摘　　要：The ability of a structure in the form of a photovoltaic element with a built-in posistor layer based on a polymer nanocomposite with carbon filler being in direct thermal contact to protect against overvoltages was studied experimentally and by simulation.It was shown that the current and voltage on the reverse-biased p-n junction of the photovoltaic layer are limited and decrease from the moment when the temperature of this structure reaches values close to the tripping temperature of the posistor nano-composite to the low-conductivity state.The temperature of the photovoltaic layer has a value close to the tripping temperature of the posistor layer,which is equal to~125°C.The possibility of realizing protection against reverse electrical overvoltages and thermal breakdown of photovoltaic systems based on photovoltaic elements with built-in layers of posistor polymer nano-composites with carbon fillers was established.
