The lightweight nature of flexible PV modules makes them ideal for applications where traditional panels may be impractical.

The Technology Behind Flexible PV Modules

Flexible PV technology primarily relies on two types of materials: organic photovoltaic (OPV) and thin-film solar cells (such as cadmium telluride (CdTe) and copper indium gallium selenide (CIGS)). Each technology offers distinct advantages in terms of efficiency, production cost, and environmental impact.

Organic Photovoltaic (OPV) Technology

OPV technology employs organic materials to convert sunlight into electricity. These materials can be processed in various ways, making them adaptable for different applications. While OPV currently has a lower efficiency compared to traditional silicon-based cells, ongoing research and development aim to improve its performance.

Thin-Film Solar Cells

Thin-film solar cells are made by depositing one or more thin layers of photovoltaic material onto a substrate. This technology allows for the production of flexible and lightweight solar modules that can be integrated into various surfaces. For instance, CIGS panels have shown considerable promise in efficiency and cost-effectiveness.
