Adhesive degradation during field and accelerated aging of photovoltaic modules

Abstract

Extending photovoltaic (PV) module lifetimes beyond 30 years is a goal of significant priority. A challenge that must first be addressed, however, is the development of a predictive reliability model that captures the synergy of terrestrial stressors on module degradation, particularly at encapsulant interfaces. 181 more words

The Impact of Climate Condition on the Optimal Operation of Direct Coupled Photovoltaic Solar-Vehicle Systems

In a photovoltaic solar-vehicle system, many factors may present disturbances and thus affect its operation. Among the disturbing parameters are the variable output voltage of the photovoltaic generator (GPV) and unbalanced irradiation throughout a day, as well as both the variable load (considered as a resistor in our case) and duty cycle. 171 more words

A New Class of Coating Material: Self-Healable and Ultrahydrophobic Polyurethane-POSS Hybrids

Researchers from India first functionalized polyurethane using a novel chain extender (FA-FGE) which was obtained from the reaction between furfurylamine (FA) and furfuryl glycidyl ether (FGE) and then Diels–Alder (DA) “click” reaction was used to graft this functionalized PU with maleimide functionalized polyhedral oligomeric silsesquioxanes (POSS maleimide isobutyl, POSS-M).  103 more words
