Organic–inorganic perovskite solar cells (PSC) are gaining widespread recognition due to their higher performances and low-cost relative to other photovoltaic technologies. However, the efficient charge collection and rapid electron transportation are the key parameters desirable for the development of optimized electron transport layer (ETL) in PSC. In this research work, hydrothermally synthesized zirconium-doped titania nanoparticles (Zr-TiO₂) were introduced as an ETL in a n–i–p planar configuration. The Zr-doped TiO₂ nanoparticles were characterized for various morphological, structural and optical studies by using SEM, EDX, XRD, Raman, PL and UV-Vis spectroscopy techniques. The photocatalytic activity of newly synthesized Zr-TiO₂ nanoparticles was investigated by CV, EIS and tafel measurements. The current–voltage characteristics (J-V) of the newly fabricated PSC devices were investigated under 1 sun condition. The superior power conversion efficiency (PCE) of 12.35 % was observed with 0.2 M Zr-doped TiO₂ based ETL in PSC. The remarkable PCE in 0.2 M Zr-doped TiO₂ nanoparticles-based PSC is attributed to significant enhancement in charge carrier extraction and due to less recombination reactions at interfaces.

有机-无机钙钛矿太阳能电池（PSC）由于相对于其他光伏技术具有更高的性能和低成本而获得广泛认可。然而，有效的电荷收集和快速的电子传输是开发 PSC 中优化电子传输层 (ETL) 所需的关键参数。在这项研究工作中，水热合成的掺锆二氧化钛纳米粒子（Zr-TiO ₂）被引入作为 an-i-p 平面配置的 ETL。通过使用 SEM、EDX、XRD、拉曼、PL 和 UV-Vis 光谱技术对 Zr 掺杂的 TiO ₂纳米粒子进行了各种形态、结构和光学研究。新合成的Zr-TiO ₂的光催化活性通过 CV、EIS 和 tafel 测量研究了纳米颗粒。在 1 个阳光条件下研究了新制造的 PSC 器件的电流 - 电压特性（JV）。在 PSC 中使用基于0.2 M Zr 掺杂的 TiO ₂的 ETL观察到 12.35% 的优异功率转换效率 (PCE) 。基于 0.2 M Zr 掺杂的 TiO ₂纳米粒子的 PSC 中显着的 PCE归因于电荷载流子提取的显着增强以及界面处较少的复合反应。
