Study on hybrid structure on TiO2 nanorods and graphene enhanced P3HT for solar cells application

Abstract EN

Recently, hybrid structure graphene / organic nano composite have been studied for low cost photovoltaic devices (P3HT / Graphene ) can be formed by solution process at room temperature, in this study, we demonstrate a hybrid solar cells composite of (Graphene-P3HT / TiO2 Nanowire to allowed for distributed the organic materials among the nanorode, the organic which cover by spin coating to provide higher mobility and conductivity of (G-P3HT) where employed as P-type or Hole transparent materials with TiO2 NW as a photoanode.

The nanocoposite of P3HT (G-P3HT, 10 % wt graphene) deposited on TiO2 NW by spin couter technique.

The solar cells based on vertical TiO2 NW nanowire arrays by utilizing a spin couter spin speed.

The initial results showed the power conversion efficiency of 0.5 %.

The cells with G-P3HT showed different performance.

The power conversion efficiency was improved from 0.3 for spin couter speed 300 rpm to 1.3 at 500 rpm for G-P3HT among different spin speed solar cells.

It exhibited tunable power conversion efficiency with spin speed, with very thin materials and in expensive processing ,hybrid G/P3HT /Nanorod solar cells are promising as an economically viable alternative energy solution .
