One of the problems encountered in the making of dye-sensitized solar cell (DSSC) is the efficiency still relatively small compared to the conventional solar cells made from silicon. In this study, microwave irradiation was used in the process of coating Musa Accuminata Bract extract, with the aim that more anthocyanin pigments absorbed in the work electrode. This anthocyanin can make more sun energy absorbed and enhances efficiency. The resulting Musa Acuminata Bract extract was characterized using Ocean Optic Vis-Nir USB 4000 to determine its optical properties and produce maximum absorbance of 1.7353 at mass fraction of 0.45. The irradiation process was carried out using Electrolux Microwave Oven (EMM 2308X) at 140 W. After the DSSC sandwich is arranged, the sample is characterized using an El-Kahfi 100 I-V meter to determine its electrical properties. DSSC without microwave irradiation has an efficiency of 0.000345%, while with microwave irradiation, it could yield efficiency of 7.26%. This proves that microwave irradiation can improve DSSC performance. © Published under licence by IOP Publishing Ltd.
