Breaking the bottleneck of lead-free perovskite solar cells through dimensionality modulation

Abstract

Leveraging the dimensionality-modulation method to further boost the device efficiency and stability is the future roadmap for the development of lead-free perovskite solar cells.

Six metal cations in one double perovskite: exploring complexity of chloride elpasolites by high-throughput experimentation

“…6–10 Like their lead-based counterparts, many lead-free halide perovskites showed remarkable functional properties that can be harvested in LED technologies, X-ray detectors and photodetectors, photovoltaics (PV), photocatalysis, and other emerging applications. 6–17…”

“…This variability is further increased by orders of magnitude due to the unique structural tolerance of double perovskites allowing two or more cations to be alloyed on each of the metal positions, as well as two to three halide species to be combined in different proportions on the X site. 7,8,10,11,14,18…”

Ecofriendly Solution Processing of Perovskite Solar Cells Using Water

“…It is also important to tackle these issues in order to facilitate the industrial production and commercialization of PSCs. There have been extensive efforts to create perovskites that are free from lead, with a number of comprehensive review articles that delve deeply into this subject. − To maintain a coherent and focused discourse, we opt to limit our examination of lead-free perovskites within this Perspective, ensuring that we emphasize the advancements and potential of utilizing environmentally friendly solvent-based techniques for PSCs without deviating from broader discussions on lead alternatives.…”
