pv magazine: All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

Scientists from the Central University of Jharkhand in India have simulated a new all-perovskite two-terminal tandem solar cell. It reportedly has a 13% higher efficiency than similar devices with the same materials at the research level.

Perovskite has the potential to significantly reduce the cost of panels but to date they have suffered from lower efficiency and poor durability. Tandem cells (perovskite over silicon), though, have achieved better efficiencies than silicon alone.

Grey Matter: Bill McKibben - Renown Environmentalist - Reclaiming the Climate

October 4, 2022

Bill McKibben is a life-long environmentalist, activist, journalist, and author who has written extensively on the impact of global warming. In our conversation we review the significance of recent climate legislation, the technological alternatives to fossil fuels, and the ways and means currently at work to reclaim the climate – with special focus given to what the Baby Boomers can do.

The average family may shoot four thousand photos in a year. If you have been taking pictures since the iPhone 3G came out in 2008, it means that now, after 14 years of a trigger-happy existence, you are inundated with over 50,000 photos. And you probably cannot find a perfect shot from a vacation you took just three years ago.

Enter personal photo curator Isabelle Dervaux, who can make sense of your photo mess and get your collection organized and, more importantly, functional.

The new, 10th-gen iPad only supports the first-generation Apple Pencil, meaning that it requires an adapter to charge separately via a wired connection since the device has moved to USB-C.

NYT: …drones that Russia is using to attack Ukraine.

The latest Russian attack on the Ukrainian capital, Kyiv, on Monday was preceded by a sound that has become increasingly familiar in the war: the buzz of a small engine, like a lawn-mower or moped, that signals the arrival of an exploding Iranian-made drone.

Russia is now playing the role of Nazi Germany in the Blitz.

Is 63 years enough warning?

The Tyee: The Petro Elite Were Warned of Climate Calamity in 1959

Among them was Sun Oil head Robert Dunlop, who proceeded to exploit the tarsands of Alberta. Excerpted from ‘The Petroleum Papers.’

However, Dunlop hinted cryptically at challenges to come: “There are aspects of the future which are clouded by the penetration of non-economic forces into the functioning of an industry which has always performed best in an atmosphere of economic freedom.”

Dunlop didn’t say what storm clouds specifically threatened the expansion of oil and gas. But the next “Energy and Man” speaker did. That speaker vividly described a new and unexpected threat to the industry: its vast and growing emissions of a greenhouse gas called carbon dioxide.

Depictions of global warming’s impact on human society were also starting to enter popular culture. Several years before Teller attempted to alert his New York audience, an article in Time magazine warned that CO2 building up in the atmosphere could by the early 2000s “have a violent effect on the Earth’s climate.”

One wonders: how much warning do the Liberals think the oil & gas industry needs?

Link: Disney squeezing fans too hard

NewsNation: 68% of Disney World fans say the park’s ‘lost its magic’: poll

Some of the most loyal of Disney enthusiasts say one specific thing is keeping them from visiting Walt Disney World Resort in Orlando more often — they even say it’s causing “the Happiest Place on Earth” to completely lose its magic.

It’s the cost.

A family vacation to Walt Disney World Resort is more expensive than ever and fans are noticing, according to a new poll. The gambling website time2play recently released a study based on data from 1,927 “self-described Disney World enthusiasts” about the rising costs to visit the park.

According to the study, 92.6% of those surveyed believed the cost of a Disney World vacation is out of reach for an average family. Additionally, 68.3% of people said increases made it feel like the theme park has lost all its magic.

As of Tuesday, the cost for a standard one-park day ticket on Friday, Sept. 16 is $134, though prices of tickets vary by date. Standard Walt Disney World tickets range between $139 and $154 through October, according to Disney World’s website.

When Walt Disney World Resort opened in 1971, a ticket cost only $3.50. Adjusting for inflation, that would be $22.61 today. According to Koala calculations, there has been an average price increase of 7.4% each year since the park opened.
