Blackbody radiation is the wrong approach. If you are going to slap a PV panel onto a radioactive source then tune it for the emitted radiation rather than the blackbody heat. Radiation from nuclear decay should be very narrowband, allowing for a more efficient PV solution.
- perihelions 2y agoThere is no emitted radiation: the heat source self-absorbs its own alpha radiation and converts it into heat.
- angiosperm 2y agoArrayed as a thin film on a substrate, you can use the kinetic energy of the alpha particles directly for thrust. The substrate will need to dissipate some heat from nuclei emitted in the wrong direction.
