Nanostructured Cathode Buffer Layers for Inverted Polymer Solar Cells

摘要: Polymer solar cells (PSCs) based on polymer donor-fullerene derivative acceptor bulk heterojunction (BHJ) active layer have attracted considerable attention as a promising alternative to conventional silicon-based due their cost effectiveness, compatible with flexible substrate and solution-based roll-to-roll processing technique. Inverted PSC seems be the best candidate that meets requirements for both high efficiency good stability. To achieve power conversion (PCE) in inverted PSCs, selection of an appropriate nanostructured cathode buffer (CBL) so optimize electron collection transport is particularly important. Nanostructured zinc oxide (ZnO) CBLs been most extensively studied PSCs view its relatively mobility, optical transparency, ease being synthesized low solution methods at temperature, versatile morphologies, environmentally stable. This chapter focuses design, fabrication characterization constructed pristine ZnO, doped-ZnO, ZnO-based composites well surface modified improvement PCE long-term device stability PSCs.
