In PM6:Y6, electron–hole pairs split with no help from the electric field and an activation energy of only 6 meV. The electrostatics of Y6 offset the Coulomb pull.

Non-radiative recombination costs Y6-type organic solar cells 200–300 meV of voltage. Blends that emit light more brightly are the route past 20%.

Is your organic solar cell's voltage loss 0.51 V or 0.62 V? Same device — only the optical-gap definition changed. Interactive explainer of our Adv. Energy Mater. 2018 report on comparing voltage losses consistently: https://t.co/vG5MdPn96w

The essence of a Physics-Informed Neural Network (PINN) is that it's a type of AI that learns not just from data, but also from the fundamental laws of physics.
Instead of being a "black box", a PINN is trained to simultaneously 1) Fit the Data and 2) Obey the Physics.

This is my understanding of metal-semiconductor contact, including a rectifying contact and an Ohmic contact made on n-type semiconductors.

How to understand GIWAXS data: 1, incident X-rays scatter off the sample's ordered structure.
2, the scattered X-rays form a diffraction pattern on a 2D detector.
3, we analyze this pattern (a map of reciprocal space) to determine the structural arrangement in real space.

Delocalized electrons aren't confined to one atom, instead forming a conductive "sea" in crystals or creating resonance in organic "segment". This principle of spatial spreading dictates vital material properties, from electrical conductivity to chemical stability.

This figure illustrates how scientists can measure an event that is faster than their detector's response time. By mathematically removing the "smearing" effect of the instrument (instrument response function, IRF), the fast signal can be recovered.

I cannot agree more that the best state of life is waking up in the morning and can’t wait to do something you love. Time to ask myself if what I’m doing can really make me feel that way. https://t.co/5N9Ku1NOOJ
