Solar Cell Robots
New Robots Build Prototype Solar Cells in 30 Minutes, Then Evaluate Their Own Work
One multitasking robot can build semiconductors for solar cells on six-inch-square plates of glass, plastic or flexible metals in just over half an hour. Six of these tireless mechanical workers, chugging away at the National Renewable Energy Laboratory (NREL) in Colorado.
Each robot acts as a central hub or master chef that pivots around to dish out plates to different chambers. In the chambers, semiconductors are built up layer by micro-thin layer, or crystals which help make the solar cells are grown and tested.
