Cross-linking strategy for solar cells

Are cross-linking strategies effective in achieving efficient and stable PSCs?

Finally, future perspectives and directions for cross-linking strategies are provided, which are expected to gather further research momentum in exploiting more efficient and durable cross-linking approaches to realize efficient, highly stable PSCs.

Why is in situ cross-linking important?

However, the instability of PSCs severely impedes their commercialization. Recently, in situ cross-linking strategy has been proposed to mitigate stability issues of PSCs, enabling highly efficient and stable PSCs. Here, the critical factors that lead to the degradation of PSCs are first outlined.

Does in situ cross-linking strategy exist in PSCs and other optoelectronic devices?

Finally, the current challenges and further development trends of in situ cross-linking strategy in PSCs and extension to other optoelectronic devices are prospected. The authors declare no conflict of interest.

Why are cross-linkable organic molecules important?

Recently, the cross-linking strategies involving cross-linkable organic molecules have come to the fore due to their great potential in synchronously enhancing the intrinsic, processing, thermal, and mechanical stabilities of perovskites.

How to improve the stability of solar cell devices?

Defective grain boundaries of polycrystalline perovskite films are one of the major causes of the instability of the solar cell devices. Here Han et al. choose a polymer with proper molecular structure to crosslink the perovskite grains to greatly improve the device stability.

Does in situ cross-linking polymerization improve crystal growth of perovskite films?

Comparatively speaking, in situ cross-linking polymerization shows more obvious superiority in the nucleation and crystal growth of perovskite films. However, no literature systematically reports the research progress and mechanism of the in situ polymerization reaction.
