Abstract: In this paper, the temperature measurement probe is directly installed on the hot spot on the surface of the photovoltaic cell by combining the fluorescent optical fiber temperature measurement technology and the feedforward control method and more energy is obtained on the surface area. The "application bottleneck" that the hot spot temperature on the surface of the solar photovoltaic cell module is difficult to directly measure is solved and the power generation efficiency of the photovoltaic cell module module is improved as well.

Key words: photovoltaic cells, generating efficiency, optical fiber temperature measurement, feedforward control
