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 TiO 2 dye‐sensitized solar cells through standard operations, showing strong absorption bands at around 320–650 nm, and exhibiting broad IPCE responses. Cell based on XS17 gave a J sc of 3.7 mA/cm 2 , 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 V oc values, which mainly stem from the acceptor of rhodanine‐3‐acetic acid.
