Hi! I'm Dane Carlson, and welcome to the Business Opportunities Weblog. I've been publishing this website, by myself, and sometimes with the help of others for over twelve years now. You'll notice two things about this site right away:

  • We have tons of content. In fact, since November 2011, I've published more than 26,000 posts on thousands of different business ideas and opportunities.
  • We don't sell much advertising. In late 2013, I realized that by selling advertising, what I was really selling was my readers. In 2014, I've already radically cut down on the number of ads and will hopefully keep cutting.

Cheaper solar cells will be coming soon, if new research out of Georgia Tech holds up:

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.

The technology is published in the journal Scientific Reports, the latest open-access journal from the Nature Publishing Group.

The researchers report that the organic solar cells reach a power conversion efficiency of 2.7 percent, an unprecedented figure for cells on substrates derived from renewable raw materials. The CNC substrates on which the solar cells are fabricated are optically transparent, enabling light to pass through them before being absorbed by a very thin layer of an organic semiconductor. During the recycling process, the solar cells are simply immersed in water at room temperature. Within only minutes, the CNC substrate dissolves and the solar cell can be separated easily into its major components.
