Abstract
A measuring device for the property of a photovoltaic device and a measuring method using the same are provided. The measuring device includes several light sources and a feedback control module. The light color of each light source is different and includes several light-emitting elements symmetrically configured. The feedback control module is used for controlling illuminations of the light-emitting elements for measuring the property of a photovoltaic device.
Claims16
A measuring device configured to measure a property of a photovoltaic device, comprising:
- plural kinds of light sources each having different light color, wherein each kind of light source comprises a plurality of light-emitting components symmetrically arranged;
- a feedback controlling module configured to control illumination of light emitted by the light sources and determine whether any instability of the illumination is less than a first predetermined ratio;
- and
- a measurement unit, configured to measure the property of the photovoltaic advice under illumination if the instability of the illumination is less than the first predetermined ratio.
A method configured to measure a property of a photovoltaic device, comprising:
- providing plural kinds of light sources having different light colors, wherein each kind of light source comprises a plurality of light-emitting components symmetrically arranged;
- controlling, by a feedback controlling module, illumination of light emitted by the light sources;
- determining, by the feedback controlling module, whether any instability of the illumination is less than a first predetermined ratio;
- and
- if the instability is less than the first predetermined ratio, measuring, by a measurement unit, the property of the photovoltaic device under the illumination.
