Objective
Objective

  • For this flight we did not intend to use the cells as a source of power

  • Research purposes - further our knowledge of solar cells

  • Collect voltage data from flight

  • Possible energy source for the payload components for future flights.


Types of solar cells
Types of Solar Cells

Polycrystalline solar cells

Brittle

Would not last throughout our flight


Types of solar cells1
Types of Solar Cells

Amorphous Silicon Solar Cells

5 V

Affordable

Easy to wire


Mounting
Mounting

2 on lid of payload

1 on side of payload

Plexiglas used for protection.


Flight results
Flight Results

  • First launch was on November 27, 2009 in Gila Bend, AZ recovered South of Phoenix

  • Successful Flight – No damage


Flight results1
Flight Results

Peaked at 1 Volt instead of 5 Volts.

Solar Cell 1: Mounted on side.

Solar Cell 2 & 3:Mounted on lid.


Flight results2
Flight Results

Combined data of the three solar cells.

Red and Green indicates top solar cells.

Blue indicates side solar cell.

Peak at 1 volt.


Future goals
Future Goals

  • Add a resistor to drop down voltage readings.

  • Complete another flight with modified solar cells.

  • Obtain better results.
