Demonstration of a 33% efficient Cassegrainian Solar Module

by JX Crystals  (Aug. 28, 2014)

Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar ...

Welcome to Net-Zero

by ASTM International  (Aug. 29, 2014)

For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with cutting-edge renewable energy tools, have made the concept of a net-zero energy use home anything more than a ...

Test Sites And Testing of 3-Sun Mirror Modules

by JX Crystals  (Aug. 28, 2014)

ABSTRACT The demand for solar photovoltaic cells and modules has far outstripped PV cell supply and module prices are rising. To solve this problem. JX Crystals is developing a 3-sun mirror module that uses 1/3 the cell area to triple module production at a lower cost. Our concentrator module design uses existing planar cells. We simply cut ...

Solar PV Carousel Trackers for Building Flat Rooftops

by JX Crystals  (Aug. 28, 2014)

ABSTRACT Herein, a SunTrack Carousel tracker is described for mounting on residential or commercial building flat rooftops in order to produce more k\Vh per kW relative to fixed PV modules. The JX Crystals (JXC) fixed-tilt / azimuth carousel is a low profile tracker designed to distribute weight evenly over a large area and for low wind resistance ...

Start-up of first 100 kw system in Shanghai with 3-sun PV Mirror modules

by JX Crystals  (Aug. 28, 2014)

ABSTRACT Thanks to funding from the Shanghai City government, Shanghai Import Export Trading Company, and Shanghai Flower Port, we have designed and fabricated in pilot production the first 3-sun 180 W (STC) mirror panels. Three of these panels were first tested in the US showing calibrated PTC ratings of 150 W. Then 24 panels were installed on ...

Solar`s Time to Rise and Shine.

by Ensia  (May 27, 2014)

Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond ...

Near Term Lower Cost Solar Electric Power for US Commercial Customers

by JX Crystals  (Aug. 28, 2014)

Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the ...

Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review

by European Commission, Environment DG  (Jul. 2, 2014)

What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products ...

China’s Solar Panel Production to Double by 2017

by Earth Policy Institute  (Jul. 8, 2014)

China installed a world record amount of solar photovoltaics (PV) capacity in 2013. While this was the first time the country was the number one installer, China has led all countries in making PV for the better part of a decade. China now accounts for 64 percent of global solar panel ...

Economic Potential for Thermophotovoltaic Electric Power Generation in the Steel Industry

by JX Crystals  (Aug. 28, 2014)

ABSTRACT - A steel mill extrudes steel billets at temperatures above 1400 °C continuously 24 hours a day. The steel billets then go to cooling beds where they slowly cool down to below 1100 °C. JX Crystals Inc makes Gallium Antimonide (GaSb) thermophotoyoltaic (TPV) cells that can generate over 1 W/cm when exposed to infrared radiant ...
