Breathless reporting, but at an input of 100 w/m², this is not going to make hydrocarbon fuels obsolete. Ever. It’s a kinetic problem, if not thermodynamic.
Not enough CO2 content in the air to make these solar cells pay off. They will produce hydrogen gas too slowly and good luck gathering the hydrogen gas from an array of these newly invented solar cells.
What you have is a proof of concept and did the taxpayers get dinged for it?
The average insolation on the surface of the earth on a cloudless day in the temperate regions is 800 w/m^2, over an 8 hour day about 7 Kwhr of energy would be expected to fall on every sq meter of earth.
Petrol has a HHV of 34 kwhr the max theoretical efficiency is around 90% for photosyntetic reasons so 6 sq meters of surface area would produce a gallons worth of fuel energy per day. The tropics have significantly higher insolation numbers almost 1000 w/m2 and 12 hour day light hours.
Every second of every day more solar energy falls on the surface of the earth than every gallon of fossil fuel humanity has ever burned in all of human history by a couple of orders of magnitude the amount of energy falling on the surface of the earth is staggering.
