NSAC trip: Visit to Fermilab - Saturday, December 7th (RSVP required)
by NSAC 26 Nov '13

26 Nov '13

Dear BRK grad students, NSAC would like to invite you to a tour of Fermilab (Fermi National Accelerator Laboratory, near Chicago, IL) on* Saturday December 7th, 2013*. Fermilab (http://www.fnal.gov/) is a US Department of Energy national laboratory specializing in high-energy particle physics with a mission to inspire the world and enable its scientists to solve the mysteries of matter, energy, space and time for the benefit of all. We are registered as a group and* limited to 20 people*. We will be leaving at 8 a.m.and expect to return to Purdue that evening (exact time depends on individual drivers). The tour lasts about two hours. We will view the Laboratory from the 15th floor windows and visit various displays located there. The tour moves to the Linear Accelerator building where we will see the Cockcroft-Walton, the components in the linear accelerator gallery and the Main Control Room. A detailed agenda for the day will be emailed later to all attendees. If you are interested in going, please *RSVP at the following link by November 25th*; availability is on a first-come, first-served basis (limit 20 people). https://docs.google.com/forms/d/1lF4pj86-atijpHLqXo5-_GlFt7ipxXoWDkH53ApO3k… Further information regarding transportation will be sent later. Email nsac(a)purdue.eduif you have any questions/comments.

Fwd: [Reminder] Final Exam Announcement - Nov. 21, 3 PM, BRK 1001
by John Wilcox 21 Nov '13

21 Nov '13

Scheduling of Examinations: Student’s Name: John Wilcox Examination Date: 11-21-2013 Examination Time: 3:00 PM Building & Room: BRK 1001 Thesis Title: Solar Cell Temperature Dependent Efficiency and Very High Temperature Efficiency Limits Abstract: Clean renewable solar energy is and will continue to be an important source of electrical energy. Solar energy has the potential of meeting all of the world’s energy needs, and has seen substantial growth in recent years. Solar cells can convert sun light directly into electrical energy, and much progress has been made in making them less expensive and more efficient. Solar cells are often characterized and modeled at 25 °C, which is significantly lower than their peak operating temperature. In some thermal concentrating systems, solar cells operate above 300 °C. Since increasing the temperature drastically affects the terminal characteristics, it is important to quantify the losses caused by raising the temperature. Methodologies for including the temperature dependent material parameters in analytical and detailed numerical models have be examined. The analytical model has been developed to analyze Shockley-Queisser detailed balance limit, as well as the Auger, Radiative and SHR recombination limiting cases from 25 °C to 800 °C, at 1x, 500x and 2000x suns concentrations. The results of this analysis show that the efficiency of a direct bandgap material with an optimal bandgap could reach 19 % at 400 °C and 2000x suns, if the SHR recombination is reduced to an acceptable level. An analytical solar cell model was also used in a quasi-3D numerical model to simulate the temperature dependent resistivity losses. It was found that the resistive losses can double when the temperature of a solar cell increases from 25 °C to 100 °C. This will cause the conversion efficiency temperature coefficient to deteriorate by 10%. By using the temperature dependent material parameters for Si in a detailed numerical model, it was found that some of the adjustable parameters, increase the conversion efficiency temperature coefficient and the Voc, while other parameters would only increase the Voc. This conclusion can be used by solar cell manufactures to improve the solar cell parameters with the biggest possible gain. -- John Wilcox jrwilcox(a)purdue.edu Purdue University School of Electrical and Computer Engineering
