Scientists develop mega-thin solar cells that could be shockingly easy to produce: ‘As rapid as printing a newspaper’::These cells could be laminated onto various kinds of surfaces, such as the sails of a boat to provide power while at sea.
First, the thickness factor plays into flexibility. Just imagine surfaces of every shape being covered in solar cells. Flexible panels could also be less prone to breakage.
Second, with “as rapid as printing a newspaper”, this might be a major cost-reduction thing, even on top of the process needing less high-pure Si material.
This might make solar power generation more attractive even if the efficiency would be lower than other methods, because this would drive the ratio $/kw down.
Kind of like these? Flexible solar panels are not a problem. And no, being newspaper thin will never be stronger than mounted on rigid surface. If it bends it has a definite limit in number of times you can bend it.
As for “printing a newspaper” and rapid production, when I see it I’ll believe it. At the moment it’s nothing more than speculation as they themselves have not made it yet. Every manufacturing process starts slow and then speeds up as process is optimized. The problem is whether there is a financial incentive to start producing in the first place.
By “flexible” I did not imply “use it as a hinge”. It was more like: “you can install it on a non-flat surface”, e.g. by gluing it down. Now that surface would provide the needed overall stability. Imagine having you cars roof and engine hood being completely covered in solar cells - or basically be a solar cell. No, you would not be able to drive it as an EV with the amounts of power provided, but it could trickle charge a battery, or power a fan in hot weather so the interior will not be boiling when you return to your vehicle after a day at work.
We already have the panel type which is glued on. But I guess it remains to be seen whether there’s a financial incentive to mass produce this.
Indeed. Price is the key issue.
