Title: Innovations of Mohamed H Hilali in Photovoltaic Technology
Introduction
Mohamed H Hilali is an accomplished inventor based in San Ramon, CA (US). He has made significant contributions to the field of photovoltaic technology, particularly through his innovative patent that focuses on enhancing the efficiency of photovoltaic cells. His work is characterized by a commitment to advancing renewable energy solutions.
Latest Patents
Hilali holds a patent for the "Creation of low-relief texture for a photovoltaic cell." This novel method describes the creation of a low-relief texture on either the light-facing surface or the back surface of a photovoltaic cell. The textured surface achieves a peak-to-valley height and average peak-to-peak distance of less than about 1 micron, with specific examples indicating heights of about 0.5 microns or less. In a completed photovoltaic device, the average reflectance for light wavelengths between 375 and 1010 nm at the light-facing surface with this texture is 6 percent or less, with instances showing reflectance as low as 3.5 percent. The texture is produced by forming an optional oxide layer, lightly buffing the surface, and etching with a crystallographically selective etch. Remarkably, excellent texture can be achieved with etching times of twelve minutes or less, while minimizing silicon loss to about 0.3 mg/cm or less.
