摘要

Temperature and humidity are the two critical external parameters that substantially influence the efficiency of dye-sensitized solar cells (DSSCs). The performance of DSSCs is reliant upon several factors, including electrolyte characteristics, the dye applied on the semiconductor, and charge separation. Temperature and humidity may impact DSSCs in various ways in terms of their structural and mechanistic quality, hence affecting their performance. This work involved the testing of DSSCs under diverse temperature and humidity settings. The power conversion efficiency (PCE) of the DSSCs was notably reduced by about 28% when the temperature rose from 25°C to 60°C and by about 39% when both temperature and humidity were elevated simultaneously from 25°C to 60°C and from 75% to 100%, respectively. Elevated temperatures and humidity circumstances may result in dye degradation and desorption from the semiconductor, electrolyte degradation, and an increase in charge recombination, finally affecting the JSC and diminishing the device’s overall performance. This study will facilitate potential commercialization of DSSCs in actual weather circumstances.
