例句與造句

1. Amonix CPV systems use refractive Fresnel lenses to focus sunlight 500 times onto multijunction solar cells.
2. The multijunction solar cells used in Amonix CPV systems work by layering semiconductor materials that have different band gaps.
3. In 2007, the company began incorporating multijunction solar cell technology originally developed for the space industry into its modular design.
4. The Amonix CPV system is composed of seven proprietary MegaModules " !, each with 36 acrylic lenses and multijunction solar cell collector plates.
5. Used in conjunction with concentrator optics such as Fresnel lenses, multijunction solar cells are capable of converting sunlight into electricity exceeding 40 percent efficiency.
6. It's difficult to find multijunction solar cell in a sentence. 用multijunction solar cell造句挺難的
7. In this way, multijunction solar cells are more efficient than single layer solar cells because less of the photon s energy is lost to heat when it exceeds the band gap of the absorbing semiconductor material.
8. So there is a perfect frequency where multiplying energy * number of photons is maximized . ( I could not immediately find what that number is for the sun . ) There is also a Multijunction solar cell which layers the cells, each layer collects from a different frequency.
