Nikos and Ryan formulated a plan for NREL to evaluate one of G2V’s Sunbrick large-area solar simulators. For his part, Ryan believed there was nowhere else better in the world to test G2V’s solar simulators and correct any remaining issues to make their instruments the best in the industry. Ryan Tucker, CEO of G2V Optics, whose technology could do exactly what Nikos was after. With this in mind, Nikos was eventually introduced by his predecessor to Dr. Nikos believed in the promise of LED technology’s ability to activate and probe specific wavelength bands for validating increasingly-prevalent and rapidly-developing multi-junction solar cells. He was interested in the longer-term opportunity for LEDs in solar simulation. More than this, however, Nikos was looking further into NREL’s future. Nikos Kopidakis took over NREL’s PV Cell & Module Performance group, where he began looking for a large area solar simulator. The initial ties were formed, and information passed back and forth. NREL & G2V Optics Solar Simulation Collaboration NREL was intrigued by G2V’s Class AAA LED-based solar simulator technology as a path toward enhancing their testing capabilities and remedying some of their biggest pain points in solar cell testing. The seed of such a partnership was planted at PVSC46 in 2019 when members of the National Renewable Energy Laboratory (NREL) met G2V Optics for the first time. As much as it’s a sharing of growth, however, it’s also a time for sharing problems, with the formation of partnerships to bridge gaps that would otherwise remain deep rifts. ![]() Now, Samsung’s upcoming QD-OLED TVs? That’s worth crowing about.When expert researchers, technology influencers and manufacturers gather at the annual IEEE Photovoltaics Specialists Conference (PVSC), it’s an exciting time for sharing developments and getting invigorated by the progress in the field of solar cell technology. We’ll take what we can get, but we’ll try to keep it in context. Samsung may well have just made life a tiny bit easier with the new Eco Remote. On the other hand, if you’re constantly worried about whether you’re going to have to charge the remote because it’s using this newfangled technology from the sun combined with the same thing that powers those potentially problematic 5G networks and whether your copper 5G chest protector might get in the way - well, we can’t help you there. If you never have to worry about charging the remote, that’s certainly a good thing. We’ll have to wait until we’ve got Samsung’s new Eco Remote on hand for some long-term testing before we know whether this solar power/RF Harvesting thing is worth its weight in press releases and blogger headlines. In other words, have we devolved so much as a society that we cannot handle charging a remote control for a half-hour a couple times a year? Or swapping out a couple batteries? It’s just not that hard to do. My favorite remote, which is end-of-life at this point, is years old but only on its second battery. Apple TV finally has a remote control that doesn’t make me want to use something (anything!) else, and every now and then it tells me to plug it in to charge, which is simple enough to do. Once a year or so I might have to swap out the batteries. Even the most prevalent of the bunch don’t do a whole lot to inspire. I’ve spent more than my fair share of time poring over remote controls, particularly so many for so long that have been pretty awful. Presale starts nowĭigital Trends’ Tech For Change CES 2023 Awards Samsung prices its 77-inch QD-OLED at $4,500. What Samsung really means is that this isn’t a remote you’ll have to worry about charging. Never mind the fact that there certainly is some sort of energy storage device inside - Samsung says as much. Samsung bills the Eco Remote as a way for customers to “take a literal hands-on approach to reducing their eco footprint.” That’s due in part to it using recycled materials, but also because it uses solar power and what’s known as “RF Harvesting” to give what it calls “a battery-free experience.” ![]() ![]() SamsungĮnter Samsung’s new Eco Remote, announced this week at CES. (Batteries, after all, are organic devices and will, eventually, die.) And that means the company that produces the product can do so at a slightly lower cost. The device in question is going to work better and longer. You’re going to be happier with the experience. The less you have to worry about charging it, the better off everyone is going to be. When it comes to electronics - anything with a battery, really - there is but a single thing we need to remember.
