Overview

The TP-SCT-2 solar cell characteristics and application experimental instrument simulates sunlight through a tungsten halogen lamp, irradiates it onto a solar panel to generate electricity, and then measures the irradiance of sunlight through an illuminance meter to measure the output characteristics of solar cells (monocrystalline silicon, polycrystalline silicon, amorphous silicon) under illumination and obtain the corresponding short-circuit current (1SC), open circuit voltage (U0C), output power Pmax, and fill factor FF. At the same time, it also adds application experiments such as solar cell output, charging of energy storage devices, and load.
