“…Mixed-cation perovskites have been seen to offer good prospects for enhancing the stability of PSCs [31]. Despite numerous experimental reports concerning the mitigation of the degradation effects, there is still a lack of predictive approaches that can guide the synthesis process.…”

The feasibility of mixed-cation mixed-halogen perovskites of formula AxA’1−xPbXyX’zX”3−y−z is analyzed from the perspective of structural stability, opto-electronic properties and possible degradation mechanisms. Using density functional theory (DFT) calculations aided by machine-learning (ML) methods, the structurally stable compositions are further evaluated for the highest absorption and optimal stability. Here, the role of the halogen mixtures is demonstrated in tuning the contrasting trends of optical absorption and stability. Similarly, binary organic cation mixtures are found to significantly influence the degradation, while they have a lesser, but still visible effect on the opto-electronic properties. The combined framework of high-throughput calculations and ML techniques such as the linear regression methods, random forests and artificial neural networks offers the necessary grounds for an efficient exploration of multi-dimensional compositional spaces.

“…The molecular engineering of organic small molecules as ILs for the scale-up of PV technologies is currently a very active field of research, especially with regard to the development of HTLs for PSCs, which is one of the most crucial aspects of the whole technology. [193][194][195][196] In particular, the use of a new, low-cost, dopant-free HTL in mixed-ion solution-processed PSCs allowed to achieve the record PCE of 19.7%. [85] This result was obtained through an approach based on the integration among rational molecular design, device fabrication, and characterization, which shed light on the nanostructure and molecular aggregation of the HTL.…”

The development of efficient, reliable, and clean energy sources is one of the global priorities for enabling a sustainable transition toward a green society and economy. The third‐generation solar cells, such as organic solar cells (OSCs) and perovskite solar cells (PSCs), are among the most promising platforms for the generation of electrical power from sunlight for a wide range of applications. However, the widespread diffusion of emerging photovoltaics technologies is hampered by issues occurring in the translation of laboratory‐scale R&D efforts to real settings. Herein, starting from a thorough survey of latest research on OSC and PSC technologies, critical factors related to fabrication and operation of solar cells, especially in terms of materials properties/requirements and beyond metrics built on efficiency only, are analyzed. On this basis, OSCs and PSCs are compared in terms of their potential in real application scenarios, also highlighting their peculiarities in view of their future large‐scale utilization.

“…All rights reserved reported in the literature, spiro HTL is a great choice to obtain high efficiency up to 24%, 10 however, the stability of the device is still a big challenge mainly due to the presence of unstable dopants in the HTL and its organic nature. 38 To improve the stability of the spiro-based PSCs, additive engineering and double layer HTL could be effective solutions. 39,40 For example, Sunehira et.…”
