Solar car power supply

Abstract

The invention discloses a solar car power supply, and belongs to the technical field of solar cells. The solar car power supply comprises a solar cell array and a peripheral circuit; the solar cell array is paved along the outer side of the car body, and is composed of one or more GaAs-based solar cell units connected in series or in parallel, wherein each solar cell unit comprises a component layer, a metal electrode layer arranged on the component layer and a backing layer which is arranged under the component layer and compose of a metal later and a heat-conducting backing layer; the peripheral circuit is electrically connected to the solar cell array, and comprises a control circuit. The solar cell provided by the invention is efficiency and flexible, solves the problems that the existing solar car power supply is low in photoelectric converting efficiency, poor low light performance, poor wide-angle lighting, poor heat dissipation performance, insufficient flexibility and heavy weight, and can be perfectly integrated on the surface of the car; in addition, heat dissipation is good in strong sunlight in summer so as to avoid excess temperature in the car. The solar car power supply is also applicable to city busses, busses, tops of buildings and curtains facing the sun.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar car power supply with high efficiency, flexibility and good directional heat dissipation. Background technique [0002] According to the latest data released by the Traffic Management Bureau of the Ministry of Public Security, as of the end of 2013, the number of civilian cars in the country has reached 137 million, and there are 31 cities in the country with more than 1 million cars. Among them, the number of cars in Beijing, Shanghai and Tianjin is 5.30, 2.4749 and 2.589 million respectively. The sharp increase in automobiles not only consumes a lot of non-renewable petroleum resources, but also emits a large amount of pollutants such as hydrocarbons, nitrogen oxides, carbon monoxide, sulfur dioxide, lead-containing compounds, benzopyrene and solid particles, which is one of the sources of PM 2.5 pollution. Therefore Many transportation manufacturers have a strong ...
