DARPA Awards $53 Million for Solar Power Research

mygadgetbox writes "Defense Advanced Research Projects Agency (DARPA) will be giving a consortium led by the University of Delaware nearly $53 million in funding to more than double the efficiency of terrestrial solar cells within the next 50 months. DARPA wants the consortium to develop and produce 1,000 Very High Efficiency Solar Cell (VHESC) prototypes that are affordable and that operate at efficiencies of at least 50 percent. The goal is to create solar cells that operate at about 54 percent efficiency in the laboratory and 50 percent in production."

Meh.

We spent two decades wasting time trying to improve the energy efficiency of solar cells. The energy efficiency isn't what matters - it is the cost efficiency! If you are using solar cells as supplemental power to a house (their most effective application), then doubling the energy efficiency of the panel just means you get to use a smaller panel. Who cares - you have a whole roof's worth of space up there. Whereas if you get the price down, then you will decrease the amount of time it takes to pay off the cost of the cells, making it worthwhile to include them in more homes. And for other uses - cars, power plants, even if we had 50% efficient cells they still wouldn't generate enough power to be much use.

I have been getting excited about some of the recent research that is making progress towards less costly, cleaner (to produce and dispose) solar cells. I guess if you are the military, and price is not an issue than this DARPA research is usefull. They need to find some way to power all this new electronics equipment that soldiers are carrying. But it is improvements in cost efficiency that will really make a difference in real world.

1000000 times better...

...than looking for ways to bury waste products in the ocean.

Photocells are already fantastic technology. Not only do you save the energy you would otherwise be drawing from a power plant, you also save the energy needed to deliver the energy to the point where it is used.

A lot of public lighting near my home is now solar powered. The big advantage is that you don't have to dig trenches to the site. Trenching is very expensive because of the associated labour costs, and labour costs feed back directly into energy costs.

While I agree sometimes it is better to spend the money and get more efficient, I'm not sure I want my tax dollars wasted on something like this if the govt decides to buy a single expensive solar cell rather than some body armor for some troops on the ground facing suicide bombers...

Body armour may stop shrapnel. Body armour can't stop kenetic force. So it's good versus grenades, small arms, peripheral range of explosions, but piss poor against a bomb attack.

Have you ever thought that if the government didn't spend so much money sending troops to other countries where they are not wanted, there would be plenty of money to spend on good research such as this?

Nah, you have it backwards... if the American people weren't kept in a constant state of fear and reliance on the Pentagon to "protect" them, they wouldn't be so willing to fork over their tax dollars to support the world's largest military. That's the beauty of the system: the bigger the US military-industrial complex grows, the more the rest of the world resents and fears the USA. The more the rest of the world hates and fears the USA, the more insecure the US population becomes. The more insecure the US population becomes, the more willing they are to funnel more of their tax money into "defense", in the hopes that it will make them safer from the world that hates them so. So essentially the more money they spend, the more money they will have to spend later on.
