| 摘要 |
The invention consists of a thermophotovoltaic system of concentrating type photovoltaic cells, which presents the following improvements : a) the efficiency of the crystalline photovoltaic cells can be more than doubled by the transformation of the solar radiation spectrum into a narrow band infrared spectrum (852 to 894 nm wavelength) representing the maximum sensitivity of the cells; b) stabilisation and control of the temperature of the emissive tungsten mantle resulting in maximization of the system efficiency; c) possibility of direct current production with the maximum sensitivity of the photovoltaic cells; d) possibility of alternating current production, with the photovoltaic cells appropriately wired, by rotation of the tungsten mantle with or without cooperation of the control grids; e) possibility of direct conversion of the thermal radiation produced by the combustion of conventional fuels, such as H and O, by the transformation of the thermal energy into a narrow band infrared radiation, and its conversion into direct or alternating current by the thermophotovoltaic system. |
