摘要

这项工作探索了使用基于二氧化钒的玻璃临界热敏电阻的可能性，以提高太阳能电池光伏组件的可靠性并防止电热过载。采用基于二氧化钒和磷酸钒玻璃V2O5-P2O5的玻璃陶瓷材料作为热敏电阻元件，在70℃左右的温度下，电阻值突然变化1.5-2个数量级。已经确定所考虑的热敏电阻结构可以作为太阳能组件中的旁路元件。这些元件直接对过电压的存在和单个光伏电池的温度升高产生反应，并增加电阻，从而提高了整个太阳能电池阵列的可靠性。

Study on the application of glass ceramics based on vanadium dioxide as a bypass device in solar cells

The work explored the possibility of using glass critical thermistors based on vanadium dioxide to improve reliability and prevent electrothermal overloads in photovoltaic components of solar cells. Glass-ceramic materials based on vanadium dioxide and vanadium phosphate glass V₂O₅-P₂O₅ were used as a thermistor element, which abruptly change the value of electrical resistance by 1.5–2 orders of magnitude at a temperature of about 70 °C. It has been established that the thermistor structures under consideration can function as bypass elements in solar modules. Such elements react directly both to the presence of overvoltage and to temperature increase in individual photovoltaic cells with increased resistance, and thus provide increased reliability of solar array as a whole.
