Sol–gel preparation method usually used to prepare the metal oxides. So, it is a rewarding process to prepare the electron selective film made of aluminum-doped titanium dioxide (Al-doped TiO2). The latter was used to fabricate the inverted organic solar cells P2HT:PCBM. The doping content with Al impact on the optical and morphological characteristics of each film were examined. These characteristics were analyzed depending on the magnified images of the prepared samples by atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD) in addition to the Uv-vis spectroscopic results. The outcomes revealed that the concentration of Al doping has potential influences on the optical properties, XRD results and surface morphology. The J–V curve characteristics of each solar cell utilizing Al–TiO2 film were analyzed and noticed that the most powerful conservation efficiency is 2.09% when using Al–TiO2 layer with 0.5 wt.% Al as a doping element.

Efficient Power

Smart home uses a combination of the renewable energy power resources, the use of power generation from solar cells based on titanium dioxide (TiO2) which acts as the only type which produces an efficient solar cell power to obtain the electricity to recharge the standby storage device from the sunlight. The thin film of Titanium dioxide is synthesized by the sol-gel spin coating techniques at 2000 rpm on the glass. The films have a constant thickness of ~240nm. The annealing process consists of 150°C, 250°C and 350°C. The study of the absorbance and the wavelength values are important. At this condition, for the solar cell, the wavelength is around ~280nm to ~330nm. As the temperature of annealing increases the higher absorbance would be produced. The refractive index of TiO2 film is estimated at different annealing temperatures and it increases with the increasing of the annealing temperature. The application is suitable to smart home design. The dynamic output voltage obtained from the solar cells is interfaced with other circuitry such as inverters and interface charging circuit in order to inject the generated power into the standby storage device. The calculated result of this application is efficient to reduce the electrical bill by almost 30% of its original value.
