Researchers in Germany are scaling up efforts to bring perovskite-silicon tandem solar cell technology into industrial scale production. The scientists say manufacturing cells of that kind is possible on widely-available six-inch silicon wafers and modular systems are being designed to do so at scale.
The French institute said the result has been certified by ISFH CalTeC, in Germany. The manufacturers claim they were able to increase cell performance by improving the plasma-enhanced chemical vapor deposition of amorphous silicon nanolayers and the conductive and anti-reflective transparent oxide layers.
Tempress systems, a subsidiary of U.S. based Amtech, has received a follow-on order for a multi-phase 1 GW project. The turnkey order is for an n-type bifacial manufacturing line, and includes high throughput PECVD and diffusion platforms.
The Swiss equipment company will provide its OCTOPUS II PECVD/PVD platform to King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.
The bookings for the last four months include PECVD orders and an n-type bifacial turnkey line for customers in Asia, and will ship in the next six to nine months.
