Silicon solar cell current with and without illumination
by an infrared source, the signal from a television remote control.

Infrared emitting diode (left) illuminates infrared
detector (right). With illumination the detector resistance drops
as does the voltage measured across the detector.

Remote control infrared source illuminates infrared
detector (right). With illumination the detector resistance drops
as does the voltage measured across the detector.

Polyethylene terephthalate (PETE) absorbs some of
the 925 nm illumination of the infrared emitting diode. Two thicknesses
absorb more than one thickness. The detector resistance increases
as does the voltage measured across the detector.

Current through a nichrome wire heats the wire.
