“…The spin-coating of the perovskite precursor solution involves an antisolvent treatment to facilitate the removal of the host solvent(s) molecules and as a consequence initiate the crystallization of the perovskite film. Several studies have reported the optimal conditions for this step, and it has been shown that antisolvent–solvent interactions, such as dipole–dipole interactions, modulate the dynamics of the process . The film morphology is affected by composition-dependent liquid-crystal dynamics and competing crystallization routes that occur during the crucial stages of film formation.…”

The development of emerging photovoltaic technology has promoted the innovation of building-integrated photovoltaics (BIPV) not only in lower cost and simpler processing technology but also in a variety of additional features such as flexibility and transparency. Semitransparent solar cells that allow partial transmission of visible light are excellent candidates for BIPVs owing to their unique properties and potential for integrated energy solutions. In this work, we present a straightforward and highly reproducible protocol for depositing extremely uniform and ultrathin perovskite layers. Our solution-processed perovskite solar cells, fabricated on flexible polymer substrates with large active area (1 cm2), achieved a noteworthy 5.7% power conversion efficiency (PCE) under standard conditions (AM 1.5G radiation, 100 mW cm–2) accompanied by an Average Visible Transmittance (AVT) of 21.5% for full device architecture with a 10 nm thick silver electrode. We present a simple yet elegant fabrication procedure for semitransparent perovskite solar cells without any additional antireflective layers. Furthermore, we fabricated working perovskite solar cells with the thinnest active layer of spin-coated MAPbI3 reported so far (10 nm) exhibiting 1.9% PCE and 41.1% AVT (62.9% AVT without electrode). These results hold great promise for the integration of perovskite-based semitransparent solar cells into real-world applications, advancing the landscape of renewable energy.

To optimize the process, a broad variety of solvents was examined, and it was found that the type of antisolvent used limits the window of operation for morphology and power conversion efficiency (PCE).…”

“…The type of antisolvent, the ratio between the precursor solvent and the antisolvent, and the antisolvent dripping time and speed are among key parameters to be considered for enhanced efficiency [37]. Even though the interaction between the solvent and antisolvent or between the precursor and antisolvent is governed by the nature of the antisolvent, an ideal antisolvent is required to be insoluble with both the host solvent and perovskite precursors but also miscible with host solvent [38]. When chlorobenzene was utilized in the fabrication of bismuth-based perovskite films, the result was a decrease in grain size and a modest improvement in surface coverage [39].…”

Cesium bismuth iodide perovskite material offers good stability toward ambient conditions and has potential optoelectronic characteristics. However, wide bandgap, absorber surface roughness, and poor surface coverage with pinholes are among the key impediments to its adoption as a photovoltaic absorber material. Herein, bandgap modification and the tailoring of surface morphology have been performed through molar ratio variation and antisolvent treatment, whereby type III antisolvent (toluene) based on Hansen space has been utilized. XRD and Raman spectroscopy analyses confirm the formation of a 0D/2D mixed dimensional structure with improved optoelectronic properties when the molar ratio of CsI/BiI3 was adjusted from 1.5:1 to 1:1.5. The absorption results and Tauc plot determination show that the fabricated film has a lower bandgap of 1.80 eV. TRPL analysis reveals that the film possesses a very low charge carrier lifetime of 0.94 ns, suggesting deep defects. Toluene improves the charge carrier lifetime to 1.89 ns. The average grain size also increases from 323.26 nm to 444.3 nm upon toluene addition. Additionally, the inclusion of toluene results in a modest improvement in PCE, from 0.23% to 0.33%.
