Title: Innovations by Peter Alex Shevchuk
Introduction
Peter Alex Shevchuk is an accomplished inventor based in Arvada, Colorado. He has made significant contributions to the field of photovoltaic technology, particularly in the development of methods for manufacturing copper indium gallium diselenide (CIGS) solar cells. With a total of two patents to his name, Shevchuk's work is paving the way for advancements in renewable energy.
Latest Patents
Shevchuk's latest patents focus on 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.
