TL;DR: The thickness of the protective hafnium oxynitride layer at the surface of a silicon solar cell is reduced to just eight angstroms, using electric-field-effect passivation to enable the efficient energy transfer of the triplet excitons formed in the tetracene.
Solution-Processed Organic and Halide Perovskite Transistors on Hydrophobic Surfaces

TL;DR: The analysis of the density of trapping states at the semiconductor-dielectric interface suggests that the increase in the trap density as a result of the chemical treatment is minimal, and the devices exhibit good charge carrier mobilities, near-zero threshold voltages, and low electrical hysteresis.

TL;DR: In this paper, the orbital and transition energies of over 360 possible coronene derivatives were calculated, and three new derivatives were selected for synthesis and characterization, namely contorted pentabenzocoronene (cPBC), contorted tetrabenzocioronenes (cTBC), and contorted terabenzofuranylbenzocorone (cTBFBC).

Molecular dopants: Tools to control the electronic structure of metal halide perovskite interfaces
TL;DR: In this paper, the authors provide a short review of recent work on the use of molecular oxidants and reductants on perovskite surfaces, including the mitigation of the surface states, and the impact of these dopants on energy level alignment with substrate and charge transport layers.

TL;DR: In this paper, the authors designed an optical measurement with an external magnetic field to determine the efficiencies of triplet exciton transfer from tetracene to silicon, and they found that a passivation layer of 8 angstroms of hafnium oxynitride on silicon allows efficient three-body excitons transfer around 133 percent.
