i think the paper under title ((Electrolumenscence of thin film solar cell s and PV modules camera calibration)) by M.Topic and et,al , its help you they used three different CCD cameras for electroluminesence (EL)
Yes, it is for standard silicon solar cells, or silicon solar cells with rear passivation
There are few gadgets which are available commercially:
1. Silicon solar cell panels - which are availble of any specific wattage you need.
2Street lighting using aPV panel and battery
3. Mobile lantern which are also very common in shops and in home
4.Chargin battery of the invertoers with PV panels.
5. garden lighting which operated from6pm to 12 pm and suring the day it charges its battery
thanks but I'm not asking about types of modules but about El-cameras
I have been looking into 2 infrared cameras for hot spot analysis of thin film Si-Modules, namely an IRCAM VELOX 327k SM pro (http://www.ircam.de/produkte/kamera_anzeigen_e.php?id=98) and an Infratec ImageIR 6300 (comparable to this one: http://www.infratec.de/en/thermography/infrared-camera/imageirr-7300-series.html). They both have a thermal resolution
I am using a silicon CCD-based camera by Andor for investigating the EL of polymer thin film solar cells. It comprises a backthinned array with improved sensitivity in the NIR region and is thus very suitable for also measuring silicon EL. For a report, you may read this (on the last page also measurements on a silicon solar cell are shown): http://www.lot-oriel.com/files/downloads/andor/en/AP_Characterization_of_Polymer_Solar_Cells_and_Modules.pdf
As Arnstadt is not far away from Ilmenau (I am working at the University there), I invite you to visit our labs for testing the perfomance of this camera.
