TiO2 nanoparticle-based dye sensitized solar cells (DSSCs) have attracted a significant level of scientific and technological interest for their potential as economically viable photovoltaic devices. While DSSCs have multiple benefits such as material abundance, a short energy payback period, constant power output, and compatibility with flexible applications, there are still several challenges that hold back large scale commercialization. Critical factors determining the future of DSSCs involve energy conversion efficiency, long-term stability, and production cost. Continuous advancement of their long-term stability suggests that state-of-the-art DSSCs will operate for over 20 years without a significant decrease in performance. Nevertheless, key questions remain in regards to energy conversion efficiency improvements and material cost reduction. In this Perspective, the present state of the field and the ongoing efforts to address the requirements of DSSCs are summarized with views on the future of DSSCs.
基于二氧化钛纳米颗粒的染料敏化太阳能电池（DSSC）因其作为经济可行的光伏器件的潜力而引起了极大的科技关注。虽然DSSC具有多种优点，如材料丰富、能量回收期短、功率输出恒定以及与柔性应用兼容等，但仍有一些挑战阻碍其大规模商业化。决定DSSC未来的关键因素包括能量转换效率、长期稳定性和生产成本。其长期稳定性的不断提高表明，最先进的DSSC将运行20多年而性能不会显著下降。然而，在提高能量转换效率和降低材料成本方面仍存在关键问题。在这篇综述中，总结了该领域的现状以及为满足DSSC要求而正在进行的努力，并对DSSC的未来进行了展望。
