By applying a perovskite cell just 500 nanometers thick onto a conventional silicon solar cell, the theoretical efficiency limit increases from 29.4 to 43.3 percent. <\/p>\n\n\n\n

To pave the way for the industrial implementation of this tandem technology, the Fraunhofer Institute for Solar Energy Systems ISE opened a new laboratory today. The \u201cPero-Si-SCALE\u201d offers an independent R&D infrastructure and is available to the German and European photovoltaic industry. In particular, solar cell and module manufacturers can use it to scale up new cell designs to large cell formats using industry-standard manufacturing processes, analyze them extensively, and integrate them into PV modules.<\/p>\n\n\n\n

\u201cPhotovoltaics is far from being \u2018fully researched,\u2019\u201d said Prof. Dr. Stefan Glunz, Head of the Photovoltaics Division at Fraunhofer ISE, at the opening. \u201cOn the contrary, there is still a great deal to be gained here, and tandem solar cells are the key to achieving even greater efficiency. This means more solar energy in a smaller area and with less material usage.\u201d<\/p>\n\n\n\n

The new Pero-Si-SCALE<\/a> builds on developments from the laboratory (Technology Readiness Level TRL1\u2013TRL4) and transfers the innovative cell designs to industrial cell formats\u2014up to a wafer size of 210 by 210 square millimeters\u2014using scalable, high-throughput manufacturing processes. In addition to the development of perovskite-silicon solar cells and modules, as well as technologies for their manufacturing, the Pero-Si-SCALE also offers a comprehensive characterization and analysis environment. <\/p>\n\n\n\n

\u201cThe new laboratory infrastructure builds on 20 years of experience in industry-oriented development of silicon photovoltaics at the Photovoltaic Technology Evaluation Center (PV-TEC),\u201d explained Priv.-Doz. Dr. Ralf Preu, Head of the Photovoltaics Division at Fraunhofer ISE. \u201cThe PV-TEC also ensures the supply of optimized silicon bottom cells to the Pero-Si-SCALE, as well as a close connection to current production processes.\u201d<\/p>\n\n\n\n

Fraunhofer ISE focuses on the so-called \u201chybrid route\u201d\u2014a combination of vacuum and wet chemical processes\u2014for the manufacturing process of perovskite-silicon tandem solar cells. Using this technology, the institute has already achieved peak efficiencies of over 33 percent on a laboratory scale. This process has the advantage that \u201cstandard,\u201d textured silicon solar cells from the industry can still be used. This allows for direct integration with today\u2019s solar cell standards and achieves a higher energy yield from the tandem modules. The successful combination of a wide variety of thin-film deposition technologies with wafer-based silicon technology is the challenge for efficient industrial implementation.<\/p>\n\n\n\n
