Huawei flexible thin-film solar modules

What are thin-film solar-cell modules?

Thin-film solar-cell modules are lightweight and flexible as compared with modules built by traditional crystalline silicon cells. Moreover, thin-film cells may be easily molded into various shapes and sizes based on the need of a specific application.

How is a thin-film solar cell fabricated?

In general, a thin-film solar cell is fabricated by depositing various functional layers on a flexible substrate via techniques such as vacuum-phase deposition, solution-phase spin-coating, and printing. A flexible substrate provides mechanical support and environmental protection of the whole cell.

Are thin-film solar cells environmentally friendly?

Cu-based thin-film solar-cell materials are considered environmentally friendlier than CdTe and Si-based solar cells. They are chemically stable and have a decent PCE of around 19% on module level . They can be fabricated using various techniques, which include solution processing and vacuum deposition ranging from low to high temperature .

What are flexible solar modules?

Flexible solar modules are extremely demanding energy solutions for commercial products, where the specific power, total weight, and mechanical impact strength are crucial . One such example is the integration of semi-flexible solar panels into the roofs of boats as a secondary source of charging.
