6 Conclusion
In conclusion, we elaborated the characterization method and regulation
strategy for regulating the crystallization kinetics and revealed the
underlying mechanism. First, we introduce the characterization methods,
including UV-vis absorption spectroscopy, PL, GIWAXS and GISAXS.
Subsequently, we introduced the regulation method of film-forming
process and post-annealing process and the mechanism of influence on
morphology, including film-forming method, solvent, temperature,
additive, TA and SVA. Through this review, we hope to deepen our
understanding of the effects of crystallization dynamics on the
morphology, which may guide to achieve higher device performance.
Since the appearance of OSCs, they have attracted extensive attention.
In order to promote the industrialization of OSCs, efforts can be made
from the following aspects: (1) Better materials, including electrode
materials, active layer materials and interface layer materials,
especially environmentally friendly materials should be designed; (2) A
deeper understanding of the relationship between fabricating
conditions-morphology-device performance; (3) development of the
characterization methods; (4) Meet the requirements of practical
applications such as stability and large-area solution fabrication of
devices.
