A New Architecture for Printable Photovoltaics Overcoming Conventional Module Limits

Abstract

A new architecture for manufacturing large-area polymer solar cells that does not produce concomitant aperture and Ohmic losses is presented. By introducing the innovative concept of metal-filamentary nanoelectrodes, which are vertically formed inside the main active layers, loss-free, widely expandable solar cells with the highest relative power conversion efficiency (ca. 90%) in organic photovoltaic systems are demonstrated. © 2013 WILEY-VCH Verlag GmbH & Co.
