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
