Upright Orientation of Asymmetric Conjugated SAM Enables High-Performance Perovskite Solar Cells.

Self-assembled monolayers (SAMs) are promising hole-transporting interlayers for inverted perovskite solar cells (PSCs) owing to their ultrathin thickness and tunable work function. However, conventional SAMs such as Me-4PACz tend to adopt lying-down or tilted conformations on substrates, leading to disordered dipole o...

E$^2$-OPSD: Taming Entropy Overshoot in On-Policy Self-Distillation

On-policy self-distillation (OPSD) provides dense token-level supervision without a second model: one network acts as teacher with the reference solution and as student with only the problem. We identify a specific failure mode of this recipe. During training, student token entropy rises past the teacher's and remains...
