This research paper aims to present a concise, depth insight of organic solar cells. Subsequently, this paper also discusses various recent advancements in organic solar cells in terms of material, structures and other performance influencing factors. This paper reviewed to see the effect of TiO2 nano particles on η in the BHJ polymeric solar cell by its incorporation into the composite active (photovoltaic) layer, comprised of poly3-hexyl-thiophene P3HT, and [6,6]-phenylC61-butyricacid-methylester (PCBM). Nano-structured TiO2 exhibits good processability, favourable characteristics of the transport of electrons, and brilliant physical as well as chemical stability which are important wants in solar cells as impact of blending of TiO2 nano particles in between photo-active layers is elucidated the electrical performance of P3HT-PCBM-based solar cells. This paper relates to bulk heterojunction organic solar cells. More specifically, the enhancement of PCE of solar cell based on polymer, using mix of poly 3-hexylthio-phene(P3HT), derivatives of C60as [6, 6]-phenyl C61butyric-acidmethylester (PCBM) and TiO2 nano particles has been reported. P3HT-TiO2 based solar cell has also been fabricated as there is a probability of improvement in η and JSC by optimizing the blending concentration of TiO2 nano particles.
