In an effort to contribute to the development of new alternative energy technologies, in the present study it has been investigated on a laboratory scale the behavior of Dye Sensitized Solar Cells (DSSC’s) using a variety of electrolytes and an optimized asymmetric squaraine tint (SQ2). The analysed electrolytes were: Biodegradable viscous unpatented electrolyte (EBNP-V), Biodegradable unpatented liquid electrolyte (EBNP-L), Iodide/Tri-iodide electrolyte (EI-/I3-) and Biodegradable Iodide/Tri-iodide electrolyte (EB I-/I3-). These were characterized through electro-chemical testing of cyclic voltammetry, charge and discharge and an inductance, capacitance and resistance (LCR) measurer in order to meet its electrochemical properties and its influence over cells. The DSSC’s were constructed with the electrolytes listed previously and the efficiency photovoltaic parameters (ƞ), open circuit voltage (Voc), short circuit current (Isc) y fill factor (FF) were characterized.
By statistical tests, the EBI-/I3- comes as the most influential electrolyte in the photovoltaic performance parameters of the cells, it was prepared with a biodegradable solvent. Additionally, favorable results were obtained by complementing EI-/I3- with EBNP-L at low concentrations, this contributes to the develop new research to look for a biodegradable and low cost electrolyte which contributes to a better performance of the DSSC. |
