Experimental elaboration and analysis of various dye-sensitized solar cells (DSSCs) and hybrid solar cells

Hybrid and organic solar cells have attracted the attention of optoelectronics engineers and interdisciplinary scientists. Nowadays main scientific works on organic photovoltaics are focused in efficiency increasing and finding novel materials and technology for overall improvements. On the market, there are plenty conventional solar cells such as silicon solar cells or cells based on compounds like Cadmium Tellurium (CdTe) or Sulphur Tellurium (CdS), which are the most widespread and utilized by scientist and end-users, although these solutions are high cost in the process of manufacturing and implementation on the market, so they still do not represent competition for energy sources based on fossil fuels.
In this paper we propose low cost and easy in development, fully working dye-sensitized solar cell module (Fig 1.) made with use of a different sensitizing dyes (anthocyanins for DSSC and conductive polymers like P3HT for hybrid-cells), semi-transparent condictive substrates (vaccum spattered gold), nanometer sized TiO2 film, iodide or Viologen electrolyte, and a counter electrode (vaccum spattered platinum or carbon). Moreover, some of the different technologies, such as adding a thin layer of nanoparticles of graphite oxide or optimization of manufacturing processes, were elaborated for energy efficiency increase and were presented in this project.
