ACS Energy Letters, Год журнала: 2024, Номер 9(1), С. 308 - 322

Опубликована: Янв. 2, 2024

Metal halide perovskite quantum dots (PQDs) not only share the common feature of confinement effect found in traditional but also exhibit favorable characteristics materials, including defect tolerance and long exciton lifetime. Thanks to these merits, within ten years research development, dot-based solar cells (PQDSCs) have attained a certified power conversion efficiency (PCE) 18.1%, which is, however, still far below those market-dominant silicon bulk thin-film counterparts. In this Focus Review, we analyze state-of-the-art development PQDSCs propose innovative strategies surface management, compositional control, band-alignment design. The potential utilizing PQDs' multiple generation is further discussed with good hope improving PCE beyond Shockley–Queisser limit.

Abstract Over the last decade, perovskite solar cells (PSCs) have drawn extensive attention owing to their high power conversion efficiency (single junction: 26.1%, perovskite/silicon tandem: 33.9%) and low fabrication cost. However, short lifespan of PSCs with initial still blocks practical applications. This operational instability may originate from intrinsic extrinsic degradation materials or devices. Although lifetime has been prolonged through component, crystal, defect, interface, encapsulation engineering, so on, systematic analysis failure regularity for perspective devices against multiple operating stressors is indispensable. In this review, we start elaboration predominant pathways mechanism under working stressors. Then strategies improving long‐term durability respect fundamental materials, interface designs, device summarized. Meanwhile, key results discussed understand limitation assessing stability, potential applications in indoor photovoltaics wearable electronics are demonstrated. Finally, promising proposals, encompassing material processing, film formation, strengthening, structure designing, encapsulation, provided improve stability promote commercialization. image

Abstract Perovskite quantum dots (PQDs) have emerged as competitive optoelectronic materials for photovoltaic applications due to their ideal bandgap energy, high defect tolerance, and solution processability. However, the highly dynamic surface imperfect cubic structure of PQDs generally result in unfavorable charge‐carrier transport within PQD solids serious nonradiative recombination. Herein, a orientated solid is demonstrated using precursor engineering accompanied by chemical stripping treatment (CST). A combination systematic experimental studies theoretical calculations conducted fundamentally understand resurfacing CST approach. The results reveal that ordered can orientation solids, significantly promoting solids. Meanwhile, cubic‐structured with an iodine‐rich dramatically decreases trap states, thereby substantially diminishing trap‐assisted Consequently, inorganic solar cell delivers power conversion efficiency up 16.25%. This work provides feasible avenue construct improved photophysical properties high‐performance devices.
