Three conceptual designs have been developed for hybrid solar-biomass/gas thermophotovoltaic (TPV) system for a non-intermittent power generation which can operate at relatively low TPV operating temperatures. TPV cells with lower band gap has been chosen for this conceptual hybrid device. The low band TPV cell generates electricity at longer photonic wavelength which corresponds a lower operating temperature. The development methodology is presented for a spectrally matched emitter which emits maximum photonic energy in the 600°C -1000°C temperature range with correspondingly lower photonic energy emission in the 0°C -600°C range. This approach for spectral control in TPV systems requires fewer system components.
