Abstract: This work aims at the automated I-V characterization of solar cells using a power MOSFET based electronic load and a PIC microcontroller based interfacing circuit. The load circuit used is a dynamic electronic load that uses a power MOSFET biased in its linear region. A unity gain Op-amp is used to provide the appropriate voltage to the gate of the MOSFET so that it acts as a varying resistance, driving the current in the circuit. A microcontroller (PIC16F873) based circuit was used to measure the current and voltage levels, digitize it, and transmit them over RS232 cable using the USART protocol. An open-source cross-platform software for plotting the I-V curve was also developed. The program uses the OpenGL API to display primitives. [ABSTRACT FROM AUTHOR]
