The application of nature dyes was explored for solar cells due to several advantages for green technology. These can be supporting in renewable energy alternatives, which must include solar energy. This system was fabricated as hybrid solar cells, which consist of organic and non-organic materials. Metal oxide semiconductor (MOS), TiO2, was selected as charge separation and transport. Bixa orellana used as extracted natural dyes solution in order to enhance the absorption of photons. The dyes were extracted by using immerging in methanol solution and left until dyes being extracted. The dyes were coated on ITO glass by using Electrochemical Impedance Spectroscopy (EIS) varied by 1, 3, 5, 7 and 10 layers of scan. This work focuses on conductivity and charge carrier study of thin film. The result shows the conductivity was increase due to several parameters that are, thickness of thin films, and intensity of light, mixture of natural dyes and concentration of dyes solution. The conductivity was then supported with the energy band gap via UV-Vis Spectroscopy.

High efficiency solar cells require large surface layers as acceptor [1], Nanoporous titanium dioxide film is an optimun choice for that purpose. For instance, porous titanium dioxide film of one micrometer thickness, prepared by colloidal chemistry, has a porous surface whose area is 100 times larger than the surface of a compact planar film. Obviously, accessibility to surface and crystal phase of the titanium dioxide are of prime importance. In this work, we characterize nanoporous titanium dioxide membranes on Si substrate by means of high-resolution transmission electron microscopy and electron diffraction.Colloidal TiO2 sols were prepared by a wet chemical method [2]. The resulting colloidal TiO2 sol was autoclaved in a titanium autoclave for 12h at 230°C. A portion of the autoclaved sol was concentrated under vacuum at 30°C until a concentration of 20% TiO2 (by weight) was reached. 40% (by weight of Ti02) carbowax was added to this paste and stirred over night at room temperature.
