- Dye-Sensitized Solar Concrete is a transdisciplinary, transnational research project dedicated to the development of a novel photoactive building material for use in architecture, infrastructure, and design. Based on the technology of a dye-sensitized solar cell (O’Regan and Gratzel 1991), this material uses organic dyes on concrete to absorb light and produce electricity through electrochemical reactions. One great advantage of this type of cell is its ability to utilize diffuse light. As a result, its potential applications are almost unlimited with regard to shape, design, and location. The ultimate goal is to develop a fully structurally integrated photovoltaic material.
