VS - 9310 Solar Cell: Solar Cell Life Time Test System

Outline

A Completed Solar Cell life time test system consists of:

• Multi-Channel Programmable Power Source
   

• Solar Simulator, and Photodiode Sensor
   

• Computer with Data Acquisition Software
   

• Test Device Holder & Jig

Functions

• Programmable Power Supply with 24 channel output
  
  PV Cell Conversion efficiency: ŋ, and Fill factory: FF are calculated and being monitored.
   

• Solar Simulator
   

• Light Density Sensor ( Si-Photodiode)
  
  A Si photodiode with its sensitivity close to spectral Luminous efficiency V(λ) can be used as light density sensor, to monitor the light density changes due to the lifetime of Xenon Lamp.
   

• Test Jig
  
  To achieve an accurate measurement of Voltage, and current, the effect of contact resistance and wires' resistance must be minimized.
  
  A customized design jig with the Spring and gold plating contact probe makes the electric contact reliable, durable.
  
  To keep the test device with temperature of 25ºC, some special cares must be token:
  
  -Cooled isothermal hold down block assembly together with PV Cell
  
  -Temperature sensor placed near the PV cell;
  
  -Monitoring the Temperature real time;
