Abstract

The invention relates to the solar photovoltaic device detection technique, in particular to an LED solar simulator which can simulate the AM 1.5 standard solar spectrum and can be used for testing the generating efficiency of a solar battery or a small-sized photovoltaic component at a temperature of 25 DEG C and in the irradiation of the AM1.5 standard sun. The LED solar simulator adopts LEDs with various colors, ensures that the total combined spectrum has a range covering the solar spectrum from the near infrared to the near ultraviolet, the light intensity of various wave bands of the solar spectrum is adjusted by adjusting the number of the LEDs and the current intensity of the LEDs to realize the whole simulation of the solar spectrum. The total number of the LEDs is adjusted to satisfy the requirement of the solar simulation of a laboratory in order to realize the synthesis of the AM1.5 standard sunshine the optical radiation intensity of which is 1000W/m<2>.

Description

technical field [0001] The invention relates to the detection technology of solar photovoltaic devices, specifically a LED that can simulate the AM1.5 standard solar spectrum and can be used to test the power generation efficiency of solar cells or small photovoltaic modules under the irradiation of the AM1.5 standard sun at 25°C Solar Simulator. Background technique [0002] Solar cell photovoltaic power generation technology has been widely used now, especially small photovoltaic modules are closely related to people's life and applied to various fields. However, there is no suitable power generation efficiency testing instrument for the measurement and testing of small photovoltaic modules. This has led to the fact that each manufacturer has its own testing instruments and each has its own measurement method. The accuracy of the instrument is very poor and the error is large. . Under such circumstances, it is very necessary for us to develop a solar simulator that can a...
