Proud to share our latest publication in the Japanese Journal of Applied Physics on the spectral irradiance distribution at AM1.5 in the Arabian desert and its influence on the current balance of multijunction PV technologies. This work highlights how real desert spectral conditions in Abu Dhabi - even at local AM1.5 and in clear-sky conditions, which are so abundant in the UAE - can significantly deviate from the standard AM1.5 spectrum, leading to current imbalances of up to 10% in advanced tandem and triple-junction PV devices. The findings reinforce the importance of PV characterization in technology development, especially for desert regions where solar deployment is rapidly expanding. Among all coauthors, a very special thank goes to: Min Hsian Saw, PhD for the tremendous experimental and analytical work behind this study; and Mohamed Alremeithi for his help and for presenting the work during the last PVSEC in Bangkok. I am particularly proud that this research was conceived, measured, and developed in the UAE, leveraging local infrastructure and expertise. #SolarEnergy #Photovoltaics #Perovskite #TandemSolarCells #PVResearch #MadeInUAE #UAE #RenewableEnergy #DesertSolar
