6 FAQs about [Solar Cell Crystal Orientation]

How can crystal orientation engineering improve the efficiency of perovskite solar cells?

Does crystal orientation affect power conversion efficiency of quasi-2D perovskite solar cells?

However, the power conversion efficiency (PCE) of quasi-2D perovskite solar cells decreases unfortunately with the increase of the 2D contents, which obviously depends on the orientation of the crystals. In this review, we first review the effect of the crystal orientation on the performance of quasi-2D PSCs.

What is the preferential orientation of crystal growth?

If the nucleation is initiated at the liquid–air interface, crystal growth has a clear preferential orientation compared to nucleation in the isotropic liquid or at the rough liquid–substrate interface (Figure 3B ).

How does crystal orientation affect optoelectronic properties?

The crystal orientation directly affects the optoelectronic properties. It is well-known that oriented crystals provide more efficient charge transport, giving rise to higher JSC and FF, but the impact of different crystal orientations on the internal electric field of PSCs is still unknown.

Why is molecular orientation important in organic solar cells?

The regulation principle of optimizing molecular orientation is revealed. The morphological characteristics of the active layer in organic solar cells (OSCs), encompassing phase separation structure, domain sizes, crystallinity and molecular orientation play a pivotal role in governing the photoelectric conversion processes.
