First Solar (FSLR) Hits Record High 18.6% Solar Module Efficiency – Stocks in the News – Yahoo Finance
Now they are shipped via express mail in plastic box[es]. On the other hand, organic solar cells havent displaced crystalline silicon cells, either, and it is still not clear if a low cost organic module can be made that will survive the qualification test, a rigorous ordeal that subjects prototypes to swings in temperature and high humidity. The most effective application could be combining perovskites with silicon to create a multijunction cell. The most tantalizingly efficient prototypes on the NRELs chart are multijunction cells, since a combination of materials captures a wider spectrum of sunlight. A team at Stanford has increased a low-quality silicon cells pitiable 11.4% efficiency to 17% an almost 50% boostby combining it with 12.7% efficient perovskites. But Michael McGehee, co-author of the study, echoed the usual caveat: We have a ways to go to show that perovskite solar cells are stable enough to last 25 years. The Bottom Line Silicon remains the market leader in photovoltaic systems, and for good reason.

Solar Space Race Already Underway – Yahoo Finance
There are many challenges to solve, including: wireless power transmission, space transportation, construction of large structures in orbit, satellite attitude and orbit control, power generation, and power management. According to the IEEE , wireless power transmission, where JAXA is focused, is the most daunting challenge to solve. NASA is working on very efficient, and very aesthetically pleasing flower-shaped, solar collectors that will beam microwaves to earth. NASA proposes to develop its Solar Power Satellite via Arbitrarily Large Phased Array (SPS-ALPHA) through four generations of prototypes with final launch in 2025. View photo . Its Expensive None of this will be cheap. The first space based solar system could top $20 billion.

The results from this world record indicate that First Solars panels now can convert more sunlight into electricity than the average silicon panel. First Solars CdTe thin film is now rightly categorized as a high performance product, said Raffi Garabedian, First Solars Chief Technology Officer. At one time, we might have been characterized as a low cost, low efficiency technology, but consistent with our technology projections we are now proving that CdTe thin film delivers both industry-leading performance AND sustainable thin-film cost structures. Garabedian continued by emphasizing First Solars significant sustained investment in the development of CdTe technology/ He said, While silicon technologies have approached their theoretical efficiency entitlement and leveled out in terms of performance and cost, First Solar continues to harvest the upside available from its superior thin film technology. Our CdTe modules are now more efficient than the best multi-crystalline Si modules, and we still have a great deal of technology head room for further innovation. According to the companys press release , Nick Strevel, First Solars Senior Manager of Technology, commented on the performance of the technology. He noted that efficiency combined with other real-world performance attributes result in First Solar technology delivering higher energy density than multi-crystalline Silicon (m-Si) solar panels. Given the same installed nameplate module capacity (Watts) with equivalent ground coverage ratio, Solars CdTe product will provide up to 8 percent more useable energy from the same land area than m-Si, which gives First Solar a competitive advantage over other PV technologies. At the close of trading, FSLR finished the day up just less than $3/share, roughly 5.9% on the day, so clearly investors are fans of this milestone for First Solar.
