利用尖晶石材料推进太阳能电池发展Advancing Solar Cells With Spinels
➀ 克雷塔罗自治大学的研究团队利用无毒的(Ca,Ba)ZrS₃硫族钙钛矿与尖晶石氧化物（如NiCo₂O₄、ZnCo₂O₄）作为空穴传输层，开发出效率超过34%的太阳能电池；
➁ SrFe₂O₄尖晶石表现最优，实现34.24%的转换效率、0.11V的低能量损失和42%的光吸收率，归因于能带优化和界面缺陷控制；
➂ 该技术具备环境友好、高热稳定性及可扩展性，为新一代高效太阳能电池的商业化提供了突破性解决方案。
➀ Researchers from Autonomous University of Querétaro developed solar cells using non-toxic (Ca,Ba)ZrS₃ chalcogenide perovskite and spinel oxides (NiCo₂O₄, ZnCo₂O₄, etc.) as hole transport layers (HTLs), achieving over 34% power conversion efficiency (PCE).
➁ The SrFe₂O₄ spinel HTL demonstrated optimal performance with 34.24% PCE, low energy loss (~0.11 V), and high light absorption (~42%), attributed to improved band alignment and interface engineering.
➂ This eco-friendly, lead-free approach combines stability, scalability, and superior efficiency, positioning spinel-integrated solar cells as a promising solution for next-generation renewable energy systems.
