20% more than leading top efficiency cells would be 26% efficiency mass-produceable solar cells. IF they had that, they would not waste their time making a car, they'd be to busy diving into huge pools of money, having just made the world's most efficient mass-produceable solar cell by far, and thus become instant billionaires!
- bkanber 7y agoThere's no claim that the cells are operating at 26% efficiency; they just claim that, in aggregate, the system is 20% more efficient than traditional systems. There is an important distinction there.
- dmitrygr 7y agomodern DC-DC is already 96+% efficient. LiPo charging is well understood too. Where is the extra efficiency coming from, other than the hot air out of the marketing department room?
- syntaxing 7y agoTotally agree how the thermodynamics and the economics doesn't add up. Solar panels on cars never really made sense for a reason. The view factor and efficiency of a solar panel on a car would produce very little energy. I would be surprised if it's more than 500W without some sort of breakthrough technology. People forget that 50 kWh (the standard range of a Model 3) is a shitton of energy. A full roof can barely keep up with those number, let alone a car amount of solar panels.
