Investigating the efficiency of a photo diode - capacitor system.

A laboratory experiment is presented that examines a scheme of charging a capacitor by means of a photodiode illuminated by an LED lamp at an angle of 00. A number of functional analyzes were made between illuminance, luminous flux, generated voltage, relaxation time, light and electrical energy. The efficiency under different lighting conditions was analyzed and the efficiency of the system was determined. A mathematical algorithm for calculating the physical characteristics used has been compiled. The laboratory experiment was developed in order to be used in a physics laboratory practicum in the sections optics and electricity. The considered analytical methodology can be used to analyze photovoltaic systems and improve their efficiency. [ABSTRACT FROM AUTHOR]
