Perovskites - where now?

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.

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.

the company

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

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.

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.

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...
