“…To further improve the PCE of perovskite-organic TSCs and optimize WBG perovskites with complementary absorption spectra of OSCs, it is also necessary to design NBG OSCs with extended near-infrared light absorption. [58] In the early stage, due to the restricted tunability of fullerene's energy levels, advancements in OSCs were hindered, reaching efficiency of approximately 11%. [59] The conventional fullerene acceptors exhibit inadequate light absorption and limited structural diversity, thereby impeding the fabrication of more efficient devices.…”

Perovskite‐organic tandem solar cells (TSCs) have emerged as a groundbreaking technology in the realm of photovoltaics, showcasing remarkable enhancements in efficiency and significant potential for practical applications. Perovskite‐organic TSCs also exhibit facile fabrication surpassing that of all‐perovskite or all‐organic TSCs, attributing to the advantageous utilization of orthogonal solvents enabling sequential solution process for each subcell. The perovskite‐organic TSCs capitalize on the complementary light absorption characteristics of perovskite and organic materials. There is a promising prospect of achieving further enhanced power conversion efficiencies by covering a broad range of the solar spectrum with optimized perovskite absorber, organic semiconductors as well as the interconnecting layer's optical and electrical properties. This review comprehensively analyzes the recent advancements in perovskite‐organic TSCs, highlighting the synergistic effects of combining perovskite with a low open‐circuit voltage deficit, organic materials with broader light absorption, and interconnecting layers with reduced optical and electrical loss. Meanwhile, the underlying device architecture design, regulation strategies, and key challenges facing the high performance of the perovskite‐organic TSCs are also discussed.

“…From the chemistry aspect, metal halide perovskites and their integration in solar cells, better known as perovskite solar cells (PSCs), have made a huge and very swift progress during the past decade, from its first solid-state emerging solar cell introduced in 2012 with PCE already over 10% [13] to the latest lab efficiency report of 26.0% for a single junction PSC and 33.7% for a perovskite/silicon TSC [14]. As organic/inorganic hybrids, perovskites have gained a key position in the solar cell industry due to their tunable optical properties, efficient light absorption coefficient, long carrier diffusion length, and low-cost fabrication methods rooted in their solution processibility, which is pushing PSCs' largescale production forward [15,16].…”

Metal halide perovskite nanowires (PrvNWs) have recently emerged as an interesting path for nanostructured solar cells. Here, we model the absorption of light in PrvNW arrays for varying diameter and length of the PrvNWs and period for the array by solving the Maxwell equations. For long enough bare PrvNW arrays, we find that the optimum diameter is fixed to that which places the absorption peak from the HE11 waveguide mode in the PrvNWs to the vicinity of the bandgap wavelength. In contrast, when we include a transparent conductive oxide (TCO) top contact layer, the optimum diameter shifts to a larger value by 100 nm. The origin of this shift is traced to a reduced reflection at the interface between the TCO layer and the PrvNW array when the PrvNW’s diameter is larger. Overall, we find that 1500 nm long PrvNWs can reach 90% of the broadband absorption potential, making this system of high interest for photovoltaics.

“…[ 13–16 ] However, the highest PCE of POTSCs reported up to now is 24.0%, which is inferior to other types of PTSCs, mainly resulting from the severe energy loss of wide‐bandgap (Eg) perovskite sub cells with I/Br ratio close to 0.5:0.5 and the lack of near infrared (NIR) acceptors with superior carrier transporting properties. [ 15,17 ]…”

Perovskite/organic tandem solar cells (POTSCs) are gaining attention due to their easy fabrication, potential to surpass the S‐Q limit, and superior flexibility. However, the low power conversion efficiencies (PCEs) of wide bandgap (Eg) perovskite solar cells (PVSCs) have hindered their development. This work presents a novel and effective mixed‐cation passivation strategy (CE) to passivate various types of traps in wide‐Eg perovskite. The complementary effect of 4‐trifluoro phenethylammonium (CF3‐PEA+, denoted as CA+) and ethylenediammonium (EDA2+, denoted as EA2+) reduces both electron/hole defect densities and non‐radiative recombination rate, resulting in a record open‐circuit voltage (Voc) of wide‐Eg PVSCs (1.35 V) and a high fill factor (FF) of 83.29%. These improvements lead to a record PCE of 24.47% when applied to fabricated POTSCs, the highest PCE to date. Furthermore, unencapsulated POTSCs exhibit excellent photo and thermal stability, retaining over 90% of their initial PCE after maximum power point (MPP) tracking or exposure to 60°C for 500 hours. These findings imply that the synergic effect of surface passivators is a promising strategy to achieve high‐efficiency and stable wide‐Eg PVSCs and corresponding POTSCs.This article is protected by copyright.
