From 31% to 44% doesn't seem to be double to me, but increasing efficiency and reducing cost is very much needed for solar energy. I'm glad this research in going on and hope it continues.

yeah, i think plastic and organic are major ways to reduce cost. Silicon processing is a major hurdle for the introduction of PV solar cells.

present is 36% efficiency. the new research here is for 44%. By about 8%. This the next major step towards higher efficiency. Low cost also. Coommercialisation will be fruitfull. So by 5 more years we reach about 60 to 70% efficiency.I forsee a great solar future in our earth planet.

Lower cost with double the efficiency!! This seems to be first one of the breakthrough discoveries that is very much needed to take the solar power generation to the next milestone. Is there a plan to build a solar panel to demonstrate the efficiency that could be derived once it is produced commercially?

Let's hope this one is really a breakthrough that can be economically employed. That could give a real boost to this sector of the industry and, ultimately, to the consumer.

Let us see - in this sector, we have always had this nice expectation only to be disappointed. But this one could be real.

Sharp shows 35.8% efficiency. Even getting to 50% would be a big plus. Is there a good chart showing efficiency growth over time anyone knows of?

this is pretty cool discovery. If a commercial viability can be found then it can be a game changer for the solar cells. Article worth forwarding to clean energy enthusiasts.

It is unexpected discoveries like these that offer the potential for cost effective solar power generation - and can render the currently leading technology obsolete overnight. A scary place to be investing but an exciting time for the future of affordable distributed power generation.

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.
