| 摘要 |
<p>The invention provides a differential voltage cell, such as a solar cell, in which both the photo-voltaic and Peltier effects are combined. The cell includes a series of interconnected cell units each comprising two spaced bodies 32, 33 including p-type and n-type semiconductor material respectively, a lens 30, an upper transparent electrical conductor 31 bridging said semiconductor bodies, and a lower electrical conductor 34 connected to each of said bodies at a location spaced from the upper conductor, the arrangement being such that the upper and lower conductors never bridge the same pair of semiconductor bodies. In another arrangement, the semiconductor bodies comprise PNP heterostructures (Fig 9, not shown). <IMAGE></p> |
