Among Renewable energy resources, solar power generation plays an important role and is paid more attention by modern researchers. Nowadays, extensive research is being carried to increase the efficiencies and stability of thin-film solar cells. Among thin-film solar cells, organic solar cells also known as plastic solar cells are relatively cheaper. They can be made in different colors and are very light in weight. These solar cells can be included in infrastructure such as windows, walls, car windshields, etc. Carbon nanotubes (CNTs) have some extraordinary properties such as high conductivity, high mechanical strength, and high aspect ratio along with the best physical and chemical properties. In this research, multi-walled carbon nanotubes (MWCNTs) with different concentration (1 to 5%) have been incorporated in the active layer of organic solar cells (OSCs), and improvement in short circuit current is reported. CNTs come along with entanglement and poor solubility. Ultra-sonication technique is used for dispersion and covalent functionalization technique is applied to increase the solubility of nonotubes.

将碳纳米管掺入有机太阳能电池的光敏层中

在可再生能源中,太阳能发电起着重要作用,并且受到现代研究者的更多关注。如今,正在进行大量研究以提高薄膜太阳能电池的效率和稳定性。在薄膜太阳能电池中,有机太阳能电池(也称为塑料太阳能电池)相对便宜。它们可以制成不同的颜色,并且重量很轻。这些太阳能电池可以包含在窗户,墙壁,汽车挡风玻璃等基础设施中。碳纳米管(CNT)具有一些非凡的特性,例如高电导率,高机械强度和高长宽比以及最佳的物理和化学特性。在这项研究中 在有机太阳能电池(OSC)的活性层中已掺入了不同浓度(1%至5%)的多壁碳纳米管(MWCNT),并且据报道短路电流得到了改善。碳纳米管伴随纠缠和不良的溶解性。超声技术用于分散,共价官能化技术用于增加非管的溶解度。
