New Solar Panels: 80% Efficient

black solar panels New Solar Panels: 80% EfficientA team of scientists from the Rensselaer Polytechnic Institute has been developing a brand new solar energy technology that is about to revolutionize the way we collect and distribute solar energy. Rows, or stacks, of pivoting lenses built into a glass building facade track the movement of the sun across the sky, focusing its rays onto high-tech solar cells.

The new system uses high-tech solar-concentrator technology and advanced materials. The full-size prototype will be incorporated into a new building at The Center of Excellence in Syracuse, New York.

The key breakthrough of the invention is the miniaturized concentrator solar cell, which uses a lens with concentric grooves to focus the collected light. The lens is only the size of a postal stamp, while the current solar panel sizes are 4×4 feet. They also say that the new solar cell concentrator uses both the light and the heat concentrated from the Sun’s energy.

Some microchannels posed at the base of the module transfer the heat energy and the light to wires contained inside. Each vertical stack of lenses rolls and tilts like a track blind, keeping the lenses’ surface faced to incoming sunlight as the sun changes its position on the sky throughout the day.

Incorporating these new cells into arrays could make solar energy an option that is competitive with other energy sources, reducing our dependency on fossil fuels. The efficiency of these solar panels is said to be around 80%, compared to 14% of those existing today.

But like all such amazing technology jumps.. it never sees the light of day commercially.  How is that?

@Matt I know, here we are, five years later, and we don't have an 80%-efficient solar panel commercially-available. lab experiments are one thing, but expensive materials or complicated manufacturing can kill the product before the market even gets a taste of it.

i mean, why do we have DVD and not LaserDisc today? DVD's more portable. why do we have 9% solar panels today? because they're cheap. :/ I mean, how complicated is the fresnel-blind setup in this post? add control circuits and bam, too complicated for ordinary man.

80% efficient solar panels means too much efficient. kindly clarify whether it is for heating Or for electric generation

Claiming 80 % efficiency when using both for electricity and heat generation is vague. Do you mean 5% electricity plus 75 % heat? Please be more specific / realistic.

When will I be able to buy my own 80% efficient solar panels in a nice role-able durable backpack friendly energy gathering device?
