Aguilar, Horacio Munguía; Maldonado, Rigoberto Franco; Navarro, Luis Barba – Physics Education, 2017
Charging a capacitor with a photovoltaic module is an experiment which reveals a lot about the modules characteristics. It is customary to represent these characteristics with an equivalent circuit whose elements represent its physical parameters. The behavior of a photovoltaic module is very similar to that of a single cell but the electric…

Aguilar, Horacio Munguía; Peña, Kassim José Mendoza – Physics Education, 2019
A simple and economical system that allows one to obtain the characteristic "I-V" curve in solar cells is presented. It is a computer-controlled system suitable as an instrumentation project for students who are learning about photovoltaic systems. This system is based on the use of an "R-3R" ladder circuit as a variable…
