Making Dye Solar Cells with Natural Extracts of Cabbage and Rubia Tinctorum and the Comparison of their Characteristics

Abstract

One of the key components of dye solar cell is a pigment. The most important characteristics of a pigment is wide range of absorption spectrum, and its more photonic absorption. This article reports the characteristics of a dye solar cell with pigments obtained from extracts of cabbage and rubia tinctorum on nanoparticles. Regarding the results of spectrophotometry, the scope and extent of absorption of these two pigments is relatively high. The results of the measurements for each square centimeter of produced cells via the declined radiation of Sun light in intensity of (90 mW/cm2) are as follows:

A dye solar cell with extract of cabbage: Jsc(µA/cm2=4360   Voc(mv)=400.4  µ=0.9%

A dye solar cell with extract of ronas: Jsc(µA/cm2=3110   Voc(mv)=399  µ=0.42%

According to the simple method of production and low cost of these cells, compared to other imported ones, there is a great hope to its spread for the optimization of these features.
