Solar Cell Test
Fixture
If you are considering building your own solar panel, you might try building the
solar cell tester shown below. When constructing a solar panel it is important to
make sure that all the solar cells used in the panel be closely matched for their
short circuit current. One weak cell will lower the efficiency of the whole panel.
The system shown allows individual solar cells to be tested for their short circuit
current under a constant light intensity condition....

- Solar
PV cell Test Fixture
This is an illustration of a test fixture, which can be used to test individual
solar cells for short circuit current. Using a PIN photo diode and a control
circuit, the solar cells can be tested under constant light level conditions. A
halogen incandescent lamp is used as the light source. (added 7/06)

Scheme Detects Shorts - 07/08/99 EDN-Design Ideas: [Note: File contains
multiple circuits. Scroll to find this one.] When you manually assemble
complex boards, it's common to short-circuit adjacent component or IC pins.
Determining which section of the circuit you have shorted is not too difficult, but
finding the precise point.....(design idea added 2/06) |

Scheme provides High Side Current sensing for White LED Drivers - 02/19/04 EDN-Design
Ideas: White LEDs find wide use in backlighting color-LCD screens in most
portable devices, such as cellular phones, PDAs, and MP3 players. Multiple LEDs often
connect in series to ensure that the same current flows through every LED. To
forward-bias these LEDs, a voltage of 10 to 16V.....(design idea added 1/05) |
