Recently, solar panels have become one of the most desirable sources renewable electrical energy, and thus requirements for their reliability, in particular to maintain basic functional properties at elevated temperatures, are increasing. The element batteries is photovoltaic converter. Until now, degree degradation ways protect converters during overheating corresponding real situations exploitation, not sufficiently studied. In this paper, authors study important problems arising development circuit-technical devices protection against electrothermal overloads, namely, problem effect on properties. Primarily, connection with perspective using electronics improve reliability system battery. particular, resettable fuses based polymeric nanocomposites carbon fillers such elements electronics. One difficulties direct application that they a switching temperature exceeds standard operating range modern converters. paper presents investigations results current-voltage volt-watt characteristics single-crystal silicon batteries, which undergone heat treatment (up 150°C) different time intervals 6 hours) under lighting conditions dark mode open- short-circuited states. method fixing deviations parameters (i.e., open-circuit voltage, short-circuit current maximum power) from nominal values was used analysis. It has been established investigated ranges there no significant changes main silicon.
