Chinese scholars have made progress in the field of organic solar cells

In recent years, solution-printable organic solar cells have shown great application prospects in portable energy, building photovoltaic integration, etc.
Breaking through the limitations of crystalline silicon cells in application scenarios, it has become a disruptive photovoltaic technology
.

In response to the above problems, the research team developed a unique active layer guest-assisted assembly strategy, which achieved the preparation of high-quality active layers by using environmentally friendly high-boiling solvents and printing methods; The components are effectively regulated in terms of compatibility, solubility, macro- and micro-scale assembly behavior, etc.
, avoiding post-treatment processes such as thermal annealing, and simplifying the device fabrication process
.

This work is application-oriented and solves multiple bottleneck problems in the preparation of large-area modules of solution-printable organic solar cells, which will accelerate the industrialization of organic solar cells
