Description	The problematic can be put in short as follows. The photovoltaic cell is in essence a large-surface semiconductor diode working in the generator mode. Its volt-ampere characteristic has limit quantities, which give the magnitude of open-circuit voltage and the value of short-circuit current. These quantities vary in dependence on the change in solar intensity and in cell temperature. Multiplying the instantaneous values of voltage by the instantaneous values of current we obtain the power characteristic. The highest point of this characteristic represents the maximum value of potential power that the photovoltaic cell can supply to the load under given operating conditions. If we want to obtain this maximum power, the voltage across the electrical appliance must equal exactly the optimum voltage. With prolonged solar intensity or impaired cell-cooling conditions the cell surface temperature increases to as much as 60 C. With such elevated temperatures there is a change in the electrical properties of The problematic can be put in short as follows.
