Solar cells typically operate at temperatures below 100 °C. A new class of 'refractory' solar cells was presented at the 43rd IEEE Photovoltaic Specialist Conference in June 2016. These new cells are stable at tempertures over 600 °C.

In addition to applications in CSP-CPV hybrid plants, these cells open up new application areas for solar cells. Those applications include  power beaming for wireless recharging of electric UAV’s, high temperature cells for space probes to Venus and Mercury, and deployment in nuclear-photovoltaic hybrids.

The Tecnológico de Monterrey came to the QESST for a two day intensive session on the use and operation of photovoltaic devices.The majority of the students were enrolled in the Architecture schools at Tecnológico de Monterrey in Mexico and were exposed to the more engineering side of photovoltaics. The students each fabricated a solar cell module and then used the module in outdoor testing. As photovoltaics is an international technology the Solar Power Labs was pleased to be able to host the Mexican students and looks forward to further collaborations in the future.

Twelve students just finished the latest course on the manufacture of solar cells at ASU. At the completion of the course the students were able to complete the manufacture of high efficiency solar cells on the pilot line at the solar power labs. Half the students came from across the US as part of the QESST engineering research center, and the other half were from the SUN IGERT program at ASU.

Solar Power Laboratory director Professor Christiana Honsberg wins the 2015 William R. Cherry Award. It will be presented at the 2015 Photovoltaic Specialists Conference in New Orleans on June 15 2015

Dr. Christiana Honsberg, Distinguished Professor of Electrical Engineering and Director of the Solar Power Laboratory at the Arizona State University, will be receiving the Cherry Award in recognition for her multiple contributions to the advancement of photovoltaics. Her notable contributions include the pioneering of advanced PV concepts ranging from the development of a generalized thermodynamic theory for determining efficiency limits of solar cells to making seminal advances in the understanding of intermediate band, interband and quantum well approaches.

Each summer we run a research program for participants to learn about solar cell manufacturing and to conduct research on improving solar cell performance. After going through basic training on how to make a silicon solar cell, the larger group splits into teams to research a special topic on solar cells.

This year the program has significantly expanded from previous years. We now have 24 participants taking the program under the guidance of five graduate student mentors. We have also extended to the time that people work on the projects to eight weeks.

Solar power is booming and we use the summer program to educate on the technology behind the solar cell.  To reflect the broad use and impact of solar power in the community,  the program is a very inclusive environment and participants come from a range of back grounds and varied educational levels. Young Scholars from high schools get their first taste of what it is like to do research in a university cleanroom. The majority of the program consists of undergraduate students from both community colleges and universities. These students get to explore new concepts in solar cells design an fabrications. We also have STEM teachers who take what they learn over the summer back to their classrooms. At the graduate level, students who have been studying the device physics of photovoltaics have the opportunity to make a solar cell on a pilot production line and explore the issues and challenges involved in taking a new technology from a lab and into commercial production.

Its time one again for the annual SPL/QESST thanksgiving feast. This year we will be frying up four turkeys and serving them to the hungry hordes. If you are associated with QESST or SPL you should have an email invitation.

The lunch will be held in the courtyard at the Solar Power Lab @ MTW on Wednesday, November 19th, 2014 at Noon.

Bring food if you like but we have four turkeys so no one will go hungry.

Seminar: Present and Future of Photovoltaics

Dr. Stuart Bowden
Director of Solar Power Laboratory
School of Electrical, Computing and Energy Engineering
Arizona State University
Tempe, Arizona
The photovoltaic industry has grown at over 30% per annum for the last two decades with present sales of $100 billion per year. As a quantum energy converter, photovoltaics has the potential to revolutionize electricity production in much the same way that solid state physics has changed industries from computing and lighting. The presentation will discuss the present state of the photovoltaic industry and why crystalline silicon continues to be the dominant technology in solar cell production. This presentation will cover all aspects of production in crystalline silicon from the present and into the future. We will delve into device physics of silicon solar cells and how the limitations in present devices can be overcome for both higher efficiency and higher throughput. The various aspects of production will also be covered: from crystallization to wafering, through cell production and finishing with module design and testing.
