Maximized performance of dye solar cells on plastic: a combined theoretical and experimental optimization approach

摘要

We demonstrate that a combined optimization approach based on the sequential alternation of theoretical\udanalysis and experimental realization gives rise to plastic supported dye solar cells for which both light\udharvesting efficiency and electron collection are maximized. Rationalized configurations with optimized light\udtrapping and charge extraction are realized to achieve photoanodes on plastic prepared at low temperature,\udshowing a power conversion efficiency of 8.55% and a short circuit photocurrent of 16.11 mA cm 2,\udunprecedented for plastic based dye solar cell devices. Furthermore, the corresponding fully flexible designs\udpresent stable mechanical properties after several bending cycles, displaying 7.79% power conversion\udefficiency, an average broadband internal quantum efficiency above 90%, and a short circuit photocurrent\udof 15.94 mA cm 2, which is the largest reported value for bendable cells of this sort to date
