Temperature changes of I-V characteristics of PV cells as consequence of the Fermi energy level shift
Original language description
I-V characteristic of illuminated PV cell varies with temperature changes. The effect is explained according to the solid state theory. The higher temperature, the lower open-circuit voltage and the higher short-circuit current. This behavior is explained on the basis of band theory of the solid state physics. The increasing temperature causes a narrowing of the forbidden gap and a shift of the Fermi energy level toward the center of the forbidden gap. These both effects lead to a reduction of the potential barrier in the band diagram of the illuminated PN junction, thus to decrease of the photovoltaic voltage. In addition, the narrowing of the forbidden gap causes higher generation of electron-hole pairs in the illuminated PN junction and short-circuit current increases.
