| 摘要 |
The invention discloses a non-imaging reflecting surface optimized for concentrating solar energy onto a high efficiency solar cell. It provides for accurate mapping of solar radiation from the reflector to the cell. Additionally it provides for using only that portion of the surface that participates in the radiation transfer and it creates substantially uniform radiation intensity on the cell surface. The uniformity applies to both the spectral and the intensity distribution of the radiation on the cell. The reflecting surface is an off-axis parabolic surface trimmed to include only ray intercepts that travel to the solar cell surface. The solar cell is located off-focus so that rays from the reflector intercept the cell surface according to a predetermined mapping.
