Study on long term reliability of photo-voltaic modules and analysis of power degradation using accelerated aging tests and electroluminescence technique

Energy Procedia, 2011
AbstractTo improve PV module's lifetime and reliability, it is essential to understand the mechanisms and causes that degrade module performance over time under different climatic conditions. In this study, our main aim is to correlate the degradation of module power with physical changes that are generated in the cells over time.

Graphene oxide/exfoliated black phosphorus van der Waals heterojunctions for PEDOT:PSS‐free‐based organic light‐emitting diodes achieving excellent electroluminescence performance

FlexMat, EarlyView.
A novel two‐dimensional heterojunction assembled from graphene oxide and exfoliated black phosphorus via van der Waals interactions is proposed to replace widely used poly(3,4‐ethylenedioxythiophene)‐polystyrene sulfonate for efficient hole injection layer in organic light‐emitting diodes, achieving impressive electroluminescence performance.

Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

FlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Highly efficient blue crystalline organic light‐emitting diodes enabled by a hot exciton sensitizer PyPO

FlexMat, EarlyView.
Two different sensitization structures (hot exciton sensitizer type and exciton nanoaggregate type) were integrated into crystalline host matrix. The resulting crystalline organic light‐emitting diodes exhibit low Joule heat loss ratio and high photon output.
