Abstract: Dye-sensitized solar cell (DSSC) has low power output and efficiency. Even though the low-concentrated light can increase the POUT and power conversion efficiency (PCE) of DSSC, the effect of increase in the cell temperature, particularly electrolyte evaporation, becomes a major concern. In this study, we compared and investigated the performance of acetonitrile (AN-50), propionitrile (PN-50), and 3-metoxy propionitrile (Z-100) as nitrile-based electrolyte under low-concentrated light. The results showed 4–8 times increase in JSC and POUT in all electrolytes. AN-50 demonstrated an improved performance under influence of 2 cm distance concave mirror concentrated light with the highest JSC = 74.21 mA/cm2, POUT = 24.53 mW/cm2, and η = 7.99. However, the performance of cell with AN-50 and PN-50 started to degrade within 3 h of measurement. In contrast, Z-100 displayed performance stability during 4 days measurement even with the lowest JSC= 49.98 mA/cm2, POUT = 19.50 mW/cm2, and η = 6.35.
