In this research, treated metakaolinite (TMK) was introduced into the TiO₂ photoelectrode to fabricated dye-sensitized solar cells (DSSCs). The photovoltaic cells have four main natural components, i.e., a photosensitizer (carotenoid bixin), photoelectrode (TiO₂/kaolinite), electrolyte (glycerine carbonate derivative), and counter-electrode (carbon). Their stability, reusability, and equivalent circuit were studied. The presence of 5% of TMK in anatase TiO₂ paste decreased the TiO₂ band gap from 3.21 to 3.16 eV. The result showed that the presence of 5% of TMK in TiO₂ paste was more favorable to obtain higher energy conversion efficiency. Under a light intensity of 200 W/m², it produced an energy conversion yield of 0.086%. The combination of the electrolyte and the TMK demonstrated a synergistic effect to improve the electrical properties of the DSSC. The energy storage function worked well until the third day of analysis. The DSSC based on TiO₂/TMK photoelectrode exhibited 16 times better stability than pure TiO₂-based photoelectrode. The Faraday charge transfer processes showed that the TiO₂/TMK photoelectrode is not in direct contact with the carbon counter-electrode.

在这项研究中，将处理过的偏高岭石（TMK）引入到 TiO ₂光电极中以制造染料敏化太阳能电池（DSSC）。光伏电池具有四种主要的天然成分，即光敏剂（类胡萝卜素联素）、光电极（TiO ₂ /高岭石）、电解质（甘油碳酸酯衍生物）和反电极（碳）。研究了它们的稳定性、可重用性和等效电路。锐钛矿 TiO ₂糊中 5% TMK 的存在将 TiO ₂带隙从 3.21 eV降低到 3.16 eV。结果表明，在TiO ₂浆料中加入5%的TMK更有利于获得更高的能量转换效率。200 W/m ²光强下，它产生了 0.086% 的能量转化率。电解质和 TMK 的组合显示出协同效应以改善 DSSC 的电性能。直到分析的第三天，能量存储功能都运行良好。基于TiO ₂ /TMK 光电极的DSSC表现出比纯TiO ₂基光电极高16 倍的稳定性。法拉第电荷转移过程表明，TiO ₂ /TMK 光电极不与碳对电极直接接触。
