Recent developments in dye sensitized solar cells (DSCs) have led to record-breaking cell efficiencies and speculation as to when, if ever, this technology will be commercially available. Generally, for residential solar or commerical solar installations, you have a choice between two solar technologies. These are crystalline solar panels, the solid black/blue panels on people's roofs, and thin film panels, the foldable and rollable panels that are not mounted. DSCs are a third kind of solar cell that was inspired by photosynthesis, the process through which trees harness solar energy. Amazingly these cells can be sprayed or painted onto any surface and can produce electricity from diffused light, which means orientation isn't as big a concern! If we could make cheap and efficient DSCs it would revolutionize how we get solar electricity.
