Large area,mini-modules and tandem organic solar cells: limitations in device area and high efficiency alternative polymers

Ikerne Etxebarria. Tutor Ikerlan: Roberto Pacios


Analysis of the limitation in device area for P3HT:PCBM based organic solar cells and posterior comparison with mini-modules of similar active area. A roll-to-toll compatible novel patterning technique based on surface modification was also developed for the patterning of the active layer. In order to achieve high efficiency devices, alternative polymers were also tested and optimized in photovoltaic devices. Finally, materials with complementary absorption spectra were stacked together in tandem cells and the performance of devices connected in series and parallel was studied.
