Contributions to the design and construction of characteristic curve tracers for photovoltaic devices

Tracing the characteristic I-V curve of any photovoltaic device is the essential experiment that allows us to obtain reliable information about its state and behavior. Therefore, it must be part of the practical content in any Bachelor's, Master's or PhD degree that teaches the students in the photovoltaic systems engineering field. This paper presents the progress-achievements of two research groups -from Argentina and Spain- in the design of electronic prototypes or ad-hoc systems that carried out this experiment and which have subsequently been integrated into teaching practices. In addition, this knowledge has been incorporated into the research area in which the groups are involved.
