Solliance realizes first up-scaled Perovskite based PV modules with 10% efficiency

May 9, 2016, IMEC

Solliance demonstrates a record 10 percent aperture area power conversion efficiency for its up-scaled thin-film perovskite photovoltaic modules. The efficiency was measured on an aperture area of 168 cm2. Twenty-five cells were serial connected through an optimized P1, P2, P3 interconnection technology. The PV module was realized on a 6x6 inch2 glass substrate using industrial scale-able slot die coating in combination with laser patterning. Further, the PV module was packaged by applying a flexible barrier using a lamination process.

This result could be realized due to the intensive collaboration within Solliance. Based on previous optimization on 16 cm2 modules, the Solliance team was able to quickly transfer this to a 6x6 inch2 sized using the developed blade coating process and the optimized mechanical patterning technology. In this case a 156 cm2 aperture area module with 10 percent efficiency was realized comprising of twenty-four interconnected cells. This was then used as starting point for the realization of above mentioned 168 cm2 PV module.

These results demonstrate the up-scalability of this new thin film PV technology. Apart from the electrodes currently used, all layers can be processed in ambient environment and at temperatures below 120⁰ C. This shows the low production cost potential of this new emerging thin film PV technology. Further, the deposition and interconnection technologies used for obtaining these results are industrially available for Sheet-to-Sheet as well as for Roll-to-Roll manufacturing. The latter allows for creating high volume production in the future.

The current world record efficiency of a small lab scale perovskite based PV cell is 22.1 percent. "The challenge is to upscale perovskite cells to larger size industrially process-able modules with high efficiency and long lifetimes at low cost. The current result, presented on an aperture area comparable to standard commercial silicon solar cells, shows that Solliance, with its in depth know how on processing of organic PV and CIGS and its vast Sheet-to-Sheet and Roll-to-Roll pilot production infrastructure, is excellently placed to realize this upscaling. These 10 percent up-scaled perovskite based PV modules are first and important steps in this development. We are confident to boost quickly the up-scaled Perovskite based PV module further above 15 percent by using very low cost materials and processes. But besides demonstrating the up-scalability of these highly efficient Perovskite based PV devices, we are also currently working hard to stabilize further the performance of these devices under real life operational conditions", explains Ronn Andriessen, Program Manager of the Perovskite based PV program at Solliance.

Solliance is conducting advanced research on the development of Perovskite based PV modules and its applications with its industrial partners Nano-C, Solartek, DyeSol and Panasonic. With this result the Solliance R&D partners and their industrial partners demonstrate the strength of their research framework for the development of industrial Perovskite based PV modules.

Sell your coal-based powerplants. Replace your car with an EV soon, because the world is changing.

".. and see electric bill skyrockets with all EV feeding from an intermittent electrical grid, an amazing world-changing downhill."
-------------------------------------

My electricity bill contains the costs of both the electric vehicle, and the house, too, and with the PV system was minus $28 last month. That means we generated that much in credits for later.

How much did you pay for heating, lighting, and transportation?

and with the PV system
illusion
It is not your PV that is charging your EV; it is from the grid. Law of supply and demand, with more and more EV charging from the grid, electricity prices skyrocket. Only rich people will be able to pay; poor people forced to go back to cave ages, pitiful human downhill as already happening in Germany with bills twice costly than in France.
Disconnect from the grid and try to use only your PV to charge your EV and to supply your home, and fell into the reality.

Yes, Willie, by integrating with the utility, I can produce and use when I want. It is called technology of civilization. By trading electrons when we have them, we all win.

Did you tell us how much you paid for heating, lighting and transportation?

Do it. We can compare.

Not bad for a first effort. They first started looking at these in 2009, and the first really good ones came along in 2012. In a few years, these may capture the market. With recent advances obviating CIGS, they may even be pretty environmentally friendly by 2020 or so. And they're cheap.

I can't even imagine the mentality it takes to object to cheap solar cells.

Free energy is falling from the sky. Get some. This is duh.

What's the problem here? Luddites infesting the site? Coal mine owners or oil barons? At least give some sort of reason, fer cryin' out loud.

As far as German household energy prices, it appears that the extra cost is due to taxes levied to fund the Energiewende, according to Bloomberg:

Wholesale prices are at their lowest in 12 years as of last August. That trend has continued to date.

German consumers have the lowest rates in over a decade:

If you're going to make stuff up, @Willie, at least check the facts first. It doesn't appear you have the slightest clue what German electricity rates are actually doing.

And dropping.

You forgot that part.

Try to keep up.

On edit, just for the record:
Cost of power for supplier (21.3 %)
Grid charges (24.6 %) <-Determined by the government
Renewable energy surcharge (22.2 %) <-Energiewende tax
Sales tax (value-added tax) (16 %)
Electricity tax (7.2 %)
Concession levy (5.8 %) <-Payment for public lands the electric lines cross
The rest are on the close order of 1%.

So basically Germans pay 25% for the actual electricity, and 20% for delivery of the electricity, and the rest is government charges.

Blaming solar is shaking your fist at the sky.

For the mathematically challenged, that means that the German government determines almost 80% of the cost of electricity, and surcharges and taxes form over 70%.

Oh, and I got the percentages backwards: 20% for the actual electricity, 25% for the delivery of the electricity.

"Soon", being when we'll be able to actually buy one? The world is changing, yes, but people's situation won't change that easily. You can hardly ask for people to jump from a cliff with a parachute if they don't really want to in the first place. And if there is NO PARACHUTE at all....heh, ask again?
The world is changing. But there are people who can help it to change, and those waiting the changes to change themselves, not because they don't want to change, but because they can't do it as easily.

Look for all the negatives you can, . . but it will happen. Major changes in infrastructure, which is what this is for home-owners and car owners, take long times, since they are major investments. We talk about decades, but that is fast for infrastructure.

Prices are already changing as fast as the technology.

Hide and watch.

-But we know you don't own an electric vehicle and so the rest of this is probably bullshit as well.
