Are perovskite and charge-transporting layers limiting the durability of solar cells?

Nature Energy (2024) Cite this article The heterointerfaces between perovskite and charge-transporting layers pose a major limitation to the durability of perovskite solar cells (PSCs), largely due to complex and conflicting chemical and mechanical interactions.

Do heterostructures respond to full solar light for photocatalytic applications?

Breakthrough heterostructures that use the full range of solar light have recently been constructed, but comprehensive accounts of heterostructures that respond to full solar light for photocatalytic applications remain scarce.

Can heterostructures harvest full solar light?

Thus, these well-designed heterostructures can harvest full solar light because the selected semiconductors or noble metals absorb in different regions of the solar spectrum. For instance, we previously prepared NaYF 4:Yb 3+,Tm 3+ /SnO 2 /Ag heterostructures as UV–Vis-NIR-responsive photocatalysts using a step-by-step coating method (Fig. 5a–c).

How chiral-structured interlayers are used in encapsulated solar cells?

They inserted chiral-structured interlayers based on R -/ S -methylbenzyl-ammonium between the perovskite absorber and electron transport layer to create a strong, elastic heterointerface. The encapsulated solar cells retained 92% of their power conversion efficiency of about 26% after 200 cycles between −40° and 85°C for 1200 hours. —Phil Szuromi

Which heterostructure is prepared for degradation of organic pollution under full solar light?

For example, a CQDs/Ag/Ag 2 O heterostructure was prepared for the degradation of organic pollution under full solar light (Fig. 5h) . CQDs/Ag/Ag 2 O showed continuous strong absorption in the 250–2500 nm range, with good photocatalytic properties when irradiated with NIR light (Fig. 5i).

Can natural chiral structures improve the mechanical reliability of perovskite solar cells?

The strength of natural chiral structures has been mimicked to improve the mechanical reliability of perovskite solar cells. Duan et al. addressed the problem of the relatively low mechanical reliability of interfaces between layers that have different thermal expansion properties.
