“…In contrast, cells with an active surface area of 2 and 3 cm 2 at the same intensity result in a row voltage amounting to 719 mV and 1000 mV, which is almost two times and three times than that of the cell with the active surface area of 1 cm 2 . This is because the more significant the surface area of a solar cell, the more bixin electrons can be excited in the DSSC system, causing an increase in maximum voltage [21]. The active surface area variation of these cells also affects the Isc generated by DSSC cells.…”

Dye-Sensitized Solar Cells or DSSC is the latest solar cell type generation that uses natural dyes as sensitizers. Bixin extracted from the seeds of kesumba (Bixa orellana L) is one of the natural dyes that can be used as a sensitizer. This study aims to determine the effect of the active surface area of solar cells on the effectivity and reusability of bixin-sensitized solar cells based on their open-circuit voltage (Voc), short-circuit current (Isc), and maximum energy conversion efficiency. The results of this study will provide an overview of the best surface area to produce DSSC with the highest maximum energy conversion efficiency and the lifetime of bixin sensitized solar cells. The measurement results showed that the resulting Voc for each variation of the surface area 1, 2, and 3 cm2 was 344; 719; 1002 mV under intensity 100 mW cm-2, while the Isc produced under the same intensity was 0.223; 0.471; 0.680 mA. Based on the calculation results, the maximum power generated by each surface area was 0,077; 0,338; 0,681 W. This means that the larger the active surface area of the solar cell, the greater the voltage and current generated. In this work, the highest efficiency was produced by solar cells with a surface area of 2 cm2, which is 0.085%. The solar cells fabricated in this study can be reused for five days under continuous irradiation.

“…It is related to the increasing number of electrolytes that can occupy anodes to increase the number of electrons produced from each cell. The more electrons can improve, the intensity of electron transfers between the bixin and the electrolyte increases, causing the cell's maximum current [21].…”

Dye sensitized solar cell (DSSC) is made with a layer arrangement of fluorine tin oxide (FTO), zinc oxide (ZnO), dye, electrolyte, and plastisol. ZnO nanorods which play a role as photoanode in DSSC have been successfully grown on FTO substrate using seed mediated hydrothermal method at temperature of 90 ºC for 8 hours. Modification was made to increases the efficiency of DSSC by adding silver (Ag) with concentration of 5 mM into dye molecules. ZnO characterization was performed using ultra violet-vissible (UV-Vis) spectroscopy and field emission scanning electron microscopy (FESEM). The strongest UV-Vis absorbance spectrum with the optimum absorbance for the ZnO sampel was occurred at the wavelength range of 300 -360 nm. Meanwhile, for the ZnO sample with addition of 5 mM Ag into dye molecule was occurred at the wavelength range of 440 -530 nm. FESEM image of the sample shows the as-synthesized ZnO nanorods have hexagonal cross section. I-V characteristics in the light mode was carried out to determine the efficiency of DSSC using a halogen lamp with an intensity of 100 mW/cm 2 . The efficiency of DSSC using ZnO with addition of 5 mM Ag into dye molecule is 0.462%, increases compared to the efficiency of DSSC using ZnO without addition of Ag into dye molecule which only produce 0.45% efficiency. These results indicate that the addition of Ag can increase the efficiency of DSSC.

“…The use of solar energy can be used to generate electrical energy in solar cell applications (Bagher et al, 2015;Gaur & Tiwari, 2013). One type of widely studied solar cell is the Dye-Sensitized Solar Cell (DSSC), a third generation composed of dyes that can convert solar energy into electrical energy using photoelectrochemical principles (Gratzel., 2003;Nurhidayah, et al, 2019;Baryshnikov, et al, 2013). The DSSC consists of a working electrode, a semiconductor, a dyesensitized solar cell, an electrolyte, and a reference electrode (Yum, et al, 2010).…”

This study is an experimental study aimed at clarifying the characteristics of the solvent in the extraction of lycopene in tomato (Solanum lycopersicum) as a candidate photosensitizer for dye-sensitized solar cells (DSSC). The performance of DSSC depends on the type of dye commonly used as a sensitizer. Tomatoes contain an lycopene. Yields of lycopene extract in tomatoes were characterized by FTIR and UV-Vis spectrophotometers. The extraction methods used in this study are the maceration method and liquid-liquid extraction. The procedure of this study was carried out in two main stages, the extraction stage and the characterization stage. The first step was the extraction of lycopene from tomatoes using the maceration and liquid-liquid extraction methods. The maceration process compared the use of acetone and ethyl acetate as solvents. This extraction step produced 6.514 g (acetone) and 5.6702 g (ethyl acetate) lycopene extracts. The second step is to identify the functional groups of the compound formed using an FTIR spectrophotometer and use a UV-Vis spectrophotometer to determine the absorbance and maximum wavelength value of the lycopene and M-lycopene complex. The results of the FTIR spectrophotometer test showed that using acetone as the solvent produced wavenumbers similar to lycopene compared to ethyl acetate. UV-Vis spectrophotometer test results show the maximum wavelengths of the lycopene extract using acetone as the solvent were 447 nm, and 294 nm when ethyl acetate was used as the solvent. The Eg results revealed that the Eg values for the acetone and ethyl acetate extracts were 4.52 eV and 2.68 eV. Based on the results of property analysis of the two solvents used, acetone was more suitable than ethyl acetate for the extraction of tomato lycopene used as a DSSC sensitizer.
