F01.00001: The Future of CdTe Solar Photovoltaics Invited Speaker: Markus Gloeckler Solar photovoltaic (PV) energy is a rapidly growing industry and is soon to become the leading contributor for new energy capacity additions in several markets, including the United States. First Solar manufactures thin-film CdTe PV modules and is currently ramping the new utility-power optimized Series 6 technology. Series 6 modules will have initial power up to 440 Watts with an optimized design to lower installation and other balance of system cost. Series 6 enables to take full advantage of high throughput low cost processing of semiconductor materials on glass substrates, compared to the market dominating technologies utilizing wafered crystalline silicon. First Solar’s thin-film CdTe solar cells have been certified at 22% cell efficiency, which means it has achieved approximately 70% of its ultimate entitlement that is defined by the Shockley-Queisser limit for single-junction solar cells. Fundamental work has demonstrated that the defect chemistry, in particular doping efficiency of the p-type semiconductor provides opportunities for future improvement. |

F01.00002: Journey to the Center of a Neutron Star: From Astrophysical Observations to the Neutron Star Equation of State Invited Speaker: Carolyn Raithel Neutron stars are among the densest objects in the universe. As such, they provide a unique laboratory for studying the behavior of matter when pushed to the extreme. In this talk, I will discuss the various ways that astronomers are using neutron stars to probe the so-called equation of state. In particular, I will briefly review the latest in mass and radius measurements of neutron stars. I will then present a mapping that we have developed to infer the interior structure of the star from these types of observations. Finally, I will discuss what we have learned from the first detection of gravitational waves from a neutron star merger and what we hope to learn from future detections. |
