Single-crystal perovskite solar cell beats 21% efficiency

Single-crystal perovskite solar cell efficiency has exceeded 21% at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, which is working on methylammonium lead-triiodide perovskites. The cell is part of a project to harness single-crystal growth as a way of avoiding the defects and restricted charge-carrier diffusion length associated with the polycrystalline thin-films ...

Lenovo takes No.1 PC vendor slot

Q2 PC shipments grew 4.7% y-o-y to 64.9 million units, reports IDC, as Lenovo became the No.1 vendor. Improved supply of Intel CPUs helped boost the figure while some companies shipped early to avoid possible future tariffs. Another boost came from the January 2020 end-of-service date for Windows. The US saw high single-digit growth, Canada ...
