Abstract: 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.
