Issue Date: | 2011 | Publisher: | ACS | Source: | JOURNAL OF PHYSICAL CHEMISTRY C, 115. p. 16695-16700 | Abstract: | This paper focuses on the characterization of the ZnO/poly(3-hexylthiophene) (P3HT) interfaces in nanostructured hybrid solar cells, aiming to elucidate the relationship between thermal treatment, local morphology, and device performance. An equivalent impedimetric model for the device is proposed, allowing us to extract information about the ZnO/P3HT interface morphology and its impact on the photovoltaic properties by comparing devices with and without nanopatterning. It is found that the influence of thermal treatment on performance lies solely in the interface, resulting from a different interfacial morphology of P3HT depending on which crystal direction of ZnO is present. | Document URI: | http://hdl.handle.net/1942/12239 | ISSN: | 1932-7447 | e-ISSN: | 1932-7455 | DOI: | 10.1021/jp203699h | ISI #: | 000294077000058 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2012 |
