| * Optimal distance to light source is 1,05m | * 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 | ||
