Abstract
The invention relates to a solar simulator and a solar simulator uniformity control method. The solar simulator comprises a pulsed solar simulator body and a uniformity component; the pulsed solar simulator body comprises a light box, and a luminous source component, a glass table-board and filter glass, which are arranged in the light box; the filter glass is located between the luminous source component and the glass table-board; the light emitted by the luminous source component passes through the filter glass and is irradiated on the glass table-board; the uniformity component is arrangedon one side of the filter glass close to the luminous source component for performing uniformity processing on the light transmitted by the luminous source component so that the irradiation unevennessof the light passing through the filter glass is smaller than or equal to preset irradiation unevenness. According to the technical scheme, the uniformity component is added on the filter glass of the original pulsed solar simulator body; the uniformity component enables the light sent out by the luminous source component is subjected to uniformity processing, thereby improving the uniformity ofthe solar simulator; therefore, the measurement precision can be improved when the solar simulator is adopted to measure a photovoltaic test battery.
Description
technical field [0001] The invention relates to the technical field of solar simulators, in particular to a solar simulator and a method for controlling uniformity of the solar simulator. Background technique [0002] At present, the photovoltaic industry usually uses solar simulators to measure the conversion efficiency or power of solar cells or solar modules. Solar simulators are divided into steady-state solar simulators and pulsed solar simulators. In order to measure the optical performance of solar simulators, the The optical indicators of solar simulators are divided into three categories, namely spectral matching, uniformity and photostability. And these three types of indicators are clearly defined in three grades (A, B, C) in the performance requirements of the IEC60904-9 solar simulator. With the development trend of the industry, the requirements for power measurement accuracy are constantly being improved, and the performance requirements of solar simulators a...
