Scientists Just Set a New World Record in Solar Cell Efficiency

Scientists Just Set a New World Record in Solar Cell Efficiency thumbnail

Improving the efficiency of solar cells can make a huge difference to the amount of energy produced from the same surface area and the same amount of sunshine, and another world record has been beaten in the push for better yields.

Researchers have now hit an efficiency of 29.15 percent in the perovskite/silicon tandem solar cell category, which is just one of several different types of cells. There are currently a variety of different technologies in use to convert solar energy into electricity.

For this type of panel, the long-term target of more than 30 percent is now tantalisingly within reach. The latest lab tests edge ahead of the maximum 28 percent efficiency that perovskite/silicon cells have managed up to this point.

“Tandem solar cells that pair silicon with a metal halide perovskite are a promising option for surpassing the single-cell efficiency limit,” write the researchers in their published paper. “We report a monolithic perovskite/silicon tandem with a certified power conversion efficiency of 29.15 percent.”

Perovskite and silicon have actually been developed separately as semiconductor materials for solar panel use: silicon cells have been around for longer, and are currently the standard in solar farms around the world.

Perovskite is the up and coming new challenger, which scientists think could eventually eclipse silicon in terms of usefulness.

That’s why scientists have long been experimenting with different perovskite compound combinations and adding other materials – silicon, in this case. The so-called tandem cell uses two semiconductors that can capture two different parts of the light spectrum, extending beyond infrared light (captured by silicon) into visible light too (captured by the perovskite compounds).

More good news is that putting perovskite and silicon together doesn’t substantially add to the cost of making the panels. Keeping the price down is important for getting solar technology rolled out as far and as quickly as possible.

In this new research, the 29.15 percent efficiency record was managed with a 1 cm x 1 cm (0.4 inch x 0.4 inch) panel, so some serious scaling up will be required. The team says that should be possible, however. After 300 hours of simulated use, the tandem cell retained 95 percent of its original efficiency, which is another promising sign.

The new record was actually first reported earlier this year, though the peer-reviewed paper detailing the feat has just been published. The scientists used specially tweaked layer compositions for both connecting the electrode layer and keeping the two types of cell together in order to reach their new record.

It’s another moment to celebrate, but the scientists aren’t stopping: previous research suggests that tandem solar cell technology should be able to reach efficiency rates of well above 30 percent, and the team says “initial ideas for this are already under discussion”.

The research has been published in Science.

    I wish JuanP would quit with the stupid posts with socks and other nonsense!

    “Everyone wants to describe the day that the light switch flipped and the C.D.C. was sidelined. It didn’t happen that way…. It was more of like a hand grasping something, and it slowly closes, closes, closes, closes until you realize that, middle of the summer, it has a complete grasp on everything at the C.D.C.”

    -Kyle McGowan, a former chief of staff of the US Centers for Disease Control and Prevention (CDC), speaks out about political interference at the agency.

    supremacist, FYI, the US has the THIRD most polluted river, the Passaic, and the EIGHTH most polluted, the Mississippi, out of the top ten, according to the World Atlas. The Mississippi River drains about half of the US. Thousands of miles of pollution.

    The seventh most polluted is the Marilao River in the Philippines just north of Metro Manila and about 50 miles long.

    https://www.worldatlas.com/articles/the-most-polluted-rivers-in-the-world.html

    Again, Amerika is NUMBER ONE with TWO of the most polluted rivers and is supposed to be one of the richest countries in the world. Hah! Third World all the way and going even lower.

    BTW: Amerika is even worse than Bangladesh! LMAO!

  9. makati1 on Thu, 17th Dec 2020 4:25 pm 

    Amerikans are number one at hypocrisy. Always trying to divert attention from their own bullshit by trying to make others look worse. Like supremacist above. Look in the mirror Amerikan tax slaves/serfs. You are going down.

    The PO moderators are making changes and seriously considering eliminating this news section’s comments threads and leaving only the moderated comments section and blocking Davy AKA REAL Green, etc., etc., etc.
    We all received a PM about it on the moderated side. Apparently many people have been complaining regularly about his behavior.

  11. zero juan on Thu, 17th Dec 2020 5:18 pm 

    quit your whining stupid

  12. JuanP on Thu, 17th Dec 2020 5:25 pm 

    I don’t know if they will give him a final warning or simply ban him. The people who post on the moderated side are voting on it. I voted for kicking him out without a warning.

  13. JuanP on Thu, 17th Dec 2020 5:28 pm 

    All of you here can help to get Davy banned by PMing the site admin.

  14. zero juan on Thu, 17th Dec 2020 5:31 pm 

    like I said lunatic, stop your whining. You are being trolled, troll. take you punishment like a man not a pussy!

  15. makati1 on Thu, 17th Dec 2020 5:32 pm 

    Close down PO totally. It will not be missed. Davy should have been banned years ago when he started putting people down instead of debating.

    A lot of people are suffering from a mental health crisis. It’s a global problem and nobody gives a damn. No magical pill will fix this.

    If P.O. is closed down, that troll with sock puppets won’t be missed.

    Triple junction solar cells have been edging towards an efficiency of 30% for about 2 decades now. Not exactly cutting edge.

  27. peakyeast on Mon, 4th Jan 2021 1:40 am 

    I purchased 39% triple junction cells from Spectrolab some 15 years ago….
