Currently, the development of sensitized solar cells (DSSCs) with high power conversion efficiency and low cost is a major challenge in the academic and industrial fields. In order to enhance the current efficiency of dye-sensitized solar cells (DSSCs), a perovskite graphene-La2CuNiO6-ZnSe (G-LCN-ZS) as a counter electrode (CE) was introduced in this study via a conventional microwave treatment. A DSSC with 15% G-LCN-ZS CE achieved a high-power conversion efficiency up to 11.05% under AM 1.5G solar simulation, which is one of the highest reported efficiencies for ternary oxide-based graphene DSSCs. The G-LCN-ZS CE nanocomposites exhibit excellent catalytic activity towards the I3-/I- redox couple due to the positive synergistic effect between LCN-ZS nanoparticles and graphene sheets. Moreover, the graphene-based materials can provide a fast diffusion pathway for the electrolyte. In this paper, we have shown that alternative materials with high energy conversion efficiency can be used in future applications.
目前，开发具有高功率转换效率和低成本的敏化太阳能电池（DSSC）是学术和工业领域的一项重大挑战。为了提高染料敏化太阳能电池（DSSC）的电流效率，本研究通过传统微波处理引入了一种钙钛矿石墨烯-La2CuNiO6-ZnSe（G-LCN-ZS）作为对电极（CE）。在AM 1.5G太阳能模拟条件下，含有15% G-LCN-ZS对电极的DSSC实现了高达11.05%的高功率转换效率，这是基于三元氧化物的石墨烯DSSC报道的最高效率之一。由于LCN-ZS纳米颗粒与石墨烯片之间的正协同效应，G-LCN-ZS对电极纳米复合材料对I3-/I-氧化还原对表现出优异的催化活性。此外，基于石墨烯的材料可以为电解质提供快速扩散途径。在本文中，我们已经表明，具有高能量转换效率的替代材料可用于未来的应用。
