Perovskite solar technology is on the cusp of revolutionizing the global solar industry, according to a recent report by Rethink Energy. The report anticipates that gigawatt-scale manufacturing of perovskite solar cells will begin in 2028, with the first commercial products hitting the market as early as 2025. Perovskites are expected to outperform traditional silicon-based solar technologies by offering higher efficiencies and lower production costs, which will allow them to capture a substantial share of the global market over the next two decades.
The adoption of perovskite technology is being driven by its ability to significantly boost solar power output through tandem designs that combine perovskites with silicon. Current silicon-only modules have a theoretical efficiency limit of 29.4%, whereas tandem modules incorporating perovskites are projected to achieve efficiencies as high as 43% by 2040. This marked increase in efficiency will result in a considerable reduction in the cost of electricity generated from solar power, further establishing solar energy as a leading, cost-effective alternative to fossil fuels. Furthermore, perovskite tandem modules will reduce the cost per kilowatt by slashing many cost elements, from the modules themselves to installation labor, providing up to 25% more power from the same occupied area.
Beyond just reducing costs, the report highlights the transformative potential of perovskite technology in new and diverse commercial applications. One of the most promising applications is in building-integrated photovoltaics (BIPV), which could become especially prevalent in densely populated regions like Japan and Singapore. The unique lightweight and flexible properties of perovskite thin-film solar cells make them ideal for a variety of new uses, such as solar facades, translucent windows, and non-load-bearing rooftops. This will open new market segments for residential, commercial, and industrial solar installations, greatly expanding the reach and utility of solar technology.
In addition to efficiency and versatility, perovskites offer significant advantages in terms of sustainability and localization. The report notes that perovskite production is less resource-intensive compared to traditional silicon-based photovoltaics, requiring lower energy and capital investment. This positions perovskites as a key technology for solar manufacturing reshoring strategies, particularly in regions like the U.S. and Europe that are keen to reduce dependence on Asian supply chains. With fewer raw material constraints and simpler manufacturing processes, perovskites could become a crucial element in achieving energy independence and meeting ambitious renewable energy targets.
As the perovskite revolution gains momentum, it is expected to become the dominant force in solar power, pushing solar to become the majority contributor to new global energy capacity additions in the coming decades. The report from Rethink Energy suggests that the rise of perovskites could see solar power evolve from being a significant component of new energy installations to becoming the majority source of global electricity generation, reshaping the energy landscape for a more sustainable future.
