Toward Maximizing Hole Selection with Self-Assembled Monolayers in Sn-Based Perovskite Solar Cells | ACS Energy Letters pubs.acs.org/doi/10.1021/...
Toward Maximizing Hole Selection with Self-Assembled Monolayers in Sn-Based Perovskite Solar Cells
Even though hole-selective self-assembled monolayers (SAMs) are a key player for light management and carrier management in Pb- and Sn–Pb based perovskite solar cells (PSCs), they are markedly underdeveloped for Sn PSCs. Herein, we offer multifaceted approaches as a roadmap to tackle this challenge. We systematically reviewed recent publications on Sn PSCs utilizing hole-selective SAMs to identify underexplored approaches and suboptimal photovoltaic performance. We then examined state-of-the-art PSCs based on Pb and Sn–Pb perovskites to induce their success to arise from multifaceted approaches on the substrate, SAM, perovskite, and their interfaces. Additionally, we emphasized the unique underlying properties of Sn PSCs that warrant careful consideration. Finally, we proposed feasible approaches to improve the SAM-based Sn PSCs, in light of light management and carrier management, by leveraging the unique properties of Sn perovskites alongside the multifaceted approaches proven effective in other PSCs.

These rounded QDs have polarized facets that steal energy from charge carriers, red-shifting photoluminescence!

Recipe for Flat Bands in Pyrochlore Materials: A Chemist’s Perspective
Materials in which atoms are arranged in a pyrochlore lattice have found renewed interest, as, at least theoretically, orbitals on that lattice can form flat bands. However, real materials often do not behave according to theoretical models, which is why there has been a dearth of pyrochlore materials exhibiting flat band physics. Here, we examine the conditions under which ideal “pyrochlore bands” can exist in real materials and how to have those close to the Fermi level. We find that the simple model used in the literature does not apply to the bands at the Fermi level in real pyrochlore materials. However, surprisingly, we find that certain oxide compounds that have oxygen orbitals inside the pyrochlore tetrahedra do exhibit near-ideal pyrochlore bands near the Fermi level. We explain this observation by a generalized tight-binding model, including the oxygen orbitals. We further classify all known pyrochlore materials based on their crystal structure, band structure, and chemical characteristics and propose materials to study in future experiments.
