Conjugated polymer:TiO2 nanocomposite solar cells based on P3HT nanoparticles.

Subject

Nanocomposites; Solar cells (fabrication and characteristics of conjugated polymer:titania nanocomposite solar cells based on poly(3-hexylthiophene) nanoparticles)

Description

There is widespread interest in developing efficient solar cells derived from conjugated polymers and TiO2. The conjugated polymer can act as a light harvesting dye as well as a hole transport material, and can potentially replace both the ruthenium dye and the I3-/I- couple in the dye-sensitized solar cells. Herein, we report a novel and facile approach of using conjugated polymer nanoparticles to make conjugated polymer:TiO2 nanocomposite based solar cell. Nanoparticles from poly(3-hexylthiophene) (P3HT) were made using mini-emulsion technique. In this work we report on incorporation of these P3HT nanoparticles into nanoporous titania. Device characteristics made using P3HT nanoparticle sensitized solar cells were measured. These devices showed a short-circuit c.d. of 0.207 mA/cm2, open-circuit voltage of 0.62 V, and efficiency 0.07%. [on SciFinder(R)]
