| 摘要 |
The invention relates to a photovoltaic device for directly converting solar power into electrical power using a solar cell which has a smaller areal expanse than a light inlet area on the photovoltaic device, an optical unit for concentrating or focusing the solar radiation entering through the light inlet area onto a prescribed region which is determined by the relatively small area of the solar cell, is at a distance from the light inlet area and has a smaller area than the light inlet area, and a transparent support on which the solar cell is fitted. For simpler and economic manufacture of the device, it is proposed that the support be a transparent light outlet body through which the concentrated or focused solar radiation can pass and that the solar cell be fitted on a side of the light outlet body which is remote from the light inlet area and/or the optical unit. In addition, a PV concentration module formed from a plurality of such photovoltaic devices and an advantageous production method therefor are proposed. |
