How far does solar have to go before it’s ready to scale up? 🛰️ engineering
The new cell uses the company's patented Inverted MetaMorphic solar cell technology, which has a conversion efficiency of roughly 33.3 percent in volume production.
What's more, it is more than 40 percent lighter than typical space-grade solar cells. Reduced weight, of course, is a currency in and of itself when it comes to space missions, which can cost millions more depending onIn its press release, Rocket Lab says"the IMM-β solar cell is expected to be the highest efficiency space solar cell technology in high-volume production. The cell boasts an average 33.
The statement adds that,"the IMM-β is also a radiation-hard cell with a power remaining factor of 87% after exposure to 1-MeV electrons at a fluence of 1E15 e/cmRocket Lab also explains in its statement that the new technology is undergoing final space qualification testing, and that it is expected to be ready for commercial use later this year.
"We’re excited to bring to market this next significant step in solar cell performance," said Brad Clevenger, Vice President & General Manager, Space Systems Power Solutions."In partnership with our colleagues at the Air Force Research Laboratory , we're not only commercializing the world's highest efficiency and lightest weight space solar cell, we're doing so at the most competitive cost of any IMM technology to date.
