# short circuit current open circuit voltage fill factor

Open-circuit voltage (abbreviated as OCV or VOC ) is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals. The influence of these elements upon cell performance in areas such as short circuit current density (Jsc), open circuit voltage (Voc), and fill factor (FF) was examined based on the equivalent circuit. This is the ratio of the maximum power to the product of the open circuit voltage and short circuit current: The higher the fill factor the better. As a general rule, commercial PV cells will have a fill factor greater than 0.7. Using this function and the experimental results, we reviewed the temperature effects and realized that increasing temperature leads to voltage decrease of open circuit as well as reverse saturation current of the first diode and also results in increase of efficiency, filling factor, short-circuit current If the fill factor is 55 , what is the maximum power that can be drawn from this photodiode?
