Nanotechnology Meets Solar Power

New methods of creating solar cells cut manufacturing costs nearly in half. The New Jersey-based company is also working to create super-efficient cells by using nanotechnology.

What's the Latest Development?


A new low-energy method of making solar cells could cut the manufacturing costs nearly in half, making them far more efficient or cheaper than conventional cells. Rather than the high-temperature gas-based process currently used by most manufacturers, the new technique "deposits coatings in a low-temperature, liquid-based process." The technology, developed at Rice University, is being commercialized by a New Jersey start up which estimates it can save $1 million annually on electricity costs using the low-temperature method.  

What's the Big Idea?

The New Jersey company, Natcore Technology, is also working to incorporate nanotechnology into the solar cell industry. One of the designs for a next-generation solar panel involves depositing 'quantum dots' on silicon solar cells. "The quantum dots are designed to absorb colors that silicon doesn't, potentially doubling the efficiency of solar cells." Natcore is also working with Kodak to develop a process that coats carbon nanotubes with a solar semiconductor material to produce thin, flexible solar cells.

Why the ocean you know and love won’t exist in 50 years

Can sensitive coral reefs survive another human generation?

Videos
  • Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
  • The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
  • If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.

Why modern men are losing their testosterone

Research has shown that men today have less testosterone than they used to. What's happening?

  • Several studies have confirmed that testosterone counts in men are lower than what they used to be just a few decades ago.
  • While most men still have perfectly healthy testosterone levels, its reduction puts men at risk for many negative health outcomes.
  • The cause of this drop in testosterone isn't entirely clear, but evidence suggests that it is a multifaceted result of modern, industrialized life.

  • The United States health care system has much room for improvement, and big tech may be laying the foundation for those improvements.
  • Technological progress in medicine is coming from two fronts: medical technology and information technology.
  • As information technology develops, patients will become active participants in their health care, and value-based care may become a reality.
