Abstract
This review surveys recent advances in employing photoluminescence quantum yield (PLQY) as a quantitative probe in perovskite solar cells (PSCs), highlighting its unique ability to diagnose interfacial nonradiative recombination, reconstruct quasi-Fermi-level splitting (QFLS), and anticipate efficiency limits. After presenting the theoretical framework that converts PLQY into QFLS so that it can be directly benchmarked against the device open-circuit voltage (), we clarify the complementarity between PLQY and conventional time-resolved photoluminescence. Representative case studies then illustrate how PLQY pinpoints recombination losses at the perovskite/electron-transport-layer and perovskite/hole-transport-layer interfaces and how targeted passivation strategies simultaneously enhance PLQY, QFLS, and overall device efficiency. The review also discusses how illumination intensity, excitation wavelength, temperature, and humidity influence PLQY measurements and argues that coupling high-throughput, in situ PLQY mapping with machine-learning algorithms promises to accelerate the discovery of highly efficient, lead-free, and stable perovskite materials and devices.

期刊介绍:
Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
