Technical Challenges and Perspectives for the Commercialization of Solution-Processable Solar Cells

As the new-generation photovoltaic technologies, organic solar cells (OSCs) and perovskite solar cells (PVSCs) offer significant advantages over Si- and CdTe-based solar cells, that is, facile low-temperature solution processability and excellent cost-performance ratios. At present, OSCs and PVSCs have achieved very high certified power conversion efficiencies of 17.5% and 25.5%, respectively, which have already approached the efficiencies needed for commercial applications. However, there are still several obstacles that need to be overcome before they can be deployed as new-generation of printable photovoltaic technologies. More efforts also need to be devoted to finding applicable methods for manufacturing highly efficient, large-area devices and improving their long-term operational stability. Thus, this article provides a comprehensive review on the current status and technical challenges for commercializing these two solution-processable solar cells.

Automated summary

Organic solar cells (OSCs) and perovskite solar cells (PVSCs) offer significant advantages over traditional solar cells, with high power conversion efficiencies approaching commercial application levels. However, challenges such as manufacturing and long-term stability still need to be addressed before widespread commercialization.
