Inkjet printing of back electrodes for inverted polymer solar cells

Angmo, D. (author), Sweelssen, J. (author), Andriessen, H.A.J.M. (author), Galagan, Y.O. (author), Krebs, F.C. (author)

Evaporation is the most commonly used deposition method in the processing of back electrodes in polymer solar cells used in scientifi c studies. However, vacuum-based methods such as evaporation are uneconomical in the upscaling of polymer solar cells as they are throughput limiting steps in an otherwise fast roll-to-roll production line. In...

Analysis of light intensity dependence of organic photovoltaics: Towards efficient large-area solar cells

Galagan, Y.O. (author), Manor, A. (author), Andriessen, H.A.J.M. (author), Katz, E.A. (author)

Large-area organic solar cells are known to suffer from a major efficiency decrease which originates from the combination of a voltage drop across the front electrode and the voltage-dependent photocurrent. In this letter, we demonstrate this efficiency loss on large area, indium tin oxide free cells with a hexagonal current collecting front...
