The depletion of fossil fuel and environmental anxieties has led to a greater interest in renewable forms of energy. To a large extent, the most prevalent form of renewable energy presently is solar energy. The Dye-sensitized solar cell (DSSC) is a promising substitute for all too familiar silicon solar cells. DSSC uses dyes as light-harvesting pigments in the conversion of solar energy to electric energy. This study is about the fabrication of DSSC using a photoanode made up of TiO 2 fused with gold nanoparticles. Gold nanoparticles enhance the performance of DSSC due to the plasmonic effect. The gold nanoparticles were made by the citrate method and characterized using UV–visible spectroscopy and dynamic light scattering. The performance of the solar cells was accessed via photocurrent and photovoltage measurements. The solar-to-electric power efficiency of the solar cells with gold nanoparticles was found to be about 50% higher than those without gold nanoparticles.

等离子体金纳米粒子修饰的光敏染料敏化太阳能电池

化石燃料和环境焦虑的枯竭导致人们对可再生能源产生了更大的兴趣。在很大程度上,可再生能源目前最普遍的形式是太阳能。染料敏化太阳能电池(DSSC)是所有太熟悉的硅太阳能电池的有前途的替代品。DSSC在将太阳能转换为电能时使用染料作为集光颜料。这项研究是关于使用由TiO 2组成的光阳极制造DSSC的与金纳米粒子融合。由于等离子效应,金纳米颗粒增强了DSSC的性能。金纳米颗粒是通过柠檬酸盐方法制得的,并使用紫外可见光谱和动态光散射进行了表征。太阳能电池的性能可通过光电流和光电压测量获得。发现具有金纳米颗粒的太阳能电池的太阳能发电效率比不具有金纳米颗粒的太阳能电池的太阳能发电效率高约50%。
