Components

sun simulator : Simulate the noon sun rays, cell under test, through the test circuit for performance index of the cell under test.

Electronic load:Even the host cell, standard cell and temperature probe. To obtain the voltage and current of the cell under test; Through a standard battery for light intensity signal; Through the temperature sensor for test environment temperature, and will provide to the four groups of data acquisition card for analysis and processing.

Control circuit:Provides man-machine interface, and the control interface, provide operation interface and parameter setting.

Technical indicators

1.open circuit voltage (Voc) :Under the light, when cell did not pick up the load voltage

2.Short circuit current (Isc) :Under the light, the battery short circuit when the output current

3.Maximum power (Pmax) :Under the light, the maximum power output cell can

4.Under the maximum power of voltage (Vopt)/current (Iopt)

5.Fill factor:Pmax/Voc * Isc, reflect power output along with the changes in the load characteristics of the battery

6.Efficiency:Under the light, the working efficiency of the cell

7.The equivalent series resistance:Solar cell within the equivalent series resistance, can affect the positive volt ampere characteristics and the short-circuit current, and the increase of series resistance will make solar cells DianZhuan fill factor and light
