The present invention discloses a backsheet of a solar cell. The backsheet of a solar cell comprises, sequentially from bottom to top, a bottom plastic layer, at least a first insulating layer, a conductive water-proof layer, at least a second insulating layer formed on the conductive water-proof layer, and a weather-resistant layer formed on the second insulating layer. The voltage-resistant ability of the weather-resistant layer is usually about one-third of that of the ordinary insulating layer and the weather-resistant layer is usually has the problem of pinhole which usually results in the defect of arc fail. Therefore, the second insulating layer, in the present invention, deposited between the conductive water-proof layer and the weather-resistant layer, can increase the voltage-resistant ability of the weather-resistant layer and to prevent the pinhole and the arc fail problem.

Backsheet of a solar cell

The primary objective of the present invention is to provide a solar module with a bimetal breaker, which comprises a solar module with terminal ribbons deposited on both sides of the solar module and inter-connecting ribbons extended and connected to the terminal ribbons, and a bimetal breaker being deposited on a joint of the terminal ribbon and the inter-connecting ribbon of the solar module. The bimetal breaker comprises a bimetal unit that is composed of two metal layers, and when the bimetal unit is heated, the bimetal unit will bend because of different thermal expansion coefficients and push the conducting terminals to separate from each other, so as to prevent the solar module from being damaged due to high temperature.
