In the field of flexible electronics, a great deal of effort is currently being focused on research into solar cells manufactured with organic materials and some very interesting results have been achieved. One of the primary limiting factors of these devices is the instability of the active layers, which can negatively affect electronic output and reduce efficiency.
The journal Advanced Functional Materials has published a study on the mechanisms involved in the degradation of organic solar cells, which was written by URV researchers Jairo Cesar Nolasco, Josep Pallarès and Lluís F. Marsal, of the NePhos research group and co-authored by Bernhard Ecker, Jörg Posdorfer, Jürgen Parisi and Elizabeth von Hauff, of the Energy and Semiconductor Research Laboratory at the Carl von Ossietzky University of Oldenburg, Germany.
The article examines the output of different solar cells in which the active layer is composed of a polymer mix (P3HT:PCBM). Specifically, the composition, solvents, electrical conductivity, and working function of the active layer were altered to test the resulting influence on the degradation of the cell. The article is the result of a three month pre-doctoral visit to the German university.
The "Nanoelectronics and Photonic Systems" (NePhoS) research group is part of the Research Centre for Engineering of Materials and Micro/Nanosystems (EMaS) and focuses its research in the field of electronic nanotechnology and photonics.
The journal Advanced Functional Materials has the sixth highest impact rating in the field of nanoscience and nanotechnology and publishes works on photovoltaic materials and devices, organic electronics, nanotechnology, photonics and biomaterials.
