Mixed halide wide-bandgap (WBG) perovskites, widely used as a top-cell absorber in tandem solar cells, exhibit severe photoinduced phase segregation. A feasible solution is to exploit pure-iodide WBG essentially increasing Cs content instead of Br achieve bandgap widening. However, the efficiency pure-iodine perovskite cells (PSCs) reported so far has been inferior that typical mixed PSCs due complex nucleation and transition processes, leading poor crystallization quality high density defect states perovskites. Here, by combining lead thiocyanate (Pb(SCN)2) oleylamine hydrochloride (OAmCl) with Cs0.3DMA0.2MA0.5PbI3 precursor, homogeneous distribution obtained, resulting enhanced reduction excess source defects. With this approach, film improved along fewer surface-bulk defects well beneficial surface electronic properties. As result, deliver 21.55%, an extremely fill factor 86.03%, superior photostability. The target fundamentally free segregation under continuous light for 12 h (AM 1.5 G illumination, xenon lamp, 1 sun).

Organic–inorganic hybrid perovskite solar cells (PSCs) have shown tremendous promise due to their excellent optoelectronic properties and cost-efficient fabrication. However, the efficiency of traditional lead halide PSCs is approaching Shockley–Queisser limit, prompting interest in tin-lead (Eg ≈ 1.25 eV) as a candidate for tandem configurations with potential surpass this limit. A key challenge lies optimizing hole transport layer (HTL), widely used PEDOT:PSS suffers from high acidity poor crystallinity, hindering device performance. In work, we formic acid modification enhance its conductivity, energy band alignment, crystallinity. Acid treatment promotes proton transfer, reducing insulating PSS chains improving phase separation, thereby facilitating efficient transport. Tin–lead films fabricated on acid-treated (Fa-PEDOT:PSS) exhibit improved larger grain size, reduced defect density. Devices incorporating Fa-PEDOT:PSS demonstrate enhanced photovoltaic performance, achieving power conversion (PCE) 21.87% hysteresis stability, retaining ∼90% initial after 1600 h an inert atmosphere. These findings highlight optimized HTL tin–lead PSCs, paving way high-efficiency, environmentally friendly technologies.
