Fig. 6From: Research on mathematical model and calculation simulation of wireless sensor solar cells in Internet of ThingsMeasurement curve of photovoltaic power generation characteristics. a I-V curve which means the current-voltage curve. The x-axis is the output voltage and the unit is volt. The y-axis is the output current and the unit is ampere. The two curves represent the current under different light intensity and different temperatures. b P-V curve which means the power-voltage curve, The x-axis is the output voltage and the unit is volt. The y-axis is the output power and the unit is Watt. The two curves represent the power under different light intensity and different temperaturesBack to article page
