Actually I would think that is a considerable drop in the price. many of the HP ink cartridges have only 2-10 ml in them, at an average of 5ml that gives you 900 catridges to the galon. guessing the average price per GAL at moment is somewhere north of $20,000
I just did some quick look-ups for HP ink. It's $2,000-$3,000 dollars per gallon for black ink, and about $5,000 per gallon for the tri-color cartridges.
More than I expected, but then, if I need more than my 20 years old laser printer can deliver, I'd go to.. I was going to say Kinko, but that has not been around for ages. The last time I needed something like that, I just printed it in a hotel's lobby FedEx Office. And now that I think about it, that's what Kinko's got renamed to, isn't it?
I've been in the photocopier/printer business for almost 40 years.
The ink for black, other than the pigment, is the same as the colors
magenta, yellow & cyan.
In the toner business, the photoconductive drums for black work just as
well for the color drums. We swap them all the time, for troubleshooting
purposes. That means, other than the pigment, it's the same toner, regardless
of color, but, using the same price model as ink, black is say 150 bucks for
a cartridge of toner, but, the other 3 colors
While seemingly initially useless for powering a home, integrating something like this with something like prosthetics in a way that could enhance or enable otherwise disabled or disadvantaged people is a clear path to follow. You don't need a lot of power (right away, anyway) and one could theoretically and "essentially" print out a replacement solar film in no time.
It's too bad the powers that be will never let this be an otherwise affordable way to help those in need.
There are reasons that trees don't walk around. Energetic considerations is one of them. This might be useful to power, say, hearing aids, but where to you put the photoelectric panels?
Could be a game changer, imagine painting the entire body of an EV or a hybrid like this to charge the batteries. Or a roofing material for construction.

Don't expect to ever see a substantial solar car powered by the light that hits it. Cars take a LOT of power. Even in a desert at high noon the light striking a car just doesn't have enough energy to be comparable.
A horsepower is 3/4 kW. Full noon sun is about 1 kW per square meter. With extremely efficient cells you could potentially capture enough energy to have motive power comparable to a horse buggy.
Yes there are "electric car races". But these are purpose-built ultralight vehicles comparable to bicycle-with-wind-cowling technology. For something more car-like, a day's desert sunlight might charge your batteries enough give you a couple slow miles of travel. "Supercar" designs - ultralight composites, synthetic tire materials, extremely efficient electric drive with regenerative braking, aerodynamic body shapes - might approach usability. But you have to carry the driver and passengers, power train, batteries, running gear, wind deflector cowling, and solar panels. That's a lot of mass to fling around, and some of it (e.g. the humans and payload) isn't subject to

The guys working on ultra-thin inkjet solar panels are just doing fundamental research in chemistry. They are diving down a rabbit hole that doesn't provide any benefit I can see over existing technologies.

have had plastic roll-to-roll screen printed solar sheets for years.
Why would you use the inkjet system in BeauHD's article to slowly print solar cells when you can use mass-manufacture screen-printing techniques to print solar cells on plastic rolls in bulk, then cut them up later?
As far as I can see, the research in this story is a step backwards from existing technologies, and the reporter can only make it look good by ignoring everything that already exists.
Odd that the people in that article have a 2-3 year lifespan problem.
I did work c. 2004 for a company in MA that had organic roll-to-roll at higher efficiencies and longevity than that but it still wasn't commercially viable.

Yes, this is fundamental research in chemistry, and, for solar power, does appear to be a dive gone down the rabbit hole. That's the reality for the vast majority of scientific research. For every game-changing, new and improved, commercially viable product or process resulting from any individual project, there are hundreds, if not thousands, of total failures.

Not just the roof, the exterior walls. House paint that generates power.
Cars don't have enough surface area to make use of solar power, and this is not at all aimed at rooftop solar use. Thinness and flexibility are not really important there, durability and efficiency are.
