New solar cell works for 10,000 hours

Researchers engineered a solar cell that worked for 10,000 hours without its performance being compromised, according to a new study.

Why it matters: The solar energy industry has been intensely focused on perovskite solar cells that cost less to produce compared to silicon-based ones. Perovskite cells could potentially disrupt the industry but have been hampered by the fact that they can rapidly degrade with wear and tear from water and UV light.

The next step: The efficiency of the new solar cell was low — only up to 12.7%. If the stability can be achieved with previously demonstrated efficiencies for perovskite cells (upwards of 22% and on par with silicon solar cells), the price of solar energy might even compete with fossil fuels.

Biden says he'll follow CDC mask guidance: "Listen to the Faucis of the world"

Joe Biden said on ABC's "This Week" Sunday that he will follow the Centers for Disease Control and Prevention's new recommendation that people wear face coverings when they leave home to prevent the spread of the coronavirus.

Why it matters: After the White House announced the guideline last week, President Trump said he will likely not wear a mask and emphasized that the guidance was "voluntary."

Louisiana governor says state will run out of ventilators on April 9

Louisiana Gov. John Bel Edwards said on CNN's "State of the Union" Sunday that modeling projects his state will run out of ventilators for coronavirus patients on April 9 and hospital beds on April 11.

Why it matters: New York is the only state in the country with a worse per-capita death rate than Louisiana, where around 12,500 people have been infected and 409 have been killed.
