10% is low compared to the claim posted in another article. http://www.eetimes.com/electronics-news/4207381/IMEC-reports-solar-cells I am wondering whether SunPower's claim is true or not. Any comment?

"500 grams per square meter, instead of today's customary 20-kg per square meter for silicon-based solar cells", what would be the cost differential? Any clues?

Lab numbers are : 2009 : 6.1% April 2010 : 7.7% and they claim to target 10+% No products until 2012, so still lab-level tech, but those numbers/trends are quite good. Of course, they are not the only roll-roll Solar PV solution, and lifetimes/degradations are only hinted at.

In terms of weight, organic solar cell looks like an attractive product. Does anyone know the efficiency of it compared to that of inorganic solar cell?

Organic, solar, what's not to like! Anyone knows any details of this technology to judge how sounds it is? Kris

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
