#CMT# #/CMT# The detecting device (1) has radiation sources (3,5) which are formed to produce electromagnetic jets (10), particularly in the visible wavelength area. The radiation source is provided on a solar cell surface of the solar cell and emits to irradiate in an extended solar cell level. A damage detection unit (17) is operatively connected at the input side with a detector (9) and is formed to receive an image data set and to detect the mechanical damage in a semiconductor material of the solar cell, particular a scratch (32,32'), a tear (33,34,34') or a break (35,36,36'). #CMT# : #/CMT# An independent claim is included for a method for detecting a damage of a solar cell. #CMT#USE : #/CMT# Detecting device for detecting a damage of a solar cell by photoluminescence. #CMT#ADVANTAGE : #/CMT# The damage detection unit is operatively connected at the input side with a detector and is formed to receive an image data set and to detect the mechanical damage in a semiconductor material of the solar cell, particular a scratch, a tear or a break that is invisible with the naked eye, and hence ensures to reduce the failure rate of the solar cell. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a detecting device. 1 : Detecting device 2 : Solar cell 3,5 : Radiation sources 9 : Detector 17 : Damage detection unit 32,32' : Scratches 33,34,34' : Tears 35,36,36' : Breaks. |
