The rapid proliferation of internet-connected devices has transformed our daily habits prompting a shift towards greater sustainability in renewable energy for indoor applications. Among the various technologies available for obtaining energy in indoor conditions, Dye-Sensitized Solar Cells (DSSCs) stand out as the most promising due to their ability to efficiently convert ambient light into usable electricity. This study explores how the optimal matching of the UV-Vis absorption spectra of dyes commonly used in DSSCs with the emission profiles of indoor lamps allows for the enhanced efficiency of DSSC under indoor lighting. By testing four organic dyes with different UV-Vis absorption spectra (L1, Y123, S1, and TP1) under two different common indoor light sources (OSRAM 930 and OSRAM 765 lamp), a significant dye-lamp correlation was demonstrated. Notably, low-priced dyes like S1 and TP1, characterized by easier synthetic routes and with an optimal overlap with the dye-lamp spectrum, exhibited competitive efficiencies, narrowing the performance gap with high-performing dyes like Y123, which require more demanding preparation approaches. The study highlights the critical importance of tailoring dye selection to specific indoor lighting environments, addressing a significant gap and paving the way for more sustainable and cost-effective energy solutions for indoor applications.
联网设备的迅速普及改变了我们的日常习惯，促使室内应用在可再生能源方面朝着更高的可持续性转变。在室内条件下获取能源的各种可用技术中，染料敏化太阳能电池（DSSC）因其能够有效地将环境光转化为可用电力而脱颖而出，成为最具前景的技术。本研究探讨了DSSC中常用染料的紫外-可见吸收光谱与室内灯具发射光谱的最佳匹配如何提高室内照明下DSSC的效率。通过在两种不同的常见室内光源（欧司朗930和欧司朗765灯）下测试四种具有不同紫外-可见吸收光谱的有机染料（L1、Y123、S1和TP1），证明了染料与灯具之间存在显著的相关性。值得注意的是，像S1和TP1这样价格低廉的染料，其合成路线更简单，并且与染料-灯具光谱具有最佳重叠，表现出具有竞争力的效率，缩小了与需要更苛刻制备方法的高性能染料（如Y123）之间的性能差距。该研究强调了根据特定室内照明环境选择合适染料的至关重要性，填补了一个重大空白，并为室内应用中更可持续、更具成本效益的能源解决方案铺平了道路。
