Latest Patents

Ora Eli's latest patents include a method for producing photovoltaic devices isolated by porous silicon. This method utilizes a minimally modified standard process flow to create lateral P-I-N light-sensitive diodes on silicon islands. These islands are isolated laterally by trenches and from an underlying support substrate by porous silicon regions. The process involves forming P+ and N+ doped regions in a P− epitaxial layer, etching trenches through the epitaxial layer into a P+ substrate, and forming a protective layer on the trench walls. The resulting photovoltaic devices can be used to create low-cost embedded photovoltaic arrays on CMOS IC devices or can be separated from the P+ substrate to produce high-voltage solar arrays for solar energy sources.

Another notable patent is for a photovoltaic device formed on porous silicon isolation. This device features lateral P-I-N light-sensitive diodes on a silicon island, which is surrounded by trenches that provide lateral isolation. The island is separated from the substrate by a porous silicon region, which is grown under the island to isolate the lower portions of the device from the highly doped substrate. The trenches extend through the P− epitaxial material into the P+ substrate, facilitating self-limiting porous silicon formation and suppressing electron-hole recombination. The incorporation of black silicon on the trench walls enhances light capture, making these devices suitable for low-cost embedded photovoltaic arrays or high-voltage solar arrays.
