Nuclei engineering for even halide distribution in stable perovskite

Film growth generally starts from nuclei, which play an important role in determining final film properties. In the context of phase evolution, the pure FAPbI 3 precursor (where FA is formamidinium) prefers to nucleate as the hexagonal (2H, δ) phase, and high-temperature annealing is needed to obtain the desired cubic phase (3C, α) (20, 21).

Can in situ monitoring of perovskite crystallization improve the performance of photovoltaic devices?

Here we use in situ monitoring of the perovskite crystallization process to report an oriented nucleation mechanism that can help to avoid the presence of undesirable phases and improve the performance of photovoltaic devices in different film-processing scenarios.

Does Formamidinum lead iodide perovskite have Photoinduced phase segregation and humidity instability?

Formamidinum lead iodide perovskite solar cells commonly suffer from photoinduced phase segregation and humidity instability. Here, the authors design a multifunctional fluorinated additive to promote orientated crystallization of α-phase, and achieve maximum efficiency of 24.1% and T95 over 1000 h.

What are the photovoltaic parameters of perovskite modules?

Box plots showing the distribution of the a, PCE, b, FF, c, Voc, d, Isc for the control and the PAd-based perovskite modules with an aperture area of 30.86 cm 2. Centre line, median; box limits, 25 th and 75 th percentiles; curve, normal distribution curve; whiskers, outliers.

How efficient are Formamidinum lead iodide perovskite solar cells?

The unencapsulated devices achieve 24.10% efficiency and maintain >95% of the initial efficiency for 1000 h under continuous sunlight soaking and for 2000 h at air ambient of ~50% humid, respectively. Formamidinum lead iodide perovskite solar cells commonly suffer from photoinduced phase segregation and humidity instability.

Does fluorinated additive stabilize -phase of perovskite?

Therefore, we design a multifunctional fluorinated additive, which restrains the complicated intermediate phases and promotes orientated crystallization of α-phase of perovskite. Furthermore, the additives in-situ polymerize during the perovskite film formation and form a hydrogen-bonded network to stabilize α-phase.
