Solar cells, which convert sunlight to electricity, have long been part of the global vision for renewable energy. Although individual cells are very small, when upscaled to modules, they can be used to charge batteries and power lights. If laid side-by-side, they could, one day, be the primary energy source for buildings. But the solar cells currently on the market utilize silicon, which makes them expensive to fabricate when compared to more traditional power sources.
