Nanosolar Price Barrier Breakthrough Makes Solar Electricity Cheaper Than Coal

[Guest apolo1512]

A new combination of nano and solar technology has made it possible for solar electric generation to be cheaper than burning coal. Nanosolar, Inc. has developed a way to produce a type of ink that absorbs solar radiation and converts into electric current. Photovoltaic (PV) sheets are produced by a machine similar to a printing press, which rolls out the PV ink onto sheets approximately the width of aluminum foil. These PV sheets can be produced at a rate of hundreds of feet per minute.

 

"It's 100 times thinner than existing solar panels, and we can deposit the semiconductors 100 times faster," said Nanosolar's cofounder and chief executive officer, R. Martin Roscheisen. "It's a combination that drives down costs dramatically."

 

Because of their light weight and flexibility, the PV sheets (dubbed PowerSheets) are much more versatile than current PV panels, which must be mounted on sturdy surfaces like roofs or the ground. In addition, because there is no silicon used in the production of the sheets, they cost only 30 cents per watt of power produced.

 

Traditional PV cells cost approximately $3 per watt, while burning coal costs about $1 per watt.

 

"This is the first time that we can actually drop the cost of solar electricity down to a level that would be competitive with grid electricity in most industrialized nations," said Nanosolar co-founder Brian Sager.

 

Nanosolar is ramping up production of its PowerSheets at factories in San Jose, California, and Berlin, and expects to have them commercially available before the end of the year. The buzz around the PowerSheets is so strong that the company already has a three to five year backorder, and the company has raised more than $150 million from venture capitalists, including Google cofounders Larry Page and Sergey Brin.

 

"Solar panels have not been very popular to the American people because they've been too expensive. That's what we're changing now," Roscheisen said.

I wonder how efficient and durable it is though?

It would be nice to see this get used though.

 

Hopefully it doesn't use any hazardous or limited materials in production.

That is no news at all.

 

Nanosolar has been producing its inky film cells for several years now. The last time I checked 3? years ago, if someone across the street from their offices wants too buy the product; they will not sell to anyone as they contracted full production with Germany.

 

Check their web site and youtube showing the machinery.

 

So even local californians have to buy chinese or other sources at the higher price. What good is in it ?

The city I live in was considering to implement some solar panels and they did not know that existing lower costs are there but unreachable to even locals.

 

The 'wonderful' corporate world and their tricks. Inventing something good you cannot use.

 

An announcement from today, some development success in solar cells that convert solar light and heat (that up to now is detrimental) to electricity, increasing efficiency.
