Nines PV presents the ADE© technology: a unique, low cost, chemical DRY ETCHING of silicon production technology for the PV solar cell manufacturing industry. ADE is a novel, proprietary technology patented by NINES PV. Unlike RIE (Reactive Ion Etching), ADE does not require any high cost vacuum or plasma modules, and is purely a chemical etch process (no ions). It can scale to multi-GW levels, resulting in very low cost of ownership. It is currently the only viable industrial dry etching process available for the photovoltaic market.

Our single side etching process enables advanced cell architectures (TOPCON, HTJ, PERL, PEROVSKYTE...), through for exemple the removing of parasitic poly-silicon and edge isolation of TOPCON cells.    

Our advanced texturing process enables manufacturers to fully leverage the cost savings of diamond-wire cut multicristallyne wafers and novel kerfless wafer technologies, but also provides a roadmap for high efficiency PERC cells, enabling a path toward lower front surface reflectance and lower ligth angle dependance.

ADE allows manufacturers to start moving away from the traditionnal wet etching methods that have a large environmental and tool footprint. Our dry etch tools provide superior efficiencies, etch rate and tighter process control in a very small package.

Our silicon etching process is suitable for ANY type of Si WAFER or layers, using the same chemistry, without the use of any global warming gases, nor any water ! This is a FUTURE-PROOF solution... Thinking about your technology roadmap ? ADE allows to switch to any type of silicon wafer and provide a range of advanced processes  including textures (lower reflectivity / higher current) down to nano-textures and black silicon levels, as well as a very selective single side etching and edge isolation, opening a whole new range of possibilities. Also compatible with thin wafers, as low as 100um.
