1. Thermophotovoltaic generator converts
thermal radiation
directly into electricity with photovoltaic cells
A. Consists of a heat source, a radiation emitter, an optical focussing and filter system and special photovoltaic cells
1. Heat is re-radiated by the
emitter as light
2. Photovoltaic cells of gallim antimonide convert the radiation into electricity. The band gap is 0.7eV which is lower than silicon cells
3. This means that we can convert light which is further into the infrared spectral range
