Innovation updates for organic and perovskites solar cells

Abstract

The innovation updates of organic photovoltaics (OPVs) and perovskite solar cells (Perovskites) patents is reviewed and analyzed in an international context. It is important to have an overview of solar cell patents distribution in recent years. There are four major patents authorities that relevant to organic and perovskite solar cells. The European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the Japanese Patent Office (JPO), and the World Intellectual Property Organization (WIPO) become the main tools for emerging solar cells analysis. In total, 5027 patents related to organic solar cell and 1764 patents related to perovskite solar cell were analyzed and then sorted in thematic subcategories. The analysis shows that inventors make highest impact in solar cells manufacturing areas and highlights the last years leaps in the field.
