Light Can ‘heal’ Defects in New Solar Cell Materials

Posted by in categories: electronics, nanotechnology, particle physics, solar power, sustainability

A family of compounds known as perovskites, which can be made into thin films with many promising electronic and optical properties, has been a hot research topic in recent years. But although these materials could potentially be highly useful in applications such as solar cells, some limitations still hamper their efficiency and consistency.

Now, a team of researchers at MIT and elsewhere say they have made significant inroads toward understanding a process for improving perovskites’ performance, by modifying the material using intense light. The new findings are being reported in the journal Nature Communications, in a paper by Samuel Stranks, a researcher at MIT; Vladimir Bulovic, the Fariborz Maseeh (1990) Professor of Emerging Technology and associate dean for innovation; and eight colleagues at other institutions in the U.S. and the U.K. The work is part of a major research effort on perovskite materials being led by Stranks, within MIT’s Organic and Nanostructured Electronics Laboratory.

Tiny defects in perovskite’s crystalline structure can hamper the conversion of light into electricity in a solar cell, but “what we’re finding is that there are some defects that can be healed under light,” says Stranks, who is a Marie Curie Fellow jointly at MIT and Cambridge University in the U.K. The tiny defects, called traps, can cause electrons to recombine with atoms before the electrons can reach a place in the crystal where their motion can be harnessed.

31 responses to “Neverending Sex”

Posted by in categories: biotech/medical, life extension, sex

Let’s formulate the task of life extension slightly differently. Something like this…How can we extend sex appeal?

Gyms and beauty salons are in charge of this question now. There is some success, but it’s mostly superficial. Plastic surgery only masks, but doesn’t delay the processes of aging.

Expanding sex appeal is a complex task. Its aspects include both beauty and the activity of the brain. To be sexually attractive we have to be smart and fun. One cannot solve the problem of dementia with makeup.

Corrected: U.S. sees first case of bacteria resistant to last-resort antibiotic

Posted by in categories: biotech/medical, health

By ransdell pierson and bill berkrot.

(Reuters) — U.S. health officials on Thursday reported the first case in the country of a patient with an infection resistant to a last-resort antibiotic, and expressed grave concern that the superbug could pose serious danger for routine infections if it spreads.

“We risk being in a post-antibiotic world,” said Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, referring to the urinary tract infection of a 49-year-old Pennsylvania woman who had not traveled within the prior five months.

Archaeologists think they’ve found Aristotle’s tomb

Posted by in category: futurism

Nearly 2,400 years after his death, archaeologists believe they’ve finally found the tomb of Aristotle. Researchers made the discovery during a 20-year dig in the ancient Greek city of Stagira, reports Atlas Obscura.

Aristotle was born there in 384 BC, but he died in a different city, Chalcis, about 50 miles north of Athens. Literary sources mention that Aristotle’s remains were moved to Stagira after his death, but his burial site has been a topic of debate for many years, the International Business Times reports.

The tomb in Stagira believed to be the philosopher’s is a 32-foot-tall dome with a marble floor and views of the entire city. “The thing is, the archaeologist data is in fine accordance with historical sources,” archaeologist Konstantinos Sismanidis tells CNN.

The Future of Humanity’s Food Supply Is in the Hands of AI

Perhaps it’s serendipitous, then, that the machines have finally arrived. Truly smart, truly impressive robots and machine learning algorithms that may help usher in a new Green Revolution to keep humans fed on an increasingly mercurial planet. Think satellites that automatically detect drought patterns, tractors that eyeball plants and kill the sick ones, and an AI-powered smartphone app that can tell a farmer what disease has crippled their crop.

Forget scarecrows. The future of agriculture is in the hands of the machines.

Fujitsu is Making a Robot to Judge Tokyo’s 2020 Olympics

Posted by in category: robotics/AI

Fujitsu is building a robot that uses 3D laser sensors to detect motion without the need for athletes to wear any special suits. The robot will be ready for the Olympics in 2020 in Japan, and will precisely score gymnasts based on measurements taken by the sensors.

Japan is making sure the 2020 Olympics will be a technological festivity. They even may be spending a staggering $8.1 million for an artificial meteor shower.

In addition to the “fireworks,” Fujitsu, in partnership with the Japan Gymnastics Association, is developing the ultimate judge to end all biases in the Olympics: a robot programmed to precisely score gymnasts at the Olympics with absolute fairness by using 3D laser sensors capable of measuring 76,800 points of motion per frame up to 30 times per second.
