Summary

Solar energy is one of the most explored alternatives for generating clean and renewable energy nowadays. In view of the high cost of photovoltaic panels and the drop in photogeneration efficiency according to their useful life, it is necessary to explore different technologies so that solar energy contributes more and more to the world's energy matrix [1]. Both the obtaining of the electrical characterization parameters of the solar cell prototypes and the durability tests are carried out with very expensive electrical equipment. In this work, we developed a low-cost, automated device for carrying out current-voltage (I-V) measurements, capable of automatically obtaining characterization parameters such as: short-circuit current (ISC), open-circuit voltage (VOC), and the fill factor (FF). In addition to electrical measurements, the equipment is capable of obtaining environmental conditions such as humidity, temperature, and luminosity. All this data is sent to a “cloud”, using a spreadsheet as a database so that, after treatment, they are graphically displayed on a WEB page, making it possible to compare the efficiency between the cells connected to the equipment. Measurements and data manipulation are carried out autonomously every day at a time pre-established by the user. The equipment has the functionalities of an SMU (Source Measurement Unit), being developed from an ESP32 microcontroller. For the development of the voltage source, a DAC (Digital-to-analog converter) and an offset circuit are used to modulate the signal, making it possible to generate a voltage between -0.5 V and 2.5 V. To perform more sensitive current measurements, an ammeter was developed based on a configuration based on a shunt resistance, making it possible to determine the current indirectly through the shunt resistor with readings on the scale of nano Amperes. This equipment can be used both in the laboratory and for daily and automatic monitoring (indoor and outdoor) of different photovoltaic panels to check their performance according to environmental conditions and allow comparison between panels manufactured from different materials.
