Chlorinated Cation Unlocks Durable Tin Perovskite Solar Cells in Open Air
4+ hour, 5+ min ago (489+ words) Tin halide perovskites have long been the tantalizing alternative to lead-based perovskites in next-generation solar cells. They offer a narrower bandgap that is ideal for harvesting more of the solar spectrum, and they replace toxic lead with an environmentally friendlier…...
Machine learning boosts first-principles study of perovskite photovoltaic

Airflow vs Dagster vs Prefect: 2026 Pricing Compared
4+ day, 10+ hour ago (797+ words) All three tools solve the same underlying problem: run a sequence of interdependent tasks on a schedule or trigger, retry the ones that fail, and give engineers visibility into what ran and when. Beyond that shared goal, the three projects…...
Perovskite Multijunction Solar Cell Research at the University of Sydney by Professor Anita Ho-Baillie
5+ day, 5+ hour ago (226+ words) Nanyang Technological University - NTU Singapore NTU MSE Seminar Hosted by Assistant Professor Leonard Ng Wei Tat Professor Anita Ho-Baillie is the John Hooke Chair of Nanoscience at the University of Sydney, a 2020 Australian Research Council Future Fellow, and was an…...
Understanding Apache Airflow 3.3: Key Improvements, Features Every Data Engineer Should Know, and Real-World Use Cases.
5+ day, 20+ hour ago (267+ words) 1. The Task and Asset State Stores With the Task State Store Airflow 3.3 utilizes tasks to save pieces of metadata that persist across retries. Instead of starting over from scratch, a subsequent attempt of the same task can fetch the metadata,…...
Enterprise Data Pipelines Are Only as Good as Their Backup Plan
5+ day, 20+ hour ago (283+ words) A data engineering lead at a regional insurance company once discovered, during an actual disaster recovery drill, that their nightly backup had been silently failing for eleven days. The pipeline itself was fine. The job that fed it, updated during…...
Scientists make lead-free perovskite solar cells that can weather the elements
6+ day, 15+ min ago (632+ words) There’s an old expression: you can’t see the forest for the trees. It feels particularly apt when talking about the transition to green energy. Electric cars may eliminate tailpipe emissions, but we still have to ask where their electricity comes…...
Japanese scientists improve performance for tin-halide perovskite solar cells
1+ week, 2+ day ago (204+ words) Scientists in Japan have developed a new approach that they claim can improve the durability of tin-based perovskite solar cells. Researchers at the Sophia University in Tokyo and the and the National Institute for Materials Science (NIMS) in Tsukuba, both…...
Chinese scientists build 27.39%-efficient inverted perovskite solar cell based on new molecular design
1+ week, 2+ day ago (237+ words) A research group in China has fabricated a perovskite solar cell using a new molecular design approach aimed at reducing defects in the perovskite film and increasing device efficiency and stability. The proposed molecular design approach is described as a…...
Tin perovskite cell longevity and efficiency improved by heteroatom additive
1+ week, 3+ day ago (261+ words) Researchers from the Sophia University (SU) and the National Institute for Materials Science (NIMS) in Japan have minimised tin-based pervoskite solar cell oxidisation, which affects the efficiency and longevity of the cells, progressing the technology toward commercial viability. 2-ABZ is…...
