Photovoltaic device characteristics before and after annealing were measured under air mass 1.5 simulated solar illumination (100 mW/cm 2). Annealing times up to ∼15 min resulted in a sharp increase in short circuit current density and power conversion efficiency, with more gradual improvements upon further annealing. This performance improvement is attributed partly to enhanced optical absorption and partly to improved charge collection, which may result from enhanced charge carrier mobilities | URI: | https://hdl.handle.net/20.500.14279/1442 | ISSN: | 03796779 | DOI: | 10.1016/j.synthmet.2005.07.189 | Rights: | © Elsevier | Type: | Article | Affiliation: | Imperial College London | Affiliation: | Imperial College London | Publication Type: | Peer Reviewed |
