Abstract

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 it into electric current. The purpose of this study is to determine the potential of natural dye from red dragon fruit waste as a dye sensitizer. Red dragon fruit peel is initially extracted using methanol and the solution absorption spectra then is characterized using UV-Vis spectrophotometer. The absorption spectra is measured within a wavelength range of 400-800 nm. The characterization results show that the maximum absorption spectrum is at a wavelength of 446 nm. The natural dye solution then is used to immerse Fluorine Tin Oxide (FTO) coated with titanium dioxide (TiO2). The glass FTO is immersed in the dye solution for 24 hours. DSSC then is prepared by sandwiching the working electrode and counter electrode. An electrolyte solution is used to fill the interface between the two electrodes. The current and voltage (I-V) characteristics of DSSC is finally measured using amperemeter and voltmeter. The results indicated that the natural dye from the peel of red dragon fruit has potential as a dye sensitizer. Further research is still required to improve the performance of the DSSC.

Abstract

Indonesia plans to build solar PV plants to reach 6500 MW capacity by 2025. One of the solar PV applications is systems with battery storage systems. In this system, the battery is an important component of the solar PV system as it stores the energy for use when the sun is unavailable. This article reviews the status of batteries in Indonesia to support the proliferation of solar PV applications. The objective is to compile a battery database for solar PV applications. The database provides insight into technology and the availability of batteries. The database consists of 361 batteries of various technologies such as FLA, VRLA, VRLA gel, VRLA AGM, and Lithium-ion. The most widely available is the VRLA gel. In terms of voltage, batteries are available at 2 to 12 volts and with capacity from 1 to 3000 Ah. The availability of batteries shows that this field is ready to support the development of solar PV with energy storage although the field of battery recycling or its waste management requires more attention.
