Researchers at Arizona State University have developed a new dual-scale texturing process that can provide both a high level of light trapping and anti-reflection coating effects. First, a silica bead is deposited on the surface of the cell. Then the process uses a simple, low cost reactive ion etching system. The process works well with thin silicon cells as little cell material is removed. The cells light trapping and anti-reflective effect is improved over methods currently used in production of solar cells. Overall solar cell efficiency is improved, and at the same time thinner cells reduce the amount of silicon used in manufacturing cells, thus saving money.
- Silicon solar cells
Benefits and Advantages
- Lower Costs – Simple process that is easy to use in a manufacturing settings
- More Power – Better light-trapping improves cell efficiency
- Retrofit – Can be implemented in existing manufacturing processes
