主 题:dye-sensitized solar cell photovoltaic N,N-dimethylaryl amine organic dyes
摘 要:Three organic dyes XS17--19 based on N,N-dimethylaryl amine and rhodamine-3-acetic acid moieties are designed and synthesized. These dyes were applied into nanocrystalline TiOa dye-sensitized solar cells through standard operations, showing strong absorption bands at around 320--650 rim, and exhibiting broad IPCE responses. Cell based on XS17 gave a Jsc of 3.7 mA/cm2, an open circuit voltage of 550 mV, and a fill factor of 0.68, corresponding to an overall conversion efficiency of 1.4%. The low overall conversion efficiency is due to the modest IPCE and Voc values, which mainly stem from the acceptor of rhodanine-3-acetic acid.
