‘Oscar Madison’ approach to solar cells may outshine ‘Felix Unger’ design

In the race to enhance the efficiency of solar cells, spending the time and effort to get tiny nanowires to line up neatly on the top of ordinary silicon wafers may not be worth the effort. An international team of researchers has for the first time demonstrated that random, haphazardly grown silicon nanowires can significantly boost the power-producing capabilities of solar cells by trapping a broad spectrum of light waves and capturing sunlight streaming in from a wide variety of angles. The nanowires, which are wrapped in a shell of silicon oxide, serve as an antireflective coating on top of the usually shiny silicon wafer. The scraggly tangle captures light ranging in color from red to violet, and the random orientation of the wires means the coating would continue to absorb light even as the angle of the Sun changes throughout the day. The researchers fabricated the jumbled, yet effective, antireflective coating by vaporizing silicon powder and then depositing it on top of a silicon wafer. The process, described in the AIP’s new journal AIP Advances, is relatively inexpensive and could be scaled up for large manufacturing operations. For future work the team plans to create structures that are more ordered to test if the messy arrangement really is better.

Article: “Graded index and randomly oriented core-shell silicon nanowires for broadband and wide angle antireflection” is published in AIP Advances.

1. The new solar cells also work better...

...if bury them in piles old dirty socks.

2. Can't tell if you're being funny, sarcastic or derisive.

:shrug:

3. Did you ever watch "The Odd Couple"?

I was just pushing things a bit more in the Oscar direction.

4. It’s an alusion to the “Odd Couple” characters referred to in the OP

6. Thanks!

It flew right over my head.

8. It's been so long since I saw the movie

Most of my memories (and even those are dim) are from the TV show.

I can't remember if the movie had any scenes of Oscar's disaster-area bedroom, something that cropped up fairly often on the TV show. It was the first image that popped into my mind when I saw the OP.

9. The movie is based on the play (of course)

I don’t recall a sock-strewn bedroom.

10. Do they use Pizza crumbs as a Catalyst?

Some things are just too 'Elegant' for their own good.

7. As in most aspects of life, it usually does.
