A no-load voltage of a photovoltaic cell as a function of irradiation intensity

Abstract

Modern technologies are increasingly being applied in teaching in primary and secondary schools. Therefore, it is very important to provide students with the opportunity to actively work with technology. We have tried to suggest some topics for tasks that pupils can measure independently in physics lessons, process the data and draw conclusions from their measurements. We used a 3D printer, Vernier sensors, a VEX IQ robotic kit and an Arduino single-board computer. All the ideas are detailed in the thesis. For each task prepared in this way, there is a theoretical part, which the students study before the laboratory task, then the assignment of the actual laboratory work (task, tools, detailed procedure) and the possible results of the measurements. Methodological instructions for teachers are an integral part of the topics. In this article, we would like to describe the laboratory exercise "Determination of the breakdown voltage as a function of irradiance" as an example of the topics. A total of seven materials were created for this topic in the framework of the above-mentioned thesis - a method sheet for teachers and six annexes. Due to the scope of the article, it is not possible to include all the created materials, so we include only selected samples.
