ScholarBank@NUS Repository. https://doi.org/10.1021/am201842n | Abstract: | High-performance plastic dye-sensitized solar cells (DSCs) based on low-cost commercial Degussa P25 TiO 2 and organic indoline dye D149 have been fabricated using electrophoretic deposition (EPD) with compression post-treatment at room temperature. The pressed EPD electrode outperformed the sintered EPD electrode and as-prepared EPD electrode in short-circuit current density and power conversion efficiency. About 150% and 180% enhancement in power conversion efficiency have been achieved in DSC devices with sintering and compression post-treatment as compared to the as-prepared electrode, respectively. Several characterizations including intensity modulated photocurrent spectroscopy, incident photon-to-electron conversion efficiency and electrochemical impedance spectra have been employed to reveal the nature of improvement with post-treatment. Experimental results indicate that the sintering and compression post-treatment are beneficial to improve the electron transport and thus lead to the enhancement of photocurrent and power conversion efficiency. In addition, the compression post-treatment is more efficient than sintering post-treatment in improving interparticle connection in the as-prepared EPD electrode. Under optimized conditions, the conversion efficiency of plastic devices with D149-sensitized P25 TiO 2 photoanode has reached 5.76% under illumination of AM 1.5G (100 mW cm -2). This study demonstrates that the EPD combined with compression post-treatment provides a way to fabricate highly efficient plastic photovoltaic devices. © 2012 American Chemical Society. | Source Title: | ACS Applied Materials and Interfaces | URI: | http://scholarbank.nus.edu.sg/handle/10635/89117 | ISSN: | 19448244 | DOI: | 10.1021/am201842n |
