Semiconducting polymer-incorporated nanocrystalline TiO2 particles for photovoltaic applications

► A P3HT-PCBM/TiO2 trinary hybrid solar cell has been fabricated. ► P3HT-PCBM heterojunction replaces the dye and electrolyte in dye-sensitized cell, ► Which simplifies preparation procedure and decreases the device cost. ► The hybrid cell achieves a light-to-electric conversion efficiency of 2.61%.
