“…DSSCs with toxic materials achieve a power conversion efficiency (PCE) of above 14% while using metal-based dyes, such as ruthenium and platinum counter electrodes [45][46][47]. DSSCs made from non-toxic material, as produced in our laboratory, based on natural, plant-based dyes with graphite counter electrodes reach efficiencies below 1% [48][49][50].…”

In a world with growing demand for resources and a worsening climate crisis, it is imperative to research and put into practice more sustainable and regenerative products and processes. Especially in the energy sector, more sustainable systems that are recyclable, repairable and remanufacturable are needed. One promising technology is dye-sensitized solar cells (DSSCs). They can be manufactured with low energy input and can be made from non-toxic components. More than 70% of the environmental impact of a product is already determined in the design phase of a product, which is why it is essential to implement repair, remanufacturing and recycling concepts into the product design. In this publication, we explore appropriate design principles and business models that can be applied to DSSC technology. To realize this, we applied the concept of Circo Track, a method developed by the Technical University of Delft, to DSSCs and investigated which design concepts and business models are applicable. This method enables companies to transform a product that is disposed of after its useful life into one that can be used for longer and circulates in material cycles. The most important result is the description of a performance-based business model in which DSSCs are integrated into the customer’s building and green energy is provided as a service. During the operational phase, data is collected for product improvement and maintenance, and repair is executed when necessary. When the contract expires, it can be renewed, otherwise the modules are dismantled, reused, remanufactured or recycled.

“…Ein illustratives Beispiel für die Funktionalisierung von Nanopartikeln durch Liganden findet sich in Farbstoffsolarzellen [10, 11], bei denen TiO 2 ‐ (oder ZnO‐) Nanopartikel mit organischen/metallorganischen Farbstoffen bedeckt sind. Titandioxid ist ein n‐Halbleiter, absorbiert aber erst im nahen UV‐Bereich des Spektrums.…”

Zusammenfassung Atome auf der Oberfläche eines Festkörpers haben, da sie unterkoordiniert sind, andere Eigenschaften als jene im Inneren. Wegen des hohen Anteils an Oberflächenatomen sind deren Auswirkungen auf die Eigenschaften von Nanopartikeln nicht mehr zu vernachlässigen. Zur Erniedrigung der Oberflächenenergie können Nanopartikel mit einer schützenden Hülle an Oberflächengruppen (Liganden) umgeben werden. Diese stabilisiert nicht nur die Nanostrukturen und begrenzt ihr Wachstum, sondern hat auch großen Einfluss auf deren Elektronenstruktur sowie strukturelle und physikalische Eigenschaften. Hand in Hand mit einem besseren Verständnis der Oberflächenchemie von Nanopartikeln geht auch die Entwicklung von Methoden, die Ligandenhülle zielgerichtet aufzubauen und zu modifizieren.

“…DSSCs with the highest efficiency are using materials like ruthenium, cobalt, silver and platinum [3], which are toxic or scarce [11]. Thus, these DSSCs pose high risk to people working with the cells, the environment in which they will be used and at the end, the toxic waste must be disposed of.…”

Review of State of the Art Recycling Methods in the Context of Dye Sensitized Solar Cells

et al. 2021

In times of climate change and dwindling fossil resources, the need for sustainable renewable energy technologies gains importance, increasingly fast. However, the state of the art technologies are energy intensive in their production, like monocrystalline photovoltaic, or even consist of not recyclable composite material, in the case of wind turbine blades. Despite a lack in efficiency and stability, dye sensitized solar cells (DSSC) have a high potential to supplement the state of the art green energy technology in future. With low production costs and no necessity for toxic compounds DSSCs are a potential product, which could circulate in the loops of a circular economy. Therefore, with this paper, we provide the status of research on DSSC recycling and an outlook on how recycling streams could be realized in the future for glass-based DSSCs without toxic components. The overview includes work on using recycled material to build DSSCs and extending the life of a DSSC, e.g., through rehydration. We also illustrate the state of sustainability research for DSSCs using the VOSviewer tool. To date, the term sustainability appears in 35 of 24,441 publications on DSSCs. In view of the global challenges, sustainability should be researched more seriously because it is as important as the efficiency and stability of DSSCs.
