SOLAR CELL UNIT AND SOLAR CELL MODULE

摘要

A photovoltaic unit comprising photovoltaics for generating power by utilizing solar light and a bypass diode connected in parallel with the photovoltaics further comprises a reaction element adapted to react to a current flowing therethrough and connected in parallel with the photovoltaics and bypass diode and a blocking element connected in series with the photovoltaics. The reaction element is constructed such as to react to a current flowing therethrough when no current flows through the bypass diode while a reverse voltage is applied to the photovoltaics. The blocking element blocks a current of the photovoltaics according to the reaction of the reaction element.
