Hey everyone, Revision 0 of the version 0 "Solar Module" is done, pending a Google Hangout with Alta Devices, the folks who make our solar cells, which will most likely change everything ;)
http://github.com/oresat/solar/ Left to figure out is how we: 1) Adhere the solar module to the PCB. They're suggesting either 3M 966 adhesive tape, or Dow Corning 93-500 "space grade" silicone. I'm leaning towards the tape, but we'll see. 2) Attach the metal tabs to the PCB. Turns out we can't solder to the tabs, that'll kill the cells (?). So we should apparently use conductive adhesive, but which one? And how much? and where on the tabs? Apparently there are some tricky issues here. 3) Cover the cells. The bare modules need to be covered with some kind of cover glass or other protection. We'll discuss this all on a Google Hangouts with them - I'll let everyone know when that is. I think at least Austin and Calvin should be on that call, too, although everyone's welcome to listen in. Have a few more ME types on the call might be a very good idea, too.
