Sunlight simulator provided with detection device and solar battery detection device

Abstract

The invention discloses a sunlight simulator provided with a detection device and a solar battery detection device. A body is a closed space provided with a light-emitting opening; a light emitter is arranged in the closed space and is used for emitting a first light beam towards the light-emitting opening; a light-dividing device is arranged on a traveling direction path of the first light beam and is used for dividing the first light beam into a first sub-light beam and a second sub-light beam, wherein the first sub-light beam is emitted to a solar battery to be measured at the position of the light-emitting opening and is used as solar battery detection device; moreover, the detection device is arranged on the traveling path of the second sub-light beam and is used for receiving the second sub-light beam, and the detection device outputs a signal to monitor the intensity of the first light beam emitted by the light emitter so as to ensure the measurement accuracy of the solar battery.

Description

technical field [0001] The present invention relates to a solar simulator and a solar cell detection device with a detection device, especially a detection device is arranged inside a solar simulator or a solar cell detection device for monitoring the beam intensity of an internal luminous body . Background technique [0002] At present, the solar power generation system is made of solar cells (solar cells) using the semiconductor manufacturing process. The principle of power generation is to irradiate the sun's sunlight on the solar cells, so that the solar cells absorb the sun's sunlight and pass through the semiconductors, so that negative electrodes and positive electrodes are produced. The current is formed and then transmitted to the load through the wire. [0003] Therefore, after the solar cell is manufactured through the manufacturing process, the performance evaluation of the solar cell's power generation capacity must be carried out first. If the solar cell has g...

[0006] However, the above beam intensity measurement method must project the beam onto the solar cell to be tested and the monitor cell at the same time. This operation method will require at least two light outlets for the solar simulator, or A larger light outlet will make it necessary to use a high-power luminous body inside the solar simulator, so that the solar cell and the monitoring sheet to be tested can be uniformly illuminated, and the output characteristics of the solar cell will be affected. The price of this type of high-power illuminant will be proportional to the irradiable brightness and area, so the manufacturing cost will be higher.
