It adopts high-efficiency crystalline silicon solar cell technology and independently developed polymer composite materials, achieving a new type of crystalline silicon photovoltaic module that is glass free, lightweight, and thinned. The weight of flexible photovoltaic modules can be as light as 2.8 kg/m2, which is only 30% of traditional photovoltaic modules. The thickness can be reduced to less than 2 mm, and the shape and size can be adjusted to achieve customized design and production, which is convenient for transportation and significantly reduces transportation costs.
