Recap notes from last week
Contact more people:
Follow up on already sent emails (shows interest and persistence)
E.F.-- Speedway *reach out -preliminary dates Jan. 7th (before end of break?)
Livestream race in the presentation?
Maybe link it to the website too?
Website and Emails
Assembly/ Presentation post-Christmas break…
How to solder solar cells together: research
Learn Tab → Soldering Solar Cells (link to video on website as well?): https://www.instructables.com/id/How-to-Solder-Solar-Cells-Together/?scrlybrkr=e62c8e69
Flux pen-- to remove the excess oxidation
Add tabs to the back of the solar cells
Monocrystalline: more effective
Because of lower silicon purity, polycrystalline solar panels are not quite as efficient as monocrystalline solar panels. Lower space-efficiency. You generally need to cover a larger surface to output the same electrical power as you would with a solar panel made of monocrystalline silicon.
Polycrystalline: Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.
Reflection on Soldering
Pressure (very light-- don’t push just apply pressure as you go down the line)
Temperature (go to 5)
Keep it aligned ( another soldering pen/ pliers )
Use another soldering iron (that is not plugged in to keep it smooth)
Blue cap flux pen worked better
Does the bleeding of the flux pen affect the voltage of the panels?
Try and connect them? (thecracked ones- practice…)
Try soldering on the other side
TEST ON WEDNESDAY!!!!!!!!
