What are transparent PV modules?

Transparent photovoltaic (PV) modules are innovative solar cells that allow for electricity generation while letting light pass through, making them ideal for use in windows, facades, or vehicles. This technology offers a perfect solution for urban environments where space is limited. They combine aesthetic elements with functional benefits and are increasingly seen as a forward-looking solution for sustainable energy generation.

What exactly are transparent PV modules?

Transparent PV modules are solar cells that allow visible light to pass through while absorbing invisible light, such as infrared, to generate electricity. These modules achieve transparency values of 45 to 70% and have an efficiency of 5–10%. They are made from advanced materials such as organic photovoltaics (OPV), dye-sensitized solar cells (DSSC), or perovskite solar cells, which specifically utilize wavelengths outside the visible light spectrum. This technology offers a unique advantage: it allows transparent surfaces to be used for power generation without compromising light transmission or visual appearance. DRBO Greenenergy offers this technology in combination with efficient energy storage systems such as the SunLit systems to maximize energy self-sufficiency.

How do transparent PV modules work?

Transparent PV modules absorb UV and IR light and allow visible light to pass through. The modules consist of transparent substrates like glass or films, on which layers that absorb UV and IR light and generate electricity are located. These layers include materials such as ITO electrodes and special NIR-sensitive substances. The generated electricity is routed via transparent anodes and cathodes without impairing vision or light incidence. DRBO Greenenergy offers bidirectional inverters that enable efficient grid integration and thus optimize self-consumption.

What are the advantages of transparent PV modules?

Transparent PV modules offer numerous advantages, especially in urban environments where roof space is scarce. They enable windows and facades to be used as power sources, so the entire building envelope contributes to energy generation. The biggest advantage is the combination of energy generation and light transmission, which represents an ideal solution in urban areas. This technology can also be used in greenhouses and greenhouse walls, as it promotes light transmission while generating energy. By combining them with energy storage systems like those from DRBO Greenenergy, the yield is significantly increased and energy self-sufficiency is boosted to up to 70%.

What are the disadvantages of transparent PV modules?

A significant disadvantage of transparent PV modules is their lower efficiency compared to traditional, opaque solar modules. While standard modules can achieve efficiencies of 20%, the efficiency of transparent modules is usually only between 5 and 10%. Higher production costs for transparent layers and a shorter lifespan compared to classic solar modules (15–20 years) are also challenges. However, DRBO Greenenergy offers a solution in the form of reconditioned modules, which represent a more cost-effective alternative without sacrificing performance.

How are transparent PV modules installed?

The installation of transparent PV modules is relatively simple and can be mounted directly on existing windows or laminated between glass panes. These modules can either be affixed as a film to the glass surfaces or permanently installed. DRBO Greenenergy offers practical complete sets for this, including mounting brackets, cables, and microinverters to facilitate installation. These sets are particularly suitable for tenants as they can be removed without leaving residue. Installation only requires cleaning the window surface, attaching the modules, and connecting the inverter.

Can transparent PV modules be combined with storage systems?

Yes, transparent PV modules can be excellently combined with energy storage systems like those from DRBO Greenenergy. This allows the generated electricity to be stored and used as needed to maximize the self-consumption rate and minimize dependence on the public power grid. Surplus electricity can be stored in the SunLit storage units and made available for later use. This integration not only offers efficient use of the generated energy but also reduces operating costs.

Why are transparent PV modules forward-looking?

Transparent PV modules offer a forward-looking solution for integrating solar energy into existing buildings and urban landscapes. Their ability to let light through while generating electricity makes them a promising technology for Building-Integrated Photovoltaics (BIPV). The market for transparent PV modules is growing by 25% annually, and the development of perovskite solar cells could significantly increase the efficiency of these modules in the coming years. DRBO Greenenergy is proud to have included this technology in its portfolio, thereby making a decisive contribution to the decentralized energy transition.
