This paper demonstrates the electric energy generation of a concentrated combined
PV cell and a thermoelectric generator TEG system based on solar spectrum splitting.
The full spectrum is divided into two parts; bandga pspectrum (350 nm-1100 nm) which
is transferred to the solar cell and the above bandgap spectrum (1100 nm-4000 nm)
which is transferred to the TEG. An evaluation of the thermal and electrical performance
of the concentrated combined PV-TEG concept was performed. Temperature and efficiency
of the solar cell are evaluated in terms of concentration for full and splitted spectrum.
Full spectrum illuminated PV cell efficiency is decreased in high concentration levels
due to the high temperature values. The combined system efficiency is higher than
in case of standalone PV and TEG subsystems. The heat sink affects the concentrated
combined PV-TEG system where increasing the heat transfer coefficient increases the
combined system overall efficiency.
