Have you ever wondered if solar panels could be transparent like glass? What would they cost, and who makes transparent solar panels? These questions might sound like a peek into the future. But they’re actually about a technology here now: transparent solar panels.

This invention transforms buildings, greenhouses, and pergolas into sources of power.

In this blog, we’ll explore how these clear solar panels work, compare them with regular solar panels, and look at the latest research. We’ll also discuss their prices and unique benefits.

Let’s discover how transparent solar panels work for solar energy.

What Are Transparent Solar Panels?

Transparent solar panels, also known as bi-facial solar panels, allow light to pass through while still generating electricity. Solar panels with transparency absorb light from both sides, unlike opaque solar panels. In this way, they can generate electricity from both direct and indirect sunlight.

How Do Transparent Solar Panels Work?

What is the working principle of transparent solar panel? Transparent solar panels use photovoltaics (PV) to convert light into electricity. A PV cell consists of a semiconductor, usually silicon, sandwiched between two layers of conductive material. The PV cell creates electricity when light hits it and knocks electrons from the semiconductor atoms.

In traditional solar panels, the PV cells cover with glass. This serves to trap light and direct it into the cells. Transparent solar panels replace the glass layer with a transparent material, such as plastic or glass. This allows light to pass through to the PV cells.

PV cells in transparent solar panels absorb light from both sides. PV cells are coated with transparent conductive materials like indium tin oxide (ITO). In this way, light passes through the cells and is absorbed at the bottom.

What is Bi-Facial solar panels?

Bifacial solar panels are another type of transparent solar panel that is gaining popularity. The panels have photovoltaic cells on both sides. So they can absorb sunlight from both sides. Traditional solar panels do not absorb light from both sides, so they are more efficient.

Bifacial solar panels are also available in transparent materials, making them an aesthetic option for incorporating solar energy.

Advantages of transparent solar panels

Transparent solar panels are an innovative form of solar power. These solar panels allow light to pass through but still generate electricity. This means you can use them in more places, like windows, skylights, car roofs, and even on gadgets.

They look good because you can hardly see them, so they’re great for places where you don’t want to block the view.

As a result, they reduce energy usage and costs. These panels can also make indoor lighting nicer and cheaper as technology improves.

Right now, they’re not as efficient as regular solar panels. They should become more competitive and better with ongoing research.

Types of transparent solar panels

There are two main types of transparent solar panels: crystalline silicon and thin film.

Crystalline silicon panels are made from silicon wafers, like traditional solar panels. However, they are much thinner and use a transparent conductive oxide layer to allow light to pass through.

Thin-film panels, however, use thin layers of photovoltaic material sandwiched between glass or plastic. The use of these panels into building materials because they are flexible and lightweight.

Applications of transparent solar panels

There is a wide range of potential applications for transparent solar panels. That includes electronic devices, buildings, and even vehicles. Here are a few of this technology’s most promising applications.


One of the most exciting uses for transparent solar panels is in greenhouses. Solar panels can be used as a roof, absorbing solar energy while letting light pass through to the plants.

Greenhouses transparent solar panels

This provides a source of energy for the greenhouse and regulates its temperature. The panels can also be used to create a microclimate within the greenhouse. This allows for the growth of plants that may not thrive in the surrounding environment.


Transparent solar panels are also suitable for use in residential and commercial buildings. They provide clean energy and remain transparent, even when incorporated into windows, skylights, and facades.

Transparent solar panels are great for tall buildings where regular panels might not fit. They can also lower energy costs, making them both cost-effective and eco-friendly.

Electronic devices

Transparent solar panels are available on smartphones and tablets. They let these devices charge while you use them. This could get rid of charging cords and save energy. It also means less charging for longer battery life.


Transparent solar panels can be used in electric cars too. They can go on windows and roofs to make clean energy. This could help cars go further without needing to charge often. It also makes driving more eco-friendly.

Power for Field Operations:

Solar panels are light, strong, and easy to maintain. This makes them great for remote or dangerous places. They work even in low light, perfect for military or emergency situations where steady power is key.

Solar-powered spacecraft:

Spacecraft and satellites use clear solar cells to get power from the sun, high above Earth. These cells change sunlight into electricity for running spacecraft systems. They work even better in space than on Earth, so they’re often used there.

Challenges and limitations

Transparent solar panels have their benefits, but they also face some challenges. They aren’t as efficient as regular, opaque solar panels because of their poor light capture. 

They’re also more expensive due to the cost of the materials used, but this might decrease as the technology improves. Also, they’re not as tough as traditional panels, making them unsuitable for areas with extreme weather or pollution.
