Dye-sensitized solar cell (DSSC) is one of the potential candidates for the next generation solar cells. One of the most attractive features of the DSSC is the low production costs. The utilization of natural dyes is a new area for investigation due to their unique capability to absorb photons from natural sunlight or artificial light and convert i...

... is used as sensitizers, the dye solution is characterized in advance using UV-Vis Spectrophotometer to identify the absorption power of extract of red dragon fruit peel upon visible wavelength. The absorption spectrum is calculated in the range of wavelength of 400-800 nm. The characterization result of absorption spectrum is such as what seen in Fig. 3. Extract of red dragon fruit peel is proved to have an absorption power on the wave of visible length, meaning that it is seen on the peak of absorption in the wavelength of 446 nm. The testing of DSSC energy conversion ability is conducted using 220 Volt, 500 Watt halogen source of light such as what can be seen in Fig. 4. DSSC is ...
