Initial solar cell characterisation test and comparison with a LED-based solar simulator with variable flash speed and spectrum

A continues-wavelength LED-based solar simulator has been developed to optimise the measurement of solar cells. It achieves more then one Sun intensity over an area of 200x200mm2. Use of LEDs as the main light source enabled advanced functions like variable flash speed and shape and variable spectrum. The simulator hardware is described briefly and simulator classification results are given. Initial measurements with error analysis of a mono crystalline silicon solar cell are presented, proofing that a LED-based solar simulator has potential to outperform today’s state of the art solar simulators.
