Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.

Using light to produce either electricity or hydrogen, dye-sensitised solar cells (DSSCs) are currently the most efficient third-generation solar technology. Increases in their conversion efficiency through better understanding of how light-absorption materials function will make them attractive for large-scale deployment.
