There are photovoltaic IR cells which when combined with the
more standard visible solar cells can and do exceed the 13%
conversion efficiency to DC output as they are in affect twice
the collecting area.
Using visible and invisible light to generate electricity.

Not using an IR sensor. Those devices, as MPilch said, require power input, and they produce a signal when they detect infrared.

Thermoelectric generators use the Seebeck effect to convert heat energy directly into electricity.

NO.

IR sensors don't produce an electrical current when they are in the presence of IR radiation. They need current flowing through them and then they output a different current based on the presence of an IR source.

Well, thermoelectric generators do produce electricity from heat input, but they aren't sensors.
