Novel quantitative valuation of hybrid perovskite solar cells.

As an emerging photovoltaic technology, hybrid perovskite solar cells (PSCs) have achieved excellent performance through rapid development in recent years. High power conversion efficiency (PCE) and excellent stability further promote the commercialization of PSCs. To date, the perovskite light-harvesting active materials are diversified and the device fabrication process is also various. Considered the fabrication costs and steps of PSCs based on different active materials, the quantitative valuation of different hybrid PSCs with PCE above 20% is implemented using data envelopment analysis (DEA) for the first time. This valuation mainly focuses on the inputs (cost and fabrication steps) and outputs (PCE and stability). No weights are needed during the whole analytical process. This ensures the convenience and ease of operation of the analysis, promoting the universality of this method. The results show a detailed analysis of different PSCs from an economic perspective and develop a new way to evaluate PSCs. Meanwhile, the results and this novel valuation method will provide promising guidance for the commercialization of PSCs.
