Application of Solar Cells for Daytime Weather Study

The electric current is generated by the solar cell when the solar radiation is incident onto the solar cell. The intensity of the incident solar radiation can control the amount of generated electric current. In daytime, the variation of intensity of the incident solar radiation mainly comes from the cloud over the solar cell. It causes the variation of generated electric current. This phenomenon serves the new way to use the solar cell for meteorological purpose. In the period of experiment days, the results showed that the variation of generated electric current might be plausible to the daily weather condition. On the sunny day, the generated current was small fluctuation and had high level. Otherwise, a small fluctuation with low level one was appear on the cloudy day. On the rainning period, the generated current could drop down more than 3000 mA when compared with the sunny period.
