Dye Sensitized Solar Cells (DSSC) Dengan Material Aktif Nanokomposit ZnO/TiO2 Dan Material Penghambur SiO2

---

Utilization of solar energy is converted into electrical energy using conversion
devices, namely solar cells. So far the development of solar cells has undergone three
generations. The development of third generation solar cell research achieves an
efficiency of 14% for Dye Sensitized Solar Cells (DSSC). DSSC is a solar cell that has
high potential and is environmentally friendly. Photoanode modification is one way of
developing DSSC, including the development of nanocomposites and the addition of
light scattering layers. The challenge in increasing the efficiency of Dye Sensitized
Solar Cell (DSSC) is high recombination and low absorption. In this research,
ZnO/TiO2 nanocomposites were used to reduce recombination and added SiO2
scattering materials to increase light absorption. The ZnO/TiO2 nanocomposite can be
used as electron transport and is stable for electrolytes, thereby reducing
recombination and increasing current, and increasing DSSC efficiency. In addition,
the increased SiO2 light scattering at the photoanode can extend the light path,
resulting in better current density and efficiency.
This research was carried out by varying the volume ratio of the ZnO/TiO2
nanocomposite and varying the layer of SiO2 on top of the ZnO/TiO2 nanocomposite.
This study aims to examine the effect of the volume ratio of ZnO/TiO2 nanocomposite
and SiO2 coating on DSSC performance. The ZnO synthesis method used is seed
mediated hydrothermal. ZnO/TiO2 volume variations are 75%:25%, 80%:20%,
85%:15%, 90%:10%, 100%:0% and variations of SiO2 scattering material layers,
namely 1, 2, and 3.
The results of the analysis showed that the ZnO/TiO2 nanocomposite produced
better physical properties than pure ZnO. These physical properties can be seen from
the results of UV-Vis, XRD, and FESEM characterization. In addition, coating the
SiO2 scattering material on the ZnO/TiO2 nanocomposite has an adverse effect on the
physical properties. this is because if too much addition of SiO2 scattering material
causes low absorption and morphological damage. The effect of the volume ratio of
ZnO/TiO2 nanocomposites on DSSC performance can increase efficiency by 87.8%
compared to ZnO, and coating SiO2 scattering material on ZnO/TiO2 nanocomposites
can also increase efficiency by 48.40% compared to ZnO/TiO2 nanocomposites and by
178, 67% compared to ZnO. Optimum results obtained by the volume ratio of the
nanocomposite were 85%:15% and 1 layer of SiO2 on top of the ZnO/TiO2
nanocomposite.
