Scientists from Nanyang Technological University (NTU) in Singapore have created perovskite solar cells that are roughly 50 times slimmer than standard models, as detailed in a paper published in ACS Energy Letters. These devices, produced via a vacuum-based thermal evaporation technique, can be semi-transparent and produce electricity even under diffuse lighting, positioning them as viable candidates for incorporation into building windows and facades.
Professor Annalisa Bruno of NTU’s School of Physical and Mathematical Sciences and School of Materials Science and Engineering noted that buildings are responsible for about 40% of global energy consumption, making it increasingly urgent to develop technologies that discreetly turn building exteriors into energy-producing assets. She highlighted that their perovskite cells offer clear benefits, as they can be made through straightforward methods at relatively low temperatures, can be adjusted to capture specific light wavelengths while staying clear, and could be expanded for use on large surfaces, thereby lowering their carbon footprint.
Unlike traditional silicon solar cells, these perovskite devices can generate power under indirect or diffuse light. Bruno pointed out that this trait makes them especially fitting for Singapore’s urban landscape, where vertical surfaces and frequent cloud cover restrict direct sunlight exposure. Initial projections indicate that deploying this technology on a glass-facade building could yield hundreds of megawatt-hours annually, though the underlying assumptions and independent verification have not yet been made public.
The cells were manufactured using an industry-compatible thermal evaporation process, where materials are heated in a vacuum chamber until they vaporize and settle as thin layers on a substrate. Their semi-transparency and neutral color support integration into architectural glass uses. This method also sidesteps toxic solvents and minimizes flaws in the cells, boosting energy conversion efficiency. By tweaking deposition settings, the team managed the thickness of the perovskite layer and created both opaque and semi-transparent versions.
The researchers assert this marks the first instance of ultra-thin perovskite solar cells made solely through vacuum-based methods, a breakthrough that could facilitate scalable industrial production. With this approach, they produced perovskite absorber layers as thin as 10 nanometers while preserving functional performance. For opaque devices, conversion efficiencies reached 7% for 10 nm layers, 11% for 30 nm layers, and 12% for 60 nm layers. A semi-transparent cell with a 60 nm layer transmitted about 41% of visible light and achieved a conversion efficiency of 7.6%. The team did not disclose accelerated stability data or performance on large-area surfaces exceeding a few square centimeters.
Lead author Luke White explained that by precisely managing thermal evaporation, the transparency of the solar cells can be adjusted, unlocking new possibilities for sustainable architecture, such as tinted windows that generate electricity. A patent for the ultra-thin perovskite film structure has been submitted through NTUitive, NTU’s innovation arm. The researchers are currently collaborating with industry partners to validate and standardize the thermal evaporation process, as well as to enhance long-term stability, durability, and scalability ahead of potential commercialization.
