An urgent task in the field of sensitized solar cells (DSSC) is to decrease the temperature of thermal annealing of titanium dioxide photoanode. In this work, we use a titania based polymer as organic “polylinker,” which allows low temperature annealing. This polylinker, which is obtained by means of partial hydrolysis of titanium polybutyltitanate or tianium 2-methoxyethoxide allowed us to decrease the annealing temperature of titanium dioxide down to 150–180°C. This permits the manufacture of DSSC on flexible polymer substrates. DSSC samples with efficiency of energy conversion up to 1% are obtained.
