Title: Cary Allen: Innovator in Photovoltaic Technology

Introduction

Cary Allen is a notable inventor based in Manchester, GB, recognized for his contributions to the field of photovoltaic technology. With a total of 3 patents, he has made significant advancements in the preparation and application of copper indium gallium diselenide (CIGS) nanoparticles.

Latest Patents

One of Cary Allen's latest patents is focused on the preparation of copper-rich copper indium (gallium) diselenide/disulfide nanoparticles. This method utilizes a copper-rich stoichiometry, allowing the nanoparticles to be capped with organo-chalcogen ligands, making them processable in organic solvents. These nanoparticles can be deposited on a substrate and thermally processed in a chalcogen-rich atmosphere, facilitating the conversion of excess copper to copper selenide or copper sulfide. This process promotes liquid phase sintering and the growth of large grains, which are essential for fabricating CIGS-based photovoltaic devices.

Another significant patent involves the development of an inorganic salt-nanoparticle ink for thin film photovoltaic devices. This composition includes ternary, quaternary, or quinary chalcogenide nanoparticles and one or more inorganic salts dissolved in a solvent to form an ink. The ink can be deposited on a substrate using conventional coating techniques and then annealed to create a crystalline layer. The inclusion of inorganic salts allows for tuning the stoichiometry of the CIGS precursor ink, doping the CIGS layer with additives, and improving the coating properties of the ink.
