The invention relates to a photovoltaic module and an unmanned sailing boat, and aims at overcoming the problems of heavier weight and lower corrosion resistance of the photovoltaic module. The photovoltaic module is composed of an ETFE film, a first packaging adhesive film, a solar cell, a second packaging adhesive film, a thin aluminum substrate, a third packaging adhesive film and a photovoltaic backboard which are sequentially arranged in a stacked mode. The photovoltaic assembly is packaged with the thin aluminum substrate through the ETFE film, is high in flexibility, can be bent, and can be cut to customize various shapes. The weight is low and the thickness is low; and the thin aluminum substrate prevents water vapor and oxygen from permeating into the layer where the solar cell islocated from the back surface of the photovoltaic module, so that the water resistance, salt spray corrosion resistance, weather resistance such as aging resistance, use reliability and the like of the photovoltaic module are improved.
本发明涉及一种光伏组件及无人帆船,用于缓解光伏组件较重及耐腐蚀性能较差的问题。其中,光伏组件由依次层叠设置的ETFE膜、第一封装胶膜、太阳能电池片、第二封装胶膜、薄铝基板、第三封装胶膜和光伏背板构成。光伏组件通过ETFE膜与薄铝基板封装,柔性好,可弯曲、可裁切定制各种形状;重量轻,厚度薄;且薄铝基板从光伏组件的背面防止水汽、氧气渗入太阳能电池片所在层,提高了光伏组件的防水、耐盐雾腐蚀能力,以及抗老化等耐候性与使用可靠性等。
