Part of the book series: Green Energy and Technology ( (GREEN)) Current voltage ( I-V) characteristic of illuminated photovoltaic (PV) cell varies with temperature changes. The effect is explained according to the physical theory of solids. The higher the temperature, the lower the open-circuit voltage and the higher the short-circuit current.
Optimal operating points on I-V characteristics at two temperatures Figure 8 shows the volt-ampere characteristics of an illuminated PV cell based on crystalline silicon as a function of temperature at constant illumination. It can be seen that the short-circuit current increases with increasing temperature, but that open-circuit voltage drops.
The operating temperature plays a key role in the photovoltaic conversion process. Both the electrical efficiency and the power output of a photovoltaic (PV) module depend linearly on the operating temperature.
Solar cell performance decreases with increasing temperature, fundamentally owing to increased internal carrier recombination rates, caused by increased carrier concentrations. The operating temperature plays a key role in the photovoltaic conversion process.
Coventry et al. analyzed the temperature change of a single PV system. The internal temperature of the cell showed that there was a temperature difference of up to 287.15 K between the middle and the edge of the cell. The uneven illumination strongly affects the temperature distribution on the SC.
In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.
