Indian scientists build 29.14%-efficient tandem solar cell with inverted top perovskite device
The researchers said they optimized the low-bandgap inverted perovskite cells through a passivating aluminum oxide (Al2O3) interlayer deposited via atomic layer deposition (ALD), which significantly helped improve device efficiency.
Perovksite-TOPCon tandem solar cell based on self-assembled monolayer achieves 31.1% efficiency
Researchers in China have fabricated a perovskite-TOPCon solar cell with a top perovskite device utilising a self-assembled monolayer aimed to improved cell stability. The tandem cell achieved a high fill factor and a certified efficiency of 30.9%.
Sekisui, TNO exploring perovskite solar PV collaboration
Japan’s Sekisui Solar Film and the Netherlands’ TNO have signed a letter of intent to explore collaborations related to flexible perovskite solar PV. Talks will be initiated on a potential perovskite module factory in Brabant and the exchange of relevant information.
Perovskite tandem provider integrates with existing solar manufacturing lines
While many perovskite developers pursue a 2-terminal format, which poses design and production constraints, Caelux uses a 4-terminal approach that bypasses technical challenges.
Scientists unveil durable perovskite PV modules with carbon nanotube electrode
Japanese researchers have engineered a 100 cm² perovskite solar cell module featuring a robust single-walled carbon nanotube (CNT) electrode to improve durability and enable dual-sided light absorption.
Indian scientists design 31.16%-efficient 2D-3D perovskite solar cell
Scientists in India have simulated a novel perovskite solar cell that combinies a Dion-Jacobson 2D layer with a 3D halide perovskite. The design showed improved stability compared to reference cells without the DJ-2D layer.
Chinese researchers build 4T perovskite-CIGS tandem solar cell with 29.36% efficiency
Scientists in China built a four-terminal perovskite-CIGS tandem solar cell based on a top semi-transparent perovskite device with an efficiency of 21.26% and a high bifaciality factor of 92.2%. They used a solvent-annealing strategy to produce a perovskite film with full coverage, larger grains, superior crystallinity and free of detectable lead iodide impurity.
Chinese startup unveils flexible perovskite photovoltaic modules with 15.6% efficiency
Mellow Energy claims its ML-Flex panel is currently the world’s largest flexible perovskite solar module. Available in five versions with power output ranging from 260 W to 300 W, the module measures 1,200 mm x 1,600 mm and weighs only 2.04 kg.
U.S.-made perovskite-silicon tandem solar modules could be produced at around $0.35/W
Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.
Field testing shows perovskite solar modules can retain 78% of their initial efficiency after one year
Researchers from Belgium and the University of Cyprus have completed outdoor stability tests of perovskite solar mini-modules providing two-years of data on stability performance. The tests showed that the modules’ performance loss rates during the burn-in period of perovskites ranged between 7% and 8% per month.
