be one of the main pathways accounting for ... -
Shelf Life Degradation of Bulk Heterojunction Solar Cells: Intrinsic Evolution of Charge Transfer Complex
Guerrero, Antonio; Heidari, Hamed; Ripollés Sanchis, Teresa; Kovalenko, Alexander; Pfannmöller, Martin; Bals, Sara; Kaufmann, Louis-Dominique; Bisquert, Juan; Garcia-Belmonte, Germà Wiley (2015)Achievement of long-term stability of organic photovoltaics is currently one of the major topics for this technology to reach maturity. Most of the techniques used to reveal degradation pathways are destructive and/or do ... -
Toward High-Temperature Stability of PTB7-Based Bulk Heterojunction Solar Cells: Impact of Fullerene Size and Solvent Additive
Dkhil, Sadok Ben; Pfannmöller, Martin; Saba, Maria Ilenia; Gaceur, Meriem; Heidari, Hamed; Videlot-Ackermann, Christine; Margeat, Olivier; Guerrero, Antonio; Bisquert, Juan; Garcia-Belmonte, Germà; Mattoni, Alessandro; Bals, Sara; Ackermann, Jörg Wiley (2017-02)The use of fullerene as acceptor limits the thermal stability of organic solar cells at high temperatures as their diffusion inside the donor leads to phase separation via Ostwald ripening. Here it is reported that ...
