Abstract In the field of thermoelectric power generation using semiconductors，how to utilize thermal energy
efficiently and enhance power generation efficiency is a current research focus．This study aims to enhance the
output power and efficiency of semiconductor thermoelectric power generation through the optimization of hot-
end temperature regulation，the development of an integrated data collecting platform，and the implementation
of a dual-chip series arrangement for a custom thermoelectric generator．Ｒesearchers investigate how hot-end
temperature gradients and semiconductor connection techniques affect output current，output voltage，and
maximum output power，which greatly enhances power production efficiency．The experimental results show that
at a hot-end temperature of 331 K，the maximum output power of the double-plate series configuration reaches
1．158 W，about 157% higher than the single plate(0．449 55 W)，and can stably drive low-power devices．
Meanwhile，the goodness of fit between the measured data and the theoretical model is 0．999 255，with a
maximum error of only 0．038 341．This research presents innovative methods for fulfilling educational needs，
exploring thermoelectric power generation in semiconductors，engineering small energy systems，and harnessing
waste heat．
