Not exact matches

With this technique, the Empa team has again been able to significantly increase the energy conversion efficiency from sunlight into electricity using CIGS thin film solar cells on flexible plastic foils — to a new record level of 20.4 %, representing a marked improvement over the previous record of 18.7 % established by the same team in May 2011.

Unger concludes: «They can lead to a coarse over or underestimation of the power conversion efficiency.»

By dramatically improving the speed and efficiency of conversion over conventional approaches, these enzymes could stimulate efforts to grow crops for fuel, with implications for biodiversity in the form of increased land use for this purpose, potential shifts away from fossil fuel use and reductions in greenhouse gas emissions.

A new solar cell design could raise the energy conversion efficiency to over 50 % by absorbing the spectral components of longer wavelengths that are usually lost during transmission through the cell.

«New solar cell design could pave the way for over 50 % energy - conversion efficiency.»

We measure incident photon - to - current efficiency (IPCE) to get a wavelength - dependent conversion efficiency that can be integrated over a reference spectrum (AM1.5 G) to corroborate the photocurrents obtained under broadband illumination.

Said Nicole Passage, Managing Editor of Open Road, «Prior to the past year, we outsourced almost all eBook conversion, but recently we've begun to adopt internal solutions, allowing us to increase both efficiency and control over results.»

By switching to LED lighting technology and implementing energy - saving measures and conversions, the LEA Live Entertainment Award Committee and the Production Resource Group have already achieved significant improvements in energy efficiency over the past few years.

Today's silicon crystal solar panels are a dramatic improvement over the original Bell Lab designs, with some cells achieving a conversion efficiency of about 35 %, but the power output is still intermittent and load factors are very low, around 15 %.

Even allowing for improved energy efficiency, if global energy demand continues to grow along the anticipated trajectory, by 2030 the investment over this period in energy - carrier and - conversion systems will be over 20 trillion (1012) US$, being around 10 % of world total investment or 1 % of cumulative global GDP (IEA, 2006b).
