Dye-Sensitized Solar Cell (DSSC) is a solar cell device that works using electrochemical principles in which sensitive dyes are absorbed in the TiO2 photoelectrode layer. The problem of DSSC-based natural dyes is the lower efficiency than silicon solar cells. This low efficiency is due to the barrier of electron transfer in the TiO2 semiconductor layer. In this study, the addition of clathrin protein to the TiO2 layer was used to increase electron transfer in the semiconductor layer resulting in improved DSSC performance. Clathrin is a protein that plays a role in the formation of transport vesicle membrane in eukaryotic cells. The method used in this study is clathrin protein with a concentration of 0%, 25%, 50%, and 75% added to TiO2 in DSSC structure. Photovoltaic characteristics of DSSC were measured using a data logger to determine the performance of DSSC, layer morphology was analyzed using Scanning Electron Microscopy (SEM), the element content in DSSC was analyzed using Energy-Dispersive X-ray Spectroscopy (EDS), and functional groups in DSSC layers were analyzed using Fourier-Transform Infrared Spectroscopy (FTIR). The result of this study is the addition of clathrin protein can improve DSSC performance, which resulted in the highest performance of DSSC on 75% clathrin protein addition with efficiency=1.465%, Isc=5.247 mA, and Voc=657 mV. From the results of SEM analysis, it appears that clathrin protein molecules fill the cavities in TiO2 molecules. EDS analysis shows an increase in carbon, oxygen, and phosphorus content in TiO2 layers with increasing clathrin protein concentration. FTIR analysis shows an increasingly sharp absorption in the FTIR spectrum of protein-forming functional groups by increasing clathrin protein concentration in DSSC.

<p>Modification of cyanidin as sensitiser on Dye Sensitized Solar Cell (DSSC) has been carried out theoretically in this study using rhodanine acetic acid. The rhodanine acetic acid as electron withdrawing group can increase the electron density of the LUMO state, so injection of the excited electron to the semiconductor can also be increase. The theoretical method used is DFT/B3LYP theory by <em>NWChem</em> software. The calculation shows that the LUMO energy of cyanidin rhodanine acetic is higher than cyanidin, so electron injection to the conduction band of the semiconductor is easier. This condition is supported by reduced of HOMO-LUMO energy gap, so the range of the sunlight that can be involved in the electron excitation process is wider. In addition, the LUMO electron density of the cyanidin rhodanine acetic is localized at rhodanine acetic which makes the distance of the excited electron is closer to the semiconductor, thereby facilitating electron injection.</p>

In comparison with traditional solid p-n junction solar cells, the process of light-to-electric transformation in dye-sensitized solar cells is complicated. In order to obtain a comprehensive understanding of the physical and chemical mechanism in the complicated process, people have proposed some models to describe electron injection, diffusion and recombination occurred in the process. In this paper, we will give a brief review on these models. The electrical characteristic of dye-sensitized solar cell can be well described by the diffusion model, which was originally proposed by Södergren and later further developed by Ferber, Anta, Bisquert et al. The electron injection, diffusion and recombination manifest themselves via three parameters: injection efficiency η inj , diffusion coefficient D and recombination rate (time) K (τ) in the diffusion equation. Meanwhile, some microscopic models have also been developed to evaluate η inj , D and K. The dynamical behavior of electron injection can be described by a kinetic theory, and corresponding η inj can be understood from a conduction-band fluctuation model or a two-energy-level model. The power-law dependence of D and K on electron density can be well explained by trapping model, but the temperature behavior of D cannot be explained by this model. In the potential barrier model, a weak electron-density-dependent D is obtained, and the observed temperature dependence of D in experiment is naturally expected. Although currently the relevant experimental results cannot be consistently explained within one model, we believe that these models still are important for us to understand the physical and chemical mechanism in these microscopical processes and are helpful for us to further improve the photovoltaic performance of dye-sensitized solar cell.
