Solar photovoltaic conversion is an approach for the direct
conversion of solar radiation to electric power. The spectrum
exergy of thermal radiation is derived on the basis of the
definition of spectral radiation exergy intensity. By taking the
model of a photovoltaic conversion process as an example, the
present paper studied the conversion of solar photovoltaic from
the view point of exergy analysis, and analyzed the distribution
of spectrum exergy efficiency of solar photovoltaic conversion
segments in photovoltaic conversion process. All in- and
outgoing fluxes in the thermodynamic balance equations for
spectrum energy and exergy must be known to evaluate the
spectrum efficiency of this energy conversion process. The
calculation procedure to obtain the spectral energy, and exergy
fluxes is described. The energy flow diagram and the exergy
flow diagram at given wavelength are described respectively.
The results show that the spectral utilization for solar
photovoltaic conversion is with promising.
