The starch based biocompu00f3sito added TiO2 and argilosilicato for application in photovoltaic cell

摘要

The present invention relates to a new material obtained from renewable sources and characteristics for application in solar cells.A solar cell is a device that operates based on photovoltaic effect, which consists in the direct conversion of an electromagnetic radiation into electrical energy.The addition of plasticizers.Particles of titanium oxide (Ti02) and montmorilonite clay (MMT) improve the thermo physical properties of biocompu00f3sitos of starch with potential for application in solar cells.The addition of MMT influence directly the thermal stability and to increase the rigidity of the biocompu00f3sitos. Analyses on refletu00e2ncia diffuse provided data of absorbance and refletu00e2ncia.The curves of absorption obtained provided the value of EG AP to the biocompu00f3sitos, parameter that is important for the process fotocatalu00edtico,We showed that with the addition of Ti02 and MMT the forbidden interval of energies is smaller and thus increased the potential fotocatalu00edtico material.Since this would require less energy to be activated.The results of refletu00e2ncia diffuse also showed that biocompu00f3sitos with conductive or photoconductive characteristics can be obtained from these materials and suitable for application in cells.Solar.
