Installed Price of Solar Photovoltaic Systems in the U.S. Continues to Decline at a Rapid Pace

August 12, 2013

The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2012 and through the first half of 2013, according to the latest edition of Tracking the Sun, an annual PV cost tracking report produced by Berkeley Lab.

Artificial Forest for Solar Water-Splitting

May 16, 2013

Berkeley Lab researchers have created the first fully integrated artificial photosynthesis nanosystem. While “artificial leaf” is the popular term for such a system, the key to this success was an “artificial forest.”

Good Cats Wear Black: Black Nanoparticles Could Play Key Role in Clean Energy Photocatalysis

April 10, 2013

Disorder engineering turns low-efficiency photocatalytic “white” nanoparticles of titanium dioxide into high-efficiency “black” nanoparticles and could be a key to hydrogen energy.

One Step Closer to Hydrogen Production from Photoelectrochemical Water-Splitting

January 15, 2013

In the quest to produce an environmentally benign renewable fuel, scientists have explored many techniques to split water molecules to produce hydrogen. Still, the current photovoltaic designs are not yet technically or economically viable. Materials research in this area has been promising, but research on the engineering design of these photoelectrochemical systems has been [...]

New Path to More Efficient Organic Solar Cells Uncovered at Berkeley Lab’s Advanced Light Source

January 7, 2013

Working at Berkeley Lab’s Advanced Light Source (ALS), an international team of scientists found that for highly efficient polymer/organic solar cells, size matters. Impure domains if made sufficiently small can lead to improved performances in polymer-based organic photovoltaics.

The Installed Price of Solar Photovoltaic Systems in the U.S. Continues to Decline at a Rapid Pace

November 27, 2012

The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by Berkeley Lab’s Environmental Energy Technologies Division. Recent installed price reductions are attributable, in large part, to dramatic reductions in PV module prices, which have been falling precipitously since 2008.

Berkeley Lab Breaks Ground on New Solar Energy Research Facility

October 19, 2012

Berkeley Lab has broken ground on its Solar Energy Research Center (SERC). The three-story structure will be nearly 40,000 sq. ft. in size and will house approximately 75 people when completed. SERC will hold the labs and offices of the Joint Center for Artificial Photosynthesis whose goal is to one day develop a solar fuel generator.

Photovoltaics from Any Semiconductor

July 26, 2012

Berkeley Lab researchers have developed a technology that enables low-cost, high efficiency solar cells to be made from virtually any semiconductor material. This opens the door to the use of plentiful, relatively inexpensive semiconductors previously considered unsuitable for photovoltaics.

Berkeley Lab Research Sparks Record-Breaking Solar Cell Performances

November 7, 2011

Theoretical research by Berkeley Lab scientists has led to record-breaking efficiencies in solar cells. The research showed that, contrary to conventional scientific wisdom, the key to solar cell efficiency is not absorbing more photons but emitting more photons.

Installed Cost of Solar Photovoltaic Systems in the U.S. Declined Significantly in 2010 and 2011

September 15, 2011

The installed cost of solar photovoltaic (PV) power systems in the United States fell substantially in 2010 and into the first half of 2011, according to the latest edition of an annual PV cost tracking report released by Berkeley Lab.
