   * Turn on vaccum by turnign all three levers   * Turn on vaccum by turnign all three levers
   * copper plate can be cleaned from oxidization by steel wool   * 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
