TiO2-Based Organic Hybrid Solar Cells withMn+2Doping

摘要

A hybrid solar cell is designed and proposed as a feasible and reasonable alternative, according to acquired efficiency with the employment of TiO2(titanium dioxide) and Mn-doped TiO2thin films. In the scope of this work, TiO2(titanium dioxide) and Mn:TiO2hybrid organic thin films are proposed as charge transporter layer in polymer solar cells. Poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester (P3HT: PCBM) is used as active layer. When the Mn-doped TiO2solar cells were compared with pure TiO2cells, Mn-doped samples revealed a noteworthy efficiency enhancement with respect to undoped-TiO2-based cells. The highest conversion efficiency was obtained to be 2.44% at the ratio of 3.5% (wt/wt) Mn doping.
