Abstract

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.

优化DSSCs的室内照明性能：匹配有机染料吸收和室内灯具发射概况，以最大限度地提高效率。

互联网连接设备的迅速普及已经改变了我们的日常习惯，促使室内应用转向可再生能源的更大可持续性。在各种可用于在室内条件下获得能量的技术中，染料敏化太阳能电池（DSSCs）因其有效地将环境光转换为可用电能的能力而脱颖而出，成为最有前途的技术。本研究探讨了如何将DSSC中常用染料的紫外-可见吸收光谱与室内灯具的发射曲线进行最佳匹配，从而提高DSSC在室内照明下的效率。通过在两种常见的室内光源（欧司朗930和欧司朗765灯）下测试四种不同紫外可见吸收光谱的有机染料（L1、Y123、S1和TP1），证明了染料与灯的显著相关性。值得注意的是，像S1和TP1这样的低价染料，其特点是更容易合成路线，并且与染料灯光谱有最佳重叠，表现出具有竞争力的效率，缩小了与高性能染料（如Y123）的性能差距，后者需要更严格的制备方法。该研究强调了根据特定的室内照明环境定制染料选择的重要性，解决了一个重大的差距，并为室内应用的更可持续和更具成本效益的能源解决方案铺平了道路。

期刊介绍： ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
