What is it about?
Dye-sensitized solar cells (DSSCs) which utilize dye extracted from local red dragon fruit’s flesh were hand fabricated. The fabricated samples were tested using an own-made solar simulator with 85 W 12 V halogen light source and measured for I-V curve using a home-made Arduino-based automated I-V measurement tool. The results show that a cell of 21 mm x 21 mm has open circuit voltage (Voc) of 459.28 mV, short circuit current (Isc) of 10.14μA, fill factor (FF) of 55.39% and conversion efficiency (η) at maximum power point (MPP) of 0.0088% at 30 minutes post assembling under exposure to 66.7 W/m2 irradiation. The DSSC degraded over time and fitted well to a two-parameter model equation.
