Dyenamo expands materials offer for perovskite-silicon tandem solar cells
In response to its customers’ needs, Sweden’s Dyenamo has added several new perovskite product lines and increased production of materials for the full range of perovskite solar cell designs.
Weekend Read: The fruitful search for other thin films
First Solar and its cadmium telluride (CdTe) technology dominate thin-film solar in the mainstream market. Valerie Thompson looks at the US-based business and the future of thin-film PV technology.
All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency
Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.
Additive allows all-perovskite tandems to hit 24.2% efficiency
Scientists led by China’s Nanjing University discovered that a chemical commonly used for bleaching in the textile industry can also serve as a performance-boosting additive to mixed lead/tin perovskite thin films. Using this additive, they were ultimately able to fabricate a two perovskite tandem cell measuring 1.05cm² that achieved 24.2% efficiency.
