In this video we’ll explore the world’s fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.

Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.

Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.

While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.

Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.

Fantastic presentation on a solar technology I didn't even know existed. I always love hearing about newer and better technology. In my heart I know you'll solve the problems surrounding early degradation. Cheaper more cost effective so what's not to like? Scientists like yourself always amaze me. Thank you for everything you do to make this world a better place to live. Energy costs have a lot to do with making that happen. Know that you're very much appreciated!

I truly appreciate the honesty in this video presentation. They ask hard questions and point out both the positive and negative attributes of this technology. Over 50 years of R and D with solar and we are still waiting for a significant break through. I do hope that Perovskites prove to be that breakthrough.... The solar cell and the battery still have a lot of improvements to go through before they become a viable, national energy sources.

This got me much more interested and educated than severals hours our lessons on perovskites for material science. I was surprised there was no mention of the Lead (Pb) as most issues with perovskites used to be that we didn't know how to do lead-free perovskites crystals. I would have liked to know more about the toxicity of these coatings

This was a great video. As someone who is going to college for materials science, it was cool to see the concepts brought up in ways that make it easy for a layperson to understand, and also very cool to see the guy from the company be honest about the downsides to perovskite solar cells.

"Stability and Degradation: Perovskite solar cells have demonstrated competitive efficiencies with potential for higher performance, but their stability is quite limited compared with that of leading PV technologies: They don’t stand up well to moisture, oxygen, extended periods of light, or high heat. To increase stability, researchers are studying degradation in both the perovskite materials and the contact layers. Improved cell durability is paramount for the development of commercial perovskite solar products.

Cool to see more efficient solar power models being researched. Finding efficiency is the crux of engineering.
Giorgia Angelia
Extremely well explained and illustrated. Very easy to understand by anyone no matter the level of scientific knowledge. Well done and keep up the good work!
Love the simplicity yet the complexity in his explanations. Can’t wait to see what happens next.
This is definitely something I hope becomes commercially available soon because I inted to heat my house using Geo-thermal and I'd like Solar Panels (with w/e batteries I can get for energy storage for cold/night time usage) to be what is giving the geo-thermal unit all the energy it needs to operate at 100%. Not needing to burn wood or use oil/propane etc. is a dream of mine but living in NH I worry about how many solar panels I'll need to get so that (even in Winter time) I never have to worry about having enough power to run my geo-thermal unit. I haven't done any research into how much solar panels are going to cost me but, as long as I can afford it, I have no doubt I'll be needing dozens for year round powering/usage.
This was a good video and I'm especially happy you went into the challenges it faces although I always end up frustrated not really understanding how they go about improving the poor aspects. Like, what specifically allows for one of these substances to be more durable to heat and how do they go about trying find it?
Outstanding presentation. Super interesting details direct from the company, including their manufacturing process

I remember reading in some magazine around 2000 about 2 technologies for solar. 1 was a paint for your house that would insulate the house (low R factor) and allow solar use. And the other was a film for use on the windows that would still allow light to pass through, but let you hook it into a solar system. I was hoping to really see both develop and this looks sort of like #2. I hope it come to fruition.

Mr. Jean does an excellent job of explaining Swift Solar's approach. I also appreciate his candor on his current priorities for scaling production, his manufacturing and testing methodologies, what the limitations currently are (longevity and environmental ruggedness), the current market applications, and his priorities in broadening its utility by addressing the longevity issues.
Harby Variah
So informative and I didn't know there was better technology, instead of the existing solar panels systems.

Graphene could serve as the transparent electrode. Graphene is almost a one-atom-thick superconductor and can be applied using chemical vapor deposition (CVD). CVD is currently the front running process for making graphene.
Very excited indeed! I was a little surprised to not see a short mention of the Zebra ISC or Sunpower Maxeon 3rd gen. solar cells. These cells have an efficiency close to 25% and are already in use in some sectors. Can these become even more efficient in the future?
John Byrom
I have been pro R and D on solar, but against mass implementation, as we are going too fast before the tech is ready on that scale. This could truly be a game changer. Keep the R and D going.
Braedon Hansen
Fantastic video, both your enthusiasm and optimism for this new developing technology radiated through the script!
Great info guys!

At a 1/15th cost of solar panels, at 20 year lifespan seems reasonable at least on a consumer level which are more less the same life span as most current solar panel tech, let alone roofs, vehicles, and most applications. It seems that really isn't an issue. And if it's better for the environment with more abundment materials cost.. it seems like they're almost ready to launch.
