Thermal to electric conversion with diodes

Click For Summary
SUMMARY

Thermal current in diodes, quantified at 26 millivolts at room temperature, plays a crucial role in the conversion of heat to electricity. The discussion highlights the potential of quantum tunneling diodes, which have shown promising results in this area. However, the necessity of quantum effects for effective thermal to electric conversion is questioned, as traditional solar cells demonstrate efficient energy conversion without relying on quantum phenomena. The conversation emphasizes the efficiency of diodes in solar cells as a viable alternative for energy conversion.

There is well known phenomenon such as thermal current in diodes which is 26millivolts at room temperature.And it increases with temperature rise.How good are diodes in converting heat to electricity and what qualities should have diode for perfect heat to electricity conversion?I read that scientists have experimented with quantum tunneling diodes for this purpose and claimed to achieve some results.
But do they really need quantum tunneling effects?It seems to me that usual solar cells convert light into electricity in similar way and there is no need for quantum
effects.Diodes in solar cells look quite efficient and don't seem to be a serious limitation.

what "well known phenomena" are you referring to...thermal noise? other electrical components exhibit that...like resistors, capacitors,etc.
