System for electrical characterization in semiconductors for application in solar cells

This work describes a made home system for measuring electrical properties in solar cells and semiconductor material for photovoltaic application, in an environment with low electrical noise and controlled radiation. It consists of a Faraday cage connected to a source measuring unit (SMU) KEITHLEY 2450, which gets the characteristic curve in solar cells and the resistivity in thin sheets of semiconductor material. The system includes a halogen lamp that allows taking measurements at controlled irradiation. As preliminary results, we have obtained Ι-V curves for solar cells and thin film resistivity at different temperatures in the same system.
