To convert the sun's energy into usable electricity, all photovoltaic solar cells rely on semiconductors. Light from the sun excites electrons in the semiconductor material, causing them to flow into conducting electrodes and generate an electric current. Since the 1950s, silicon has been the primary semiconductor material used in solar cells.

Now, perovskite materials have emerged as the most promising, efficient, and affordable semiconductor material for photovoltaic applications. Perovskites are a crystalline class of materials that are synthesised in a lab and are often applied as an active layer in the perovskite solar cells in the form of ink. Essentially, a specific formula of precursors is mixed together in a solvent to form ink. This ink is then deposited onto a substrate and sandwiched between different layers including electrodes to be made into a solar panel, as seen here:

Perovskite can better address some of the issues faced by silicon solar cells:

  • LESS WASTE. Perovskite solar modules are a few mm thick, compared to silicon solar panels which are tens of mm thick. The reduction of material required to make solar modules will by virtue reduce the waste generated.

  • HIGHER EFFICIENCY. In the last 12 years, perovskite has also made significant strides in efficiency. Perovskite solar cells were first created in 2009, with an efficiency of only 3.8 percent. In only 12 years, the efficiency has increased to more than 25%, and research continues to make leaps in efficiency! This means that, when compared to traditional solar panels, more power can be produced, allowing us to meet higher energy demands with clean, renewable energy.

  • EASE OF FABRICATION. Compared to silicon, solar panels made with perovskite require much less manufacturing energy and raw materials in their fabrication process. The fabrication of perovskite solar cells is relatively simple, meaning they could easily be fabricated all over the world.

  • MORE APPLICABILITY. Perovskite can also be thin and flexible, which improves its applicability. Imagine solar panels so thin and flexible that they can be supported by many structures and take the shape of whatever surface they are on. These panels could easily adopt the curve of the roof of a car or be used on the siding of a building.

Perovskite offers new photovoltaic technologies with the potential to be more efficient, with lower waste and carbon footprints, and with more applications than traditional silicon solar technology.

Interested in switching to perovskite PV technology?

Solaires is one of the industry's few organisations directly involved in the development of the perovskite value chain. We are developing a perovskite-based solar ink and a perovskite solar cell manufacturing process that would manufacture the next generation of solar cells.
