Problems solved by technology

For micro-electrical equipment, at present, most of them are limited to micro-power consumption such as calculators, and can only supply power when there is light, and cannot supply power when there is no light. At the same time, its output is also directly subject to the intensity of light. Weak, very low actual use value
However, if it is used for a charging device with a slightly higher voltage and higher power, the problem of portability cannot be solved.

Embodiment Construction

[0014] The present invention is made up of five parts such as photoelectric board 1, capacitor 2, voltage stabilizer 3, electric quantity indicator 4, casing 7.

[0015] Commonly used photoelectric conversion elements are generally monocrystalline silicon wafers, polycrystalline silicon solar cells or gallium arsenide wafers, etc., and are used in large sizes, such as ground solar power plants, spacecraft solar panels, roof solar panels, and so on. From figure 2 , 3 It can be seen that the photovoltaic panel 1 of the present invention is a compact portable photoelectric conversion device, adopts polycrystalline silicon solar cells as photoelectric conversion elements, cuts into narrow strips with a width of only 3 to 20 mm, and connects conductive strips 9 in series to form components. Hot pressed. The polycrystalline silicon solar cells 1-1 have an inter-strip spacing of 0.5-1.2 millimeters, are insulated from each other, and can generate 0.5-10 watts of electric power und...

Abstract

A portable photoelectric power source is consisted of a photoelectric board, an electric condenser and a stabilizer, wherein the photoelectric board is composed of a plurality of thin-striped polycrystalline solar cell sheets through series connection, and the electric energy transformed by the photoelectric board is stored with the electric condenser. the electric condenser is composed of a plurality of rechargeable batteries through series connection, and the stabilizer is used for stabilizing the output voltage. The present invention can store the electric energy generated by any irradiation such as sunlight and light, as well as can be used with recharging and discharging repeatedly.

Description

technical field [0001] The invention relates to a power supply using solar energy, and belongs to the technical field of power supplies. Background technique [0002] With the development of electronic technology, many portable electronic equipment and devices such as mobile phones have appeared, which bring great convenience to people's work and life. However, these equipment and devices often need to be charged during work, and the user must carry out the work in a place with a fixed power supply, causing the use time and place of use of the above-mentioned equipment and devices to be limited to a certain extent. In order to solve the outdoor power consumption and energy-saving problems of electrical equipment, people turn their attention to solar chargers. Although solar energy has been used to generate electricity, most of it is only involved in large-scale converters, such as for solar power plants. For micro-electrical equipment, at present, most of them are limited ...
