摘要

A faster, cheaper way to manufacture silicon solar cells, partially funded by the US Energy Department and refined at its National Renewable Energy Laboratory, has won an R&D 100 award as one of the top technology innovations of 2013. Crystal Solar, which is now developing the technology further, is expected to grow high-quality, high-efficiency silicon wafers at 100 times the usual throughput, at half the cost of traditional methods. The company's direct gas-to-wafer process is epitaxial, which means that it grows a layer of material on top of another material with the same crystal structure. Known as Direct Monocrystalline Silicon Wafer Growth by High-Throughput Epitaxy, gaseous layers of semi-conducting silicon material are grown directly on reusable silicon substrates. The method has several advantages, including eliminating the waste incurred in the traditional approach, which involves sawing thin slices from a large ingot or block of silicon. With this technique, wafers can be made thinner than by slicing, without compromising their quality or efficiency.
