Abstract

The present invention relates to the field of solar energy photovoltaic power generation, in particular discloses a solar energy light gathering photovoltaic power generation system. The system comprises a gathered-light receiving device (1), a light transmission pipe (2), a photovoltaic battery, a spectroscope (3) and a black box (4). The photovoltaic battery is arranged in the black box (4). The light selectively enters the black box (4) through the gathered-light receiving device (1), the light transmission pipe (2) and the spectroscope (3) and irradiates the photovoltaic battery with corresponding forbidden band width to generate power. The photovoltaic power generation system of the invention has higher light gathering radio and can save a considerable area of the photovoltaic battery. The light selectively irradiates the photovoltaic batteries with different forbidden band widths when the light is split through the spectroscope. The usage factor of light, the power generating efficiency and power output of the photovoltaic battery are increased.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a solar concentrated photovoltaic power generation system. Background technique [0002] The maximum amount of solar energy that can be received per square meter of the earth’s surface is only about one kilowatt per day. If the efficiency of photovoltaic cells is calculated at 15%, to build a 1MW power station and use flat-panel photovoltaic power generation devices, the area of ​​photovoltaic cells alone requires 10,000 square meters meters or so. Since the main cost of the photovoltaic power generation device is the photovoltaic cell, saving the area of ​​the photovoltaic cell can reduce the cost of the device, which is why the concentrated photovoltaic power generation device came into being. Although the Fresnel lens concentration ratio can be made very high, it has higher requirements on photovoltaic cell materials, processes, cooling, etc., thus limiting ...
