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 247mA, and Voc = 657mV. 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.

网格蛋白对染料敏化太阳能电池（DSSC-）基天然染料的性能改进

染料敏化太阳能电池 (DSSC) 是一种利用电化学原理工作的太阳能电池装置，其中敏感染料被 TiO2 光电极层吸收。基于 DSSC 的天然染料的问题是效率低于硅太阳能电池。这种低效率是由于 TiO2 半导体层中的电子转移障碍。在这项研究中，将网格蛋白添加到 TiO2 层用于增加半导体层中的电子转移，从而提高 DSSC 性能。网格蛋白是一种在真核细胞中形成转运囊泡膜的蛋白质。本研究采用的方法是在 DSSC 结构的 TiO2 中加入浓度为 0%、25%、50% 和 75% 的网格蛋白。使用数据记录器测量 DSSC 的光伏特性以确定 DSSC 的性能，使用扫描电子显微镜 (SEM) 分析层形貌，使用能量色散 X 射线光谱 (EDS) 分析 DSSC 中的元素含量，并使用功能使用傅立叶变换红外光谱 (FTIR) 分析 DSSC 层中的组。本研究的结果是添加网格蛋白可以提高 DSSC 的性能，这导致 DSSC 在添加 75% 网格蛋白时的性能最高，效率 = 1 465%，Isc = 5 247mA，Voc = 657mV。从 SEM 分析的结果来看，网格蛋白分子似乎填充了 TiO2 分子中的空腔。EDS 分析显示，随着网格蛋白浓度的增加，TiO2 层中碳、氧和磷的含量增加。
