Description

A kind of solar cell

Technical field

The utility model relates to a kind of battery, particularly a kind of battery that utilizes solar energy.

Background technology

Existing dry cell is owing to use more convenient, be widely used in daily lifes such as flashlight, broadcast receiver with on the compact electric apparatus, but this class dry cell exists following problem: 1. adopt dry cell power supply, voltage descends after use a period of time, need to change battery, cause spending to increase; 2. dry cell, needs to concentrate and reclaims, otherwise pollute the environment so can not arbitrarily abandon owing to contain harmful substances such as mercury, cadmium, free chloro ion.

Contain non-ferrous metals such as a large amount of zinc, manganese, copper in the scrap dry battery, only 2,007 one, China just consumed 15,600,000,000 the joint, more than 30 ten thousand tons of scrap dry batteries, contained metallic zinc just is equivalent to the annual production in 2 medium-sized mines, but wherein only have 2% obtain recycling.

Solar energy is pollution-free, do not have transportation, do not have monopolization, " inexhaustible, nexhaustible ", is the most rising regenerative resource.In order to reduce greenhouse gas emission and to satisfy the growing electricity needs of China, China promotes regenerative resource development, particularly solar energy and wind energy energetically.

Solar power system is made up of solar battery group, controller, storage battery (group).As out-put supply is alternating current 220V or 110V, also needs to dispose inverter.

Solar panel is to be the device of electric energy with the luminous energy effective conversion.Solar panel constitutes by a plurality of unit are compound, and the photoelectricity that each unit by using semiconductor P-N utmost point produces becomes electric energy with transform light energy.

The photoelectric conversion efficiency of monocrystaline silicon solar cell is about 15% at present, the highest reaches 24%, be that photoelectric conversion efficiency is the highest in the solar cell of present all kinds, technology is maturation but cost of manufacture is very big the most also, so that it can't be by extensively a large amount of and use at large.

The researcher of U.S. Rensselaer Polytech Inst developed a kind of new coating in 2008, it is covered can make the latter's sunlight absorption rate bring up to 96.2% on the solar panel, and the sunlight absorption rate of conventional solar cells plate only was about 70%.

At present, along with the development of solar utilization technique, the solar cell of cleanliness without any pollution is utilized more and more widely by all trades and professions.The solar energy optical-thermal industry makes the new forms of energy strategy have more realistic meaning in the high popularity rate and the high potentiality that substitute of China.

The utility model content

Technical problem to be solved in the utility model is to overcome the defective of above-mentioned prior art, and a kind of solar cell is provided, to solve the problem of existing dry cell environmental pollution.

In order to address the above problem, the technical solution of the utility model is such:

A kind of solar cell, comprise solar panel, controller, storage battery, described solar panel is connected with storage battery by controller, it is characterized in that, described solar panel, controller and storage battery are installed in the transparent outer cover, be provided with the both positive and negative polarity of solar cell at the two ends of transparent outer cover, the both positive and negative polarity of solar panel is connected with the both positive and negative polarity of storage battery by controller, and the both positive and negative polarity of storage battery is connected with the both positive and negative polarity of the solar cell at transparent outer cover two ends.

Described transparent outer cover is a cylindrical shape, and a rotating shaft is passed at the center.

Beneficial effect, solar cell of the present utility model compared with prior art because the employing photovoltaic is made power supply, thereby have reduced environmental pollution.And solar cell of the present utility model can repeated multiple times ground to charge in batteries, substitute dry cell commonly used, thereby also saved resource, application prospect is extensive.
