Impact of thermal and solvent vapor annealing in blend morphology of organic solar cells based on small molecules (Conference Presentation)

We have used two unsymmetrical small molecules with a D–A–D–π–D configuration as small molecule donors, along with PC71BM as an acceptor, for solution processed bulk heterojunction solar cells.
