Produção de Componentes de Células Fotovoltaicas Sensibilizadas de Baixo Custo de 3ª Geração

Dye-sensitized solar cells are a new option for cost and effiiency in clean energy production. Thus, the use of new sensitizers and new processing in the electrode components of these cells is necessary for further popularization. Thus, in this work we studied materials such as graphene oxide, TiO2 and anthocyanin-based sensitizers obtained by simple routes that showed good results. The structural and optical properties indicated that sensitized P25 and TiO 2 powders can be applied as photo anodes and graphene oxide as a counter electrode in low cost photovoltaic cells.
