- Stacking Cells Could Make Solar as Cheap as Natural Gas
A novel manufacturing method could make it practical to stack solar cells and convert more of the energy in sunlight into electricity.
When experts talk about future solar cells, they usually bring up exotic materials and physical phenomena. In the short term, however, a much simpler approach—stacking different semiconducting materials that collect different frequencies of light—could provide nearly as much of an increase in efficiency as any radical new design. And a new manufacturing technique could soon make this approach practical.
