The role of grain growth in controlling the crystal orientation of Sb₂S₃ films for efficient solar cells

Abstract

The orientation of antimony sulfide (Sb2S3) significantly affects the performance of the Sb2S3 thin film solar cells owing to its intrinsic quasi one-dimensional crystal structure. Producing Sb2S3 film with [hk1]...

Negative-pressure sulfurization of antimony sulfide thin films for generating a record open-circuit voltage of 805 mV in solar cell applications

“…This improvement led to an increased V OC of the Sb 2 S 3 -S-TF device. 43 Subsequently, electrochemical impedance spectroscopy (EIS) was used to investigate the effect of the sulfurization treatment on the internal charge transfer process of the device. The Nyquist plots and the fitted equivalent electronic circuit diagram of the solar cells are illustrated in Fig.…”

“…In previously reported studies, the as-prepared lms were generally annealed on a hot plate in a glove box lled with nitrogen (N 2 ) to improve their crystallinity. 31,[40][41][42][43][44] Here, we developed a new annealing method that introduced sulfur vapor into the annealing environment of the prefabricated lms, with the temperature ramping up slowly. Pressure played a signicant role in the sulfurization effect in this process.…”

A comprehensive insight into deep-level defect engineering in antimony chalcogenide solar cells

“…Wu et al 81 investigated the structure–property–performance relationship in Sb 2 S 3 thin-film solar cells via the in-depth characterization of the crystal orientation, carrier transport and device performance. The study revealed that by merely controlling the post-annealing process, the grain growth, orientation and defect physics can be regulated.…”

“…It was concluded that the sensitive manipulation of the reaction kinetics via the additive-assisted CBD technique offers an effective route for the fabrication of high-quality Sb 2 Se 3 films and high-PCE (10.57%) solar cells.

Theoretical studies on surface kinetics and growth properties of Sb2Se3 and Sb2S3

“…Secondly, it was found that the growth orientation plays an important role in determining the PCEs of these two crystals, mostly due to their quasi one-dimensional (Q1D) structures. 15,21,[28][29][30][31][32] There is still a lack of basic investigation on the adsorption and diffusion properties of the intrinsic atoms on surfaces, which is the rst step in understanding the defect properties and controlling the growth orientation.…”
