Title: Innovations by Ajay Kumar Kalla in Photovoltaic Technology
Introduction
Ajay Kumar Kalla is a notable inventor based in Centennial, Colorado, recognized for his contributions to the field of photovoltaic technology. He holds two patents that focus on the manufacturing processes of copper indium gallium diselenide (CIGS) compound semiconductors. His work is pivotal in advancing the efficiency and effectiveness of solar energy solutions.
Latest Patents
Kalla's latest patents include a machine and process for sequential multi-sublayer deposition of copper indium gallium diselenide compound semiconductors. This innovative method involves the sequential deposition of CIGS compounds in multiple thin sublayers, which form a composite CIGS absorber layer. The process is designed to achieve a desirable thickness that exceeds that of each individual sublayer. Notably, the method is adaptable for roll-to-roll processing of CIGS photovoltaic cells. Additionally, it allows for the preparation of a CIGS absorber layer with a graded composition, enriched in copper at the base of the layer. Each CIGS sublayer is deposited through the co-evaporation of copper, indium, gallium, and selenium, which react in-situ to form CIGS.
