3. How Transparent Solar Panels Work
Photovoltaic Technology in Transparent Panels
At the core of transparent solar panels is the photovoltaic (PV) effect—the process by which sunlight is converted into electricity.
In transparent panels, the PV cells are engineered to capture a portion of the light spectrum while allowing the rest to pass through.
This selective absorption ensures that enough light penetrates the window to illuminate interiors naturally, reducing the need for artificial lighting.
Types of Transparent Solar Panels
There are primarily two types of transparent solar panels:
- Partially Transparent Panels: These panels allow some light to pass through while absorbing the rest for energy generation. They are often used in applications where partial transparency is acceptable, such as in shaded window areas or façades.
- Fully Transparent Panels: Designed to let nearly all visible light pass through, these panels are ideal for windows where maximum transparency is desired. However, achieving high transparency often means sacrificing some efficiency in energy production.
Each type has its unique applications and efficiency levels, catering to different architectural and energy needs.
