Latest Patents

Among his latest inventions, Bell has developed several groundbreaking methods in solar cell technology. One notable patent is for a "Method of making a transparent and electrically conductive bond." This innovative approach allows solar cells with different bandgaps to be stacked, forming a multijunction photovoltaic converter with improved conversion efficiency. By mechanically stacking the cells instead of growing them simultaneously, this method provides the flexibility to select the most suitable materials for the cells. The stacking process is finalized using a glass sealing layer with moats that contain inter-cell contacts bonded to the solar cells.

Another significant patent is for a "Grooved solar cell for deployment at set angle." This design minimizes contact obscuration and series resistance by featuring a regular array of walls formed by grooves in a crystalline semiconductor substrate that is strategically exposed to incoming radiation. Metallic contacts are placed on the walls of the grooves that do not receive sunlight, and the solar cell is mounted at a predetermined angle to optimize energy capture. This innovative technique is further enhanced by using orientation-specific etches for groove formation.
