Abstract

The photovoltaic study of the fabricated dye sensitized solar cells is revealed in this paper. To provide indium free approach, fluorine doped tin oxide (FTO) and aluminium doped zinc oxide (AZO) glass substrate were used as charge collectors for counter electrodes and photoanode respectively. Also, a novel and natural mixed dye was used as sensitizer and mixture of doped polymer (polyaniline with metallic oxides of tin, vanadium and cerium) and iodide-triiodide couple was utilized as electrolyte for the cell. Optical band gap and light absorption performance of dyes were studied by ultraviolet–visible (UV–vis) spectroscopy. Surface morphology and elemental composition of polymer composites was studied using scanning electron microscopic (SEM) with energy dispersive X ray (EDX) analysis. Phase analysis of the composites was determined by X-ray diffraction and thermal behavior with the help of thermogravimetric analysis (TGA). Photovoltaic characteristics (I–V) and induced photon to current efficiency (IPCE) measurements were also investigated. Highest IPCE of 17.7 % was observed when polyaniline was doped with oxide of vanadium. Hence an efficient, green, indium free and novel cell is fabricated by the usage of different charge collector substrate, natural dye sensitizer and quasi solid-state electrolyte.

使用聚苯胺复合材料提高无铟染料敏化太阳能电池的性能

本文对所制造的染料敏化太阳能电池进行了光伏研究。为了提供无铟方法，掺氟氧化锡（FTO）和掺铝氧化锌（AZO）玻璃基板分别用作反电极和光阳极的电荷收集器。此外，一种新型天然混合染料被用作敏化剂，掺杂聚合物（含有锡、钒和铈金属氧化物的聚苯胺）和碘-三碘化物对的混合物被用作电池的电解质。通过紫外-可见（UV-vis）光谱研究了染料的光带隙和光吸收性能。利用扫描电子显微镜（SEM）和能量色散 X 射线（EDX）分析法研究了聚合物复合材料的表面形态和元素组成。通过 X 射线衍射和热重分析（TGA）确定了复合材料的相分析和热行为。此外，还对光伏特性（I-V）和诱导光子电流效率（IPCE）进行了测量。当聚苯胺掺杂氧化钒时，IPCE 最高，达到 17.7%。因此，通过使用不同的电荷收集基底、天然染料敏化剂和准固态电解质，制造出了一种高效、绿色、无铟的新型电池。
