I've come in contact with someone involved in using perovskite in solar cells. As with most new technologies, the pathway to commercialisation is convoluted. As an alternative to silicon cells on panels there is some potential but many a challenge.

Perovskite Solar Cells: Promises and Challenges

Perovskite solar cells are a promising technology for generating clean energy from the sun, with rapidly growing photovoltaic potential.
www.prescouter.com

What I understand is that there are many companies and universities researching its applications, and at varying levels of success towards a better mousetrap.

While naturally occurring, perovskite can be made in the lab.
As a solar cell, a 40 per cent efficiency has been reached in the lab. It is likely that 25 per cent will be the norm for commercial product.
Rather than silicon based crystals, the perovskite layer can, beneath a protective surface and with a conductive layer underneath, generate enough charge to power intermittent use devices using just a capacitor.
These devices include channel changers and aircon controls.
Perovskite charging works in low / ambient light, and NO need for direct sunlight.

My guy claims they are close to production, but need funding to build a factory (at Wagga?). And that won't come until there's a contract. NDAs and MoUs don't cut it.

Greatcell Energy

I mentioned FGR to him, and he said they're working with them , but the amounts are small (miniscule?)

from post #49
"" ..Joint Development Agreement signed with Greatcell Australia* for development of perovskite solar cells
* Australian-based Greatcell specialises in the development and utilisation of photovoltaic technologies, specifically Perovskite Solar Cells, to convert low and ambient light to electricity. These solar cells are designed to be low cost and highly efficient compared to other solar technologies, but currently utilise a gold layer.

Under the agreement, First Graphene and Greatcell intend to jointly develop graphene composites and formulations to be used to manufacture more efficient and even lower cost PSCs. The graphene-based solutions remove the need for a gold layer, which could reduce the material input cost of the cell by circa 80%....

also perovskite is mentioned in "The Future of Energy Generation and Storage" thread

Getting ahead of themselves, maybe

A Perovskite Makeover Could Make Green Hydrogen Happen

Perovskites have already made their mark on the solar industry, and now attention is turning to green hydrogen production.
cleantechnica.com

the key takeout, as I understand is in an early para:

"Perovskites are synthetic versions of the mineral perovskite. They have already begun to emerge as a potential game-changer in the solar industry, with the promise of raising solar conversion efficiencies while lowering costs (see lots more coverage here) ..."

low light , infrequent use, say something like a TV channel changer.
...80 million units a year , replace 160 million batteries. And that's just one electronics company.

Start small...
 
another player, but starting small.

Swiss perovskite startup sets up indoor solar cell manufacturing

Indoor solar cell developer, Perovskia Solar, is setting up a factory in Switzerland that may reportedly print 1 million of its custom-designed perovskite devices annually. It targets the market for self-powering consumer electronics and internet-of-things devices, such as fire-alarms, fitness...

Switzerland is where a lot of the early research was carried out. The race is on for low cost manufacturing.
 
@Dona Ferentes I note the mention of perovskite being beneath a protective layer in the cells. Does this indicate it is more fragile than silicon? I only ask in relation to solar cells being exposed to storm conditions in the tropics and elsewhere for that matter.

I only ask as you seem, and admirably so, to be going down the perovskite rabbit hole.

The P layer is between a conductor (Graphene?) (straight to a capacitor) and an external sealant, as perovskite can be broken down by moisture.

it's my understanding these are production issues that are now being addressed. Quite a few players as you can see, who will get to commercial stage first?

As they say, wear like iron, wash like plastic. Strength, durability and flexibility... and cost effective. Yet another Holy Grail.

When the Jap PM sets it as a goal, then you know the big keiretsu are behind it.
 
the local outfit has renamed, now with an updated website.

Halocell

halocell.energy

The former chair, an older guy in photos from 2 years ago, has been eased out.

Some of the other companies doing research and product development are incorporating a Silicon layer, and also Pb in the perovskite. Halocell is aiming for neither, and a 25 per cent conversion efficiency.
 
I can see where this'll lead to, a monitor that can function as a highly advanced biometric harvesting spy device...
 
First Graphene Limited (ASX:FGR) has secured an agreement with Halocell Energy to supply graphene for the manufacture of perovskite solar cells.

The initial two-year agreement will result in the Company providing its leading PureGRAPH® to the New South Wales-based manufacturer for use as a high-performing coating for perovskite solar cells.

By incorporating PureGRAPH®
into its products, Halocell Energy can expedite its manufacturing process and enhance light absorbing performance, which will enable the company to scale up commercial production to meet demand.

Halocell Energy will release its first commercially available indoor perovskite solar cell module this month, which can be used to charge small electronic goods, replacing disposable batteries.

These graphene enhanced modules are up to five times more efficient than conventional silicon solar cells. They are also more cost-effective, with Halocell Energy demonstrating graphene can reduce manufacturing and materials costs by over 80% as the need for high-cost conductor materials such as gold and silver are eliminated.
 
No please keep using silver .....
Qldfrog a shiny metal bug.
Interesting 5x more efficient?
That would be interesting
