WaveLabs Solar simulator
Some notes to not forget them.
- Optimal distance to light source is 1,05m
- Chuck (black mesuring device) is to bealigned centered, pro tip: mark the position
- Software to control chuck temperature (not yet installed) from Oven Industrial COntrols
- Turn on vaccum by turnign all three levers
- copper plate can be cleaned from oxidization by steel wool
- fill factor is the area under the MPP in realtion to the maximum possible defined by Isc and Voc. 80-82% is good. Bad FF can be because of bad contacts.
- Light intensity changes Isc.
- Temperature influences Voc (2 mV/K)
- Gap filler could be used for glass covered solar cells (mini module)
- Two profiles as templates (Std. cell & Mini Module)
- AM0 is the outer space spectrum
- SunsVOC Intesity sweep, how good could the cell be?
- cameras are from Basler
- contact pins from company Ingun
Abbreviations:
- Isc - short circuit current
- Voc - open circuit voltage (woltage without current)
- MPP - maximum power point (a small blue cross in the graph)
- ETA - efficiency
- FF - Fill factor
Ideas for “physics” experiment:
- Heating with hot air gun
- IR to test quantum efficiency?
- dark measurement, Idealitätsfaktor, 2-Dioden-Modell
