NEXT GENERATION Photovoltaics TECHNOLOGY

Perovskites are the Future of Photovoltaics

As one of the fastest growing and most promising innovations in the PV energy sector, we believe perovskite PV modules are leading the way toward a more sustainable energy future. That's why we are committed to commercialising this cutting-edge technology through advanced roll-to-roll production techniques. With this approach, we can 'print' perovskite modules capable of harnessing energy in a variety of lighting conditions, even where it hasn’t been viable in the past.

Our PV Technology is ground breaking

As global leaders in next-generation PV technology, we've achieved a ground breaking milestone with a world-record efficiency of 38.5% in low-light conditions (1000 lux). This remarkable performance opens the door to powering small electronics and IoT devices with reliable and renewable energy, even in dull or artificial lighting.

Specially tuned ambient PV modules, optimized for low indoor light can make a difference by providing the ability to efficiently harvest indoor light. This innovation has the potential to eliminate millions of disposable batteries, reducing e-waste and supporting a cleaner, more energy-efficient future.

Perovskites are the future of Photovoltaics

Perovskites are a class of compounds with the same crystal structure (ABX₃). They can be made from a variety of elements, but the structure was originally found in a mineral called calcium titanate (CaTiO₃). A large number of metallic elements are stable in the perovskite structure, and there are thousands of known perovskites with different properties. They have been used since the 1950s in sonar (Sound Navigation and Ranging) applications.

In 2009, researchers discovered that some perovskite materials were excellent at absorbing sunlight and converting it into electricity. A tuneable band gap makes perovskite PV cells extremely efficient in a wide range of lighting conditions, including artificial, natural, direct, and indirect light.

Perovskite efficiencies now match silicon in full sun and produce more energy throughout the day, as they continue to generate power from dawn to dusk, and under cloudy conditions. Perovskites are 100x thinner than traditional silicon PVs, flexible, lightweight, and can be made partly transparent. This makes them suitable for a variety of surfaces and structures, where traditional PVs haven’t been viable.

The low-temperature manufacturing process, including roll-to-roll printing, enables perovskites to be produced very efficiently. The low material and energy costs, mean perovskite cells may reach prices three times cheaper than traditional silicon cells. Compared with silicon and other PV technologies, perovskite PVs are better for the environment due to their low-temperature manufacturing process (120°C vs. over 1,000°C for silicon) and the ability of PSC modules to be fully recycled, returining 99% of materials back into the manufacturing process to make new panels.

The future of Photovoltaics energy is roll-to-roll manufactured

Halocell’s modules employ roll-to-roll manufacturing, a process that has the potential to be rapidly scaled.. This continuous , high-throughput process allows for coating flexible substrates with thin films of photovoltaic material. Roll-to-roll manufacture will facilitate low-cost, high-volume production of PSCs for large-scale deployment. This approach delivers significant cost advantages over traditional methods, making it possible to produce PSCs on a gigawatt (GW) scale for 1/10 the cost of an equivalent silicon production line.
