Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Experimental Test Setup of an Airwall to Reduce the Convective Heat Loss in Solar Thermal Cavity Receivers

SolarPACES Conference Proceedings, 2023
An experimental setup is presented which allows to experimentally determine the thermal heat losses from a heated solar cavity  receiver with an airwall. The setup is a ‘near-full-scale’ replica of a receiver, which ensures that the characteristic fluid

Radiation hydrodynamics in simulations of the solar atmosphere [PDF]

, 2020
Nearly all energy generated by fusion in the solar core is ultimately radiated away into space in the solar atmosphere, while the remaining energy is carried away in the form of neutrinos. The exchange of energy between the solar gas and the radiation field is thus an essential ingredient of atmospheric modeling.

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost

Advanced Functional Materials, EarlyView.
A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.

Solar Energy on Demand: A Review on High Temperature Thermochemical Heat Storage Systems and Materials.

Chemical Reviews, 2019
Among renewable energies, wind and solar are inherently intermittent and therefore both require efficient energy storage systems to facilitate a round-the-clock electricity production at a global scale.

Solar Neutrino Data, Solar Model Uncertainties and Neutrino Oscillations [PDF]

Phys.Lett.B299:94-98,1993, 1992
We incorporate all existing solar neutrino flux measurements and take solar model flux uncertainties into account in deriving global fits to parameter space for the MSW and vacuum solutions of the solar neutrino problem.
