DYSCRETE – SOLAR POWER FROM CONCRETE
DysCrete is an innovative approach to the generation of energy, based on the same underlying principles as dye-sensitized solar cells (DYSC), from which it gains its name. Like other cells based on DYSC technology, DysCrete uses organic dyes to absorb light and produce electricity through electrochemical reactions. Analysis of this still novel process reveals a high degree of compatibility between DYSC technology and the chemistry and physics of concrete, including its material logic and production methods. DYSC cells are modeled on nature. Much like chlorophyll-bearing plants, they absorb light not with semiconductor materials, but with organic dyes held in suspension. In this sense, the technology is an adaptation of the photosynthetic process.
THE DYSCRETE CONCEPT
HOW THE PROCESS WORKS
Technically, the DysCrete cell is based on a simple structure of functional layers. These combine to form a redox reaction coating that generates energy through an electrochemical process when exposed to light. This coating can be created on concrete surfaces by systematically modifying their physical and chemical structure while applying and integrating specific substances. The electricity-generating material is refined through a process of synthesis and layering, a combination of sintering and spray deposition that can easily be integrated into the production of prefabricated elements. By adjusting the dye and electrolyte components, the layer system can be tuned to specific wavebands of light, including the very edges of the visible spectrum. One major advantage of dye-sensitized concrete is its relatively low production cost, giving the system great potential as a low-cost energy source.
ENERGY-GENERATING CONCRETE
DysCrete combines the advantages of technological photosynthesis and concrete. The basis of the system is concrete, with its many positive qualities as a structural product (fire resistance, high strength and durability, variety of construction methods). The energy-generating function is produced with freely available components, with no additional toxic emissions. The innovative system of materials is renewable, largely recyclable and environmentally friendly. Because it can make use of the energy in diffuse light, its structural applications are virtually unlimited compared to conventional photovoltaic systems, opening up a world of possibilities in the field of structurally integrated photovoltaics. DysCrete is ideally suited for manufacturing prefabricated concrete elements for building construction, for new types of building facades, and for indoor and outdoor wall and floor systems.
