Solar City? Turning Buildings Into Power Plants

in urban areas, color seems to be main focus, with a veritable rainbow of photovoltaic options now commercially available. But changing the color of a solar panel is not straightforward.

Let’s start with crystalline silicon panels, which in their ‘natural’ state tend to appear blue or black. This tells us a bit about how the material is made. The dark blue, sparkly appearance of polycrystalline solar cells results from the geometric crystals that naturally form when molten silicon is allowed to cool slowly. When sunlight falls on them, a small proportion of it is reflected from these crystal edges, rather than being absorbed by them.

Monocrystalline solar panels, as their name suggests, are each made from a single silicon crystal. They absorb all of the visible light that falls on them, which is why they look black, but they’re considerably more expensive to make. In practical applications, all crystalline silicon solar panels also have an anti-reflective coating applied to them – it reflects blue light, further adding to the blue tint.

But while crystalline silicon panels work well for walls or on roofs, they are most often opaque, which renders them unsuitable for use as windows. We need a transparent option, and that’s really where thin-film solar materials come in.Dye-sensitized solar cells have been around for close to 30 years, which makes them the original colorful photovoltaics.

Though less efficient than silicon solar cells, these cells have multiple advantages. They’re cheap and relatively simple to produce, they’re partially flexible and semi-transparent, and they work under non-direct sunlight. So it’s no real surprise that DSSCs have attracted a lot of attention for use in windows, art installations and shading facades and structures.
