33% is more than enough to power the world without blanketing every inch in solar panels.
Love new technology, always have, but these kinds of advances pale in comparison to JUST PUTTING PANELS ON.
My house is a tiny, tiny (60sq m.... yes 60) house. My smart meter tells me - I pull at absolute max 10KW at any one time (and that rarely and briefly). I pull 8.5KWh / day, on average, over the last 4 years. My house is entirely electric so that's everything - that's heating, lighting, my computers, cooking, appliances, etc. etc. etc.
My roof space is ~30sq m (I have some extra panels on an outdoor shed, my front is NOT covered entirely in panels, I have about 8-10KW of panels). I can satisfy the above by covering my roof space at a less-than-ideal facing, tilted at a less-than-ideal angle, at a less-than-ideal latitude (the UK), and with less-than-ideal panels, having a battery pack consisting of less-than-ideal batteries.
In the summer, I'm constantly in excess (hell, I'm still in excess now and it's nearly October). In winter *sometimes* I have to fall back to grid (but my heating is entirely heatpumps, and they pull a maximum of 800W each, but more like 250W once the temperature is where it should be).
Oh and the above - is an entirely homemade system. I cut and crimped every cable, I lifted, railed and fixed every panel, I joined all the batteries together myself, I fused and RCD'd and MCB'd the entire thing. I operate them as entirely separate to my grid power system (though the new micro-inverters are about to change that as they've been approved in my country now).
If I can do that, so can much of the world, especially with professional deployment, and so SHOULD those portions of the world where it's viable be made to do this.
