Abstract
Efficient hybrid solar cells fabricated from TiO2, novel carboxylated polythiophene poly (3-thiophenemalonic acid) P3TMA as sensitizer
as well as hole conductor and poly (3-hexylthiophene) (P3HT) as hole transporter was described. UV–Vis absorption and morphology
of the active layer were investigated. Device J/V characterizations with different P3HT layer thickness were measured and
discussed. Efficiency improvements were observed in thinner P3HT layer thickness and with poly[3,4-(ethylenedioxy)-thiophene]:
poly(styrene sulfonate) (PEDOT:PSS) as charge collection layer, and such device showed a short-circuit current density of
1.32 mA/cm2, an open-circuit voltage of 0.44 V, a fill factor of 0.43, and a energy conversion efficiency of 0.25% at A.M. 1.5 solar illumination
(100 mW/cm2).
