New Solar Cell Manufacturing Process Makes for Low-Cost, Printable Solar Power

As our culture makes the shift away from carbon-intensive energy sources, alternative sources like solar energy from photovoltaic cells are becoming an attractive option. However, while the cost of producing solar cells has been decreasing steadily in recent years, they still require a great deal of resources to make: the silicon crystals that solar cells use not only require hazardous solvents for their production, they also need to be baked at high temperatures -- 1,000ºC (1,832ºF) -- to attain the purity required for their use, an energy-intensive process that can increase the final product's carbon footprint.
