Abstract

fetched live from OpenAlex

Perovskite quantum dots (PQDs) have revolutionized the field of perovskite solar cells in recent years. Using PQDs improves the operational stability of these devices, which is one of their main drawbacks for applications. This factor has motivated an intense search for new advances, from a fundamental aspect to improved performance in devices. Therefore, the developments obtained for PQD solar cells are discussed, presenting the challenges already overcome and the upcoming tendencies for research. Thus, the fundamental aspects of halide perovskite structures are first introduced. The advantages of their preparation as quantum dots are presented as well. The advances for post‐treatments (purification, passivation, and ligand exchange) are then discussed. Next, an in‐depth discussion of the PQD solar cell architectures is made, highlighting both the obsolete configurations and upcoming tendencies. A more specific view of the PQD compositions is then made, including lead‐free compositions and strategies for ionic substitution. Links of the photovoltaic performance are constructed with the devices’ architecture, post‐treatments, and perovskite composition, providing a wide‐ranging overview of these parameters for the devices’ efficiencies. Finally, the authors’ point of view about the future of PQD solar cell technology is presented, showing the main drawbacks, advantages, and opportunities for research.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
