Inverted perovskite solar cell based on ionic salt achieves 26% efficiency
An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and performance. Test results showed a 26% power conversion efficiency with 2% degradation after 2,100 hours of 1-sun operation at 65 C.
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.
Titanium makes perovskite solar cells more durable
After finding a way to make spiro-OMeTAD, a popular perovskite solar cell hole transport layer, less prone to heat-induced crystallization, researchers at Georgia Institute of Technology are now seeking partners to scale the technology for large-area PV cells.
Tandem PV moves toward perovskite manufacturing with $50 million funding announcement
With a perovskite layer 200 times thinner than silicon and requiring just 10% of the energy needed to produce conventional panels, Tandem PV reports it will be able to reduce energy use during manufacturing.
Water-based recycling of perovskite solar cells
An international team has developed a new technique to recycle perovskite solar cells (PSC) made on glass substrates using a water-based solution. Tests showed that the recycled cells were as efficient and stable as the original devices.
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%.
Perovskite solar beach umbrella and electric cooler
Anker introduced an off-grid solar perovskite umbrella and a cooler with battery energy storage at CES 2025 in Las Vegas, Nevada.
In case you missed it: Five big solar stories in the news this week
pv magazine USA spotlights news of the past week including market trends, project updates, policy changes and more.
Thin-film tandem solar in the U.S.
Tandem solar-cell technology featuring silicon has been widely researched but materials such as perovskites, paired with established thin-film solar or with other perovskite cells, are pointing to a new development path.
Oxford PV starts commercial distribution of perovskite solar modules
Oxford PV is delivering its first commercial perovskite solar modules to U.S. customers. The 72-cell solar modules have an efficiency of 24.5% and, according to the company, can generate up to 20% more energy than conventional silicon modules.
