Flexible solar panels are thin-film solar cells made of flexible materials. They are lightweight, bendable, and easy to install. They are suitable for special scenarios that are difficult to meet with traditional rigid photovoltaic panels.
1. Core structure and materials
A. Substrate material:
Flexible substrates are used instead of rigid glass to give the components flexibility.
B. Photovoltaic layer:
a. Amorphous silicon (a-Si): low cost but low efficiency.
b. Copper indium gallium selenide (CIGS): high efficiency, good weak light performance.
c. Cadmium telluride (CdTe): high efficiency, suitable for large-scale production.
d. Perovskite: emerging technology, laboratory efficiency exceeds 25%, but stability needs to be improved.
e. Organic photovoltaics (OPV): all solution processing, extremely light and thin.
2. Key features
A. Flexibility: bendable radius as small as a few centimeters, suitable for curved surface installation (such as roof, tent).
B. Lightweight: weighs only 200-500g/m², which is 1/10 of glass components.
C. Durability: impact and vibration resistance, some products have passed IP67 waterproof certification.
D. Weak light response: some materials (such as CIGS) can still generate electricity on cloudy days.
E. Light transmittance: can be made into semi-transparent components for building integration (BIPV).
