The invention discloses a foldable
solar power generation device which structurally comprises a left frame, an upper frame, a power connecting wire, a
power output wire, a
power output connector, a lower rotary block, an upper rotary block, a photovoltaic module, a right frame and a lower frame. The left frame is perpendicular to the upper frame, the power connecting wire is connected with the upper frame, the
power output connector is arranged at the
tail end of the power output wire, and the lower surface of the lower rotary block is attached to the lower surface of the upper rotary block. The foldable
solar power generation device is structurally provided with the photovoltaic module. When the device is started to perform
solar power generation,
sunlight penetrates through a tempered glass layer and upper-layer EVA
adhesive film to reach solar cells fixed to a TPT backboard through layer-layer EVA
adhesive film for photovoltaic conversion, the high transparency of the tempered glasslayer and the upper-layer EVA
adhesive film make
light energy absorbed efficiently, the
photovoltaic conversion efficiency is improved, the solar cells are sealed on the TPT backboard through the upper-layer EVA adhesive film and the layer-layer EVA adhesive film, and the service life is longer.
