Outline of Final Research Achievements

First, an infrared camera image and a burned image were obtained by reproducing the phenomenon in which a high temperature HS of 250 °C was generated partially in a single cell module. Next, a model for simulating the temperature distribution of the solar cell is modeled on MATLAB, an attempt is made to reproduce the temperature distribution and the temperature rise graph, and the temperature distribution with the accuracy of several tens of percent with sufficient accuracy for detecting the presence or absence of high temperature HS I confirmed that prediction is possible. The model expressing the emergent phenomenon reproduced the phenomenon in which scorching expands using the automaton method. We also collected basic data on the temperature characteristics of avalanche voltage Va from fundamental experiments of heating by single cell solar cell and hotplate and confirmed that there is a strong correlation between Va and short-circuit current Isc of about 1 V change per 25 °C.
