Description

Inclination angle testing and adjusting device for p-type back junction contact solar cell

Technical Field

The utility model relates to the field of solar cells, in particular to a testing inclination angle regulating device for a p-type back junction contact solar cell.

Background

A solar cell is a device that is responsive to light and can convert light energy into electricity. There are a number of materials that can produce the photovoltaic effect, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium diselenide, and the like. The power generation principle is basically the same, and the photo-electric generation process is now described by taking crystalline silicon as an example. P-type crystalline silicon is doped with phosphorus to obtain N-type silicon, and a P-N junction is formed.

When the light irradiates the surface of the solar cell, a part of photons are absorbed by the silicon material; the energy of photon is transferred to silicon atom, so that electron is transferred, and becomes free electron, and the free electron is concentrated on two sides of P-N junction to form potential difference, when the external circuit is connected, under the action of said voltage, the current can flow through external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electrical energy

In the selection of the inclination angle of the solar cell, the optimal angle of the solar cell panel is to obtain the most direct and vertical light rays of the solar cell panel. If your solar panels were perpendicular to the ground, they would have a 90 degree tilt. In order to collect solar energy more efficiently, the solar panel should be angled as far as possible towards the sun. Photovoltaic energy is produced when the angle of illumination of the panel surface by sunlight ("angle of incidence") is small, or when light is directed at the panel as close to normal as possible.

The most desirable tilt angle is one where the annual energy production of the solar cell is as large as possible and the difference between the winter and summer energy production is as small as possible. The local latitude or the local latitude plus a few degrees is generally taken as the tilt angle for the installation of the local solar module.

At present, the battery piece can only be arranged towards the same direction in the arrangement, so that sunlight irradiation is absorbed, the inclination angle is set according to the sunlight angle in the same direction, but the solar energy is in different directions every day, the battery piece can not move to absorb the sunlight irradiation, and the solar light can not be collected efficiently. The application aims at simultaneously adjusting the moving angle and the inclination angle of the solar cell, adjusting the facing direction of the solar cell in real time according to different directions of the sun, adjusting the inclination direction of the solar cell according to different latitudes of the sun, efficiently collecting solar illumination and improving the light energy conversion efficiency.
