Swedish and Chinese scientists have developed a new kind of organic solar cell that has been optimized to convert ambient indoor light into electricity.

The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.

As the internet of things expands, it is expected that we will need to have millions of products online, both in public spaces and in homes. Many of these will be the multitude of sensors to detect and measure moisture, particle concentrations, temperature and other parameters. For this reason, the demand for small and cheap sources of renewable energy is increasing rapidly, in order to reduce the need for frequent and expensive battery replacements.

This is where organic solar cells come in. Not only are they flexible, cheap to manufacture and suitable to manufacture as large surfaces in a printing press, they have one further advantage: the light-absorbing layer consists of a mixture of donor and acceptor materials, which gives considerable flexibility in tuning the solar cells such that they are optimized for different spectra—for light of different wavelengths.

Researchers in Beijing and Linköping, led by Jianhui Hou and Feng Gao, have now developed a new combination of donor and acceptor materials, with a carefully determined composition, to be used as the active layer in an organic solar cell. The combination absorbs exactly the wavelengths of light that surround us in our living rooms, at the library and in the supermarket.

I'm not sure that the author of that article has quite got the grasp of the concept of "renewable" energy sources...

What these new developments in the article are actually accomplishing here is the catching/trapping of energy that is otherwise 'wasted' in the form of light and heat, and effectively reusing/recycling that energy to repower low-power use appliances --  it could possibly also recharge phones, tablets and laptops, with a battery as an intermediate power store..

As such, this particular innovation isn't reliable on "renewable" energy sources --  but rather is a means of power saving, via using otherwise "wasted" energies.

I agree.  Years ago it was established that there was no such thing as a perpetual motion machine.  One can't renew the energy.

What this is doing is making more efficient use of the energy as it passes through our lives...which is pretty good, as well.

Cool

And you need to get an education...

Instead of so lavishly lapping up your 'Cato Institute' bullshit and fantasies..

I was thinking the same about you and didge. He's kissing your ass in the deep place, tryin' to groom you for his buddy. He's feelin' a bit insecure and needs your strong back, and weak mind, to support him.

Nah, we dont get along like you two. It would never work between Didge and I.

You two have something special going on. Dont waste this chance for happiness.

Wow so I post an article and make no futher comments and Quill is yet again obsessed and paranoid with me.

I guess he is clearly feeling insecure since I stopped engaging him in debate,. Mainly as he acts like a baby.

Cool

Could make it a '3D' style target...

And you, Fred & co. can all shoot at it together..
