Role of temperature in the recombination reaction on dye-sensitized solar cells.

摘要: The performance of photovoltaic (PV) devices as a function temperature is crucial for technical development and accurate commercial information. Along with solar irradiance, the most important operating factor PV device performance. Normally, it widely accepted that dye sensitized cells (DSC) show minimal energy efficiency dependence (20-60 °C). in DSCs depends on light absorption, charge transport (ohmic resistances) recombination rates. In this study, reaction kinetics was studied within wide range. A unique laser assisted sealing technique allows studying effect between -5 °C 105 without electrolyte leakage or external contamination used. To best our knowledge, highest ever considered kinetic studies liquid state DSCs. electrochemical electrons triiodide/iodide ions shown to be determining temperature. It concluded activation reactions interface where happens - TiO2/electrolyte SnO2-F/electrolyte found addition having deep influence rate, injecting electron also critical. These conclusions should provide solid ground further developments perovskite cells, allow better comparison different technologies over range temperatures.
