Abstract
In recent years, in order to cope with climate and energy issues for green transformation, many countries have successively laid out the solar photovoltaic industry, making the photovoltaic industry the fastest growing industry in the energy sector. Among them, perovskite tandem cells (TSCs) are an important development direction. The stacked cells composed of perovskite top cells (PSCs) and silicon-based heterojunction (HJT) cells currently achieve a maximum photovoltaic conversion efficiency (PCE) of 31.25% and have great potential for development. This paper reviews the research and development process of the perovskite/silicon-based HJT tandem battery, and analyzes the methods to improve its PCE and stability through the research on the structure of the top, bottom and transition layers of the perovskite/silicon-based HJT tandem battery, in order to provide useful information in the industrial development and application.
