Perovskite material ( MAPbI3<\/sub> ) solar cells were used because of their capability to respond to light. The transient response characteristics of MAPbI3<\/sub> perovskite-based solar cell devices with and without SnO2<\/sub> layer were investigated in this paper. Under the illumination of red, green, and blue light sources, the capacitance measurement was carried out with a variation of series resistor with solar cell devices. To ensure statistical robustness, five identical devices were fabricated and tested for each configuration, and the average values were reported. MAPbI3<\/sub> perovskite devices with SnO2<\/sub> layer show fast responsiveness to variations in light intensity with response time ( \u03c4 ) reduces from 25.7 ms to 13.4 ms that is attributed to the enhanced electric field increases and accelerated accumulation charge. The peak of output voltage ( Vout,max<\/sub> ) increases in the dark condition from 0.32 V to 0.53 V , revealing that the SnO2<\/sub> layer functions as an electron transport layer with a sufficiently wide band gap to facilitate charge separation and accumulation at the electrodes. The highest output voltage of a perovskite solar cell with the SnO2<\/sub> layer occurs under the illumination of the red light source due to its low-energy photons that allow electron to be excited from valence band to conduction band, thus absorbing photons at high wavelengths. Furthermore, the capacitance ( C ) of devices with the SnO2<\/sub> layer decreased from 2.573\u00b5 F to 1.342\u00b5 F compared to those without the layer. These findings demonstrate that transient response characteristics enable perovskite solar cells with SnO2 layers to function as effective photo-capacitive sensors.<\/p>\n\n\n\n
