We report the study of the temperature dependance of the performance electronic parameters of an N-P solar cell by considering as model, the columnar cylindrical orientation associated to the dynamic junction velocity (SF) concept. We presented the photocurrent-photovoltage (I-V) and Power-photovoltage (P-V) characteristic curves. The short-circuit photocurrent (I sc ), the open circuit photovoltage (U oc ), the fill factor (FF) and the efficiency (η) are linearly dependent on the temperature. The temperature coefficients (T-coefficient) relative to the short-circuit, open-circuit photovoltage and efficiency are calculated and the comparison with data from the literature showed the accuracy of the considered model.

“…For the same conditions, when the grain size (g) increases, Sf 0,u and the shunt resistance decreases and increases, respectively. This situation corresponds to less recombination and the real operating point of the solar cell roll away of the initiating operating short-circuit condition studied in [16].…”

“…For a fixed external load, corresponding to a specific value of Sf j , Sf 0,u increases with the grain boundary recombination (Sgb). This leads to the lower shunt resistance (R sh ) and to the initiating short-circuit condition quickly reached [16]. For the same conditions, when the grain size (g) increases, Sf 0,u and the shunt resistance decreases and increases, respectively.…”

This work, based on the junction recombination velocity (Sfu) concept, is used to study the solar cell's electric power at any real operating point. Using Sfu and the back side recombination velocity (Sbu) in a 3D modelling study, the continuity equation is resolved. We determined the photocurrent density, the photovoltage and the solar cell's electric power which is a calibrated function of the junction recombination velocity (Sfu). Plots of solar cell's electric power with the junction recombination velocity give the maximum solar cell's electric power, Pm. Influence of various parameters such as grain size (g), grain boundaries recombination velocity (Sgb), wavelength (λ) and for different illumination modes on the solar cell's electric power is studied.

In this paper, we extend the concept of back surface recombination through a study of a silicon mono facial solar cell in static regime and under polychromatic illumination. Back surface recombination velocities noted Sbe , Sbj and Sbr are determined for which respectively we derived, the power, the fill factor and the conversion efficiency, that become constant whatever the thickness of the solar cell. We have then obtained the expression of the minority carrier's density in the base from the continuity equation. We then have determined the photocurrent density, the photo voltage, the power, the fill factor and finally the conversion efficiency.
