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?)
NJ conference
Livestream race in the presentation?
Flying drone
Maybe link it to the website too?
Logo presentation:
Add sun(s)
Website and Emails
Assembly/ Presentation post-Christmas break…
Solar Cells:
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
STEPS:
Flux pen-- to remove the excess oxidation
Add tabs to the back of the solar cells
Solder
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
Next Steps:
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!!!!!!!!
