A year or more ago there was news of Georgia tech inventing a 3d solar cell, based on the use of nano fibers to create more surface of absorption. The tiny cell is the size of a current generation CPU.

Someone in Berkly made a solar cell based on plants and transferring their chemical energy to electricity.

then some random kid in Oregon made a "3D" solar cell that could absorb both visible and UV light.


So.... where are these on the market?

I'm surprised no one has used the 3D model and the Georgia tech model, then combining them with nanotech.

Here's that article.

I read some other articles, too, that had different ways making the cells more energy efficient. I'd like to see more cross-fertilization.

There are constant tech break throughs.. but bringing a product to market requires one main thing.. cheap and efficient.. my educated guess is if there not on the market in 4 years.. there = NEITHER.. remember solar has been around for a long time.. if it was cheap and or efficient we'd all have it buy now.. it's NOT.

I have to day this is quite true. I have articles in my office at work that are showing great advances in Solar water technologies... They were printed in the 30's!!! For a technology that is so old, it is still way to expensive to purchase for the average joe.

Well, there are alternatives to why they don't come to market.. could just be poor marketing and company management but what’s to stop a good company from buying the idea and doing it right? there is also a real consensus on global conspiracy theories.. but since these are fringe, they seem unlikely..

Without doing super accurate research I can only conclude generalities.. but my experience is reading breakthroughs does not always = market reality.. we’ve done work on tinting and block UV ray’s etc. through windows.. but you can’t find these windows at “Office Depot” and this work is at least 5-10 years old.. but for example nanotubes were created 10 years ago or more.. and a special limited hard drive available actually had nanotubes (kind of expensive to build so is my understanding) for a see through window..
