Latest Patents

One of Terao's latest patents is for a compact micro-concentrator for photovoltaic cells. This invention features a reflector array composed of multiple partial parabolic reflectors arranged in rows and columns. Each reflector directs radiation to a receiver or transmitter located at the focus of the reflector. In this compact arrangement, each photovoltaic cell is shielded from direct radiation by the adjacent reflector. The reflectors can be constructed as a single unit with reflective material or with surfaces coated in aluminum, silver, or other suitable materials. Additionally, a secondary reflector can be positioned at the focus to direct radiation to a more accessible location in the array.

Another significant patent is a method of fabricating a silicon solar cell. This method involves creating a back surface point contact silicon solar cell with p-doped and n-doped regions on the same side. The process includes forming a passivating layer with opened windows at the p-doped and n-doped regions, depositing and patterning a first metal layer of aluminum, and applying an insulator layer of inorganic material. The final steps ensure that the cell surface is well planarized for optimal conductibility, reducing voids and solder fatigue.
