Cooling photovoltaic panels with air convection – Parametric environmental and economic analysis with case studies

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Photovoltaic (PV) panels generate electricity due to photoelectric effect, harvesting solar radiation from the sun. However, the hit of photons on the upper surface of the PV panel increases its temperature, and as a result, decreases its efficiency. The

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

Advanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.
