The photovoltaic property of Rhodamine B dye embedded into Poly(tolyl‐1,1′‐binaphthyl carbamate) (PU 1 ) and poly(hexamethylene‐1,1′‐binaphthyl carbamate) (PU 2 ) matrices have been evaluated using host‐guest approach. The photoactive layer comprising photoluminescent polymer matrix (PU 1 or PU 2 ), Rhodamine B and TiO 2 nanoparticles were prepared by spin casting method. The power conversion efficiency (PCE) the photovoltaic devices based on PU 1 and PU 2 matrices were found to be 0.043% and 0.029%, respectively. PCE of the photovoltaic devices were limited due to low lying highest occupied molecular orbital of PU 1 and PU 2 polymers. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011.
