Saule Technologies printed solar cells: Revolutionary energy

Since the visible threat of global warming, the world has been focusing on the use of alternative green energy. This redirection has sparked the creation of a revolutionary alternative source of energy. 

Solar energy is not a new concept, but the way Olga Malinkiewicz has transformed this technology is something we all should look out for. Saule Technologies was founded in 2014, and in that year, the entrepreneur found a way to print solar cells on flexible foils. This small change has allowed them to redefine the world of renewable energy and has broadened the utilization of solar energy.

What are perovskite solar cells?

perovskite solar cells

A perovskite-structured chemical serves as the light-absorbing material of a perovskite solar cell, which is a kind of solar cell that turns sunlight into energy. The material’s unique three-dimensional crystal structure is referred to as “perovskite” in this context.

Perovskite-structured materials serve as the active layer in perovskite solar panels, a type of solar photovoltaic technology that turns sunlight into electricity. The material’s unique three-dimensional crystal structure is referred to as “perovskite” in this context. Methylammonium lead trihalide is the perovskite substance that solar cells use most frequently.

How are perovskite solar cells made

Saule Technologies is a company that specializes in lightweight, flexible perovskite solar cells that may be incorporated into windows and building materials, among other surfaces. Perovskites are printed on polymer films using inkjet technology. These solar cells are thin and versatile and have a high power-to-weight ratio.

This is how the solar cells are made:

  • Materials used: The absorber materials’ crystal structure (ABX₃), in which X is an anion and A and B are cations, is where the word “perovskite solar cell” originates.
  • Spin-coat: Chemicals are deposited onto a substrate using spin-coating.
  • Spraying: Applying chemicals by a spray technique is called spraying.
  • Painting: The term “painting” describes the process of applying perovskite material to the substrate during crystallization, which forms the perovskite layer.

Because they are simple to apply onto surfaces, perovskite cells are attractive to markets looking for flexible, lightweight, and non-uniform solar energy. In Saula, robots are responsible for the inkjet and other procedures in solar cell making. 

What makes these different?

They have broken the dimensions for use. While we have only seen solar cells on panels, the use of perovskite is diverse. These films are flexible enough to be used on almost every surface. Their translucent look helps blend the solar cells and gives the installation a clean finish. 

However, it is not just their aesthetics and versatility, perovskite also has a high power-to-weight ratio. It is resistant to harsh climatic conditions.

What are the applications of perovskite solar panels?

Building Integrated Photovoltaics (BIPV)

Building Integrated Photovoltaics (BIPV)


By integrating perovskite solar panels into structural elements like windows, facades, or roofing, it is possible to produce electricity and fulfill structural requirements at the same time. This type of renewable energy is skillfully incorporated into the architecture of the building.

Building-Attached Photovoltaics (BAPV)

Building-Attached Photovoltaics (BAPV)

Like BIPV, BAPV involves the attachment of perovskite solar panels to already-existing structures to add a sustainable energy source without taking up more space.

Internet of Things (IoT)

Perovskite solar panels can be used to supply electricity to gadgets within the IoT network. They are appropriate for compact, portable electronic equipment that can benefit from renewable energy sources due to their flexibility and lightweight.

They aim to change buildings and use renewable energy. They are striving towards lowering the carbon footprint by using green energy. They are doing their best to reverse the effects of global warming and we should follow their lead. 

We need to lower the use of non-renewable energy and switch to the use of renewable energy. This also means supporting and promoting brands and entities that use alternative energy for production.
