Abstract

Anthocyanin is a type of natural pigment that gives color to plants and can be used to absorb visible light with wavelength of 400-600 nm. The absorption ability is very useful for dye in designing dye sensitized solar cell (DSSC). The anthocyanin can be extracted from blueberry and has unique characteristic of high stability when it reaches low pH. In this paper, design of DSSC with dye made of blueberry anthocyanin and its performance related to pH variation is presented. The performance was evaluated experimentally according to output voltage and current generated by 4 fabricated samples (pH of 1.5, 2, 2.6, 4.4) from A.M 1.5 sunlight and 10-watt LED. Experiment results show that for both light sources, dye with pH of 1.5 has the highest output voltage and current among the others. Since the output voltage and current are very small, the exsisting design of DSSC is suitable to be developed for optical sensor.

Highlights

The world is depending energy source mainly from non renewable sources, such as fossil fuel and coal, which time by time is being decreasing [1,2,3,4]
The Dye Sensitized Solar Cell (DSSC) was basically imitated the process of photosynthesis to catch the solar energy and convert the photon into electrical energy [13, 14]
The experiments are related to dye absorbance, output voltage and current with light sources of AM 1.5 sunlight and 10 watt LED

Summary

Introduction

The world is depending energy source mainly from non renewable sources, such as fossil fuel and coal, which time by time is being decreasing [1,2,3,4]. Solar energy is converted into electrical energy through a process called photovoltaic effect [8, 9]. The DSSC was basically imitated the process of photosynthesis to catch the solar energy (photon) and convert the photon into electrical energy [13, 14]. Among all of the parts, dye performs most important role in absorbing and converting light to electrical energy [17, 18]. The DSSC performance is highly depends on the dye used as sensitizer [19]
