Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.

Reliability Oriented Design Tool For the New Generation of Grid Connected PV-Inverters
Nicolae Cristian Sintamarean,Frede Blaabjerg,Huai Wang,Francesco Iannuzzo,Peter de Place Rimmen +4 more
TL;DR: In this paper, a reliability-oriented design tool for a new generation of grid-connected photovoltaic (PV) inverters is presented, which consists of a real field mission profile (RFMP) model (for two operating regions: USA and Denmark), a PV panel model, a gridconnected PV inverter model, an electrothermal model, and the lifetime model of the power semiconductor devices.
High-Speed Wireless Indoor Communication via Visible Light
TL;DR: The performances of systems relying on base-band and DMT transmission show that data rates of more than 100 Mbit/s can be expected despite the rather low bandwidth of the system.
