Distinguished Lecture 1 – “Perovskite solar cells: The new frontier for photovoltaic device” by Professor Vikram Dalal
Perovskite solar cells are potentially a new and important technology for increasing the efficiency of solar cells. They are based on a hybrid inorganic-organic material, organo-metallic halides, which re very good absorbers of light. The material also possesses excellent electronic properties, and as a consequence, very good solar cells can be made from this material. In this talk I will describe the various methods for making p0erovskite cells and their basic physics, as well as potential problems such as stability.
Vikram Dalal is Distinguished Professor of Electrical and Computer Engineering at Iowa State University in the U.S. He is a Fellow of IEEE, American Physical Society and AAAS, and has 40+ years of experience in PV R&D.
Distinguished Lecture 2 – “Photovoltaics History, Technology, Innovation, and Progress: The Future is Now . . .” by Professor Lawrence L. Kazmerski
“New York Times, April 26, 1954: MURRAY HILL, N.J.—A solar battery, the first of its kind, which converts useful amounts of the sun’s radiation directly and efficiently into electricity, has been constructed here by Bell Telephone Laboratories . . . It may mark the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams—the harnessing of the almost limitless energy of the sun for uses of civilization.”
This announcement market a subtle change in the direction of our electricity future. The birth of modern photovoltaics (PV) traces only to the mid-1950s, with the Bell Telephone Laboratories’ development of an efficient, single-crystal Si solar cell. The inventors (Daryl Chapin, Calvin Fuller, and Gerald Pearson) did not envision that their 2-cm2, 6%-efficient solar cell would lead to our world of electricity projecting terawatts generated from this simple device. They did not really foresee the surge of manufacturing and deployment in Asia, the embracing of the green-energy benefits in Europe, and the paradoxical investment in these technologies by the petroleum-abundant Arab countries—nor the evolvement from those milliwatts of the 1950s to the multi-GW production of today. Since then, Si has dominated the technology and the markets, from space through terrestrial applications. In this presentation, we examine the current status of PV—where we are with the technology (costs, manufacturing, markets) and the industry. We will examine at the status of R&D, markets, manufacturing, and technical investments. And look toward what is coming—the prospects, potential, gaps, needs, and coming generations of solar electricity. We illustrate the role and importance of innovation and vision in technology development. We will have a critical examination of the technologies (from crystalline Si through thin films—and beyond!). We will look back to time, providing insights into the early innovators and visionaries—their motivations, their expertise, and how these beginnings have brought us closer “the realization of one of mankind’s most cherished dreams.” And we stress that the “future of photovoltaics” is already here!
Lawrence L. Kazmerski is Emeritus Research Staff Member of the National Renewable Energy Laboratory, Golden, Colorado, having last served as Executive Director Science and Technology Partnerships at NREL 2009-2013. He is currently Research Professor at the University of Colorado Boulder, with the Renewable and Sustainable Energy Institute (RASEI). Previously, Kazmerski served as the founding Director of the National Center for Photovoltaics (NCPV) for the period 1999 through 2008. He received his B.S.E.E. (1967), M.S.E.E. (1968) and Ph.D. (1970) in electrical engineering—all from the University of Notre Dame. He served a postdoctoral position with the Atomic Energy Commission at the Notre Dame Radiation Research Laboratory, January through August 1971. He was on the electrical engineering faculty (Associate Professor) at the University of Maine before coming to the Solar Energy Research Institute (SERI-which became NREL in 1991) in 1977. His research at Maine included NSF- and ERDA-funded work in thin-film photovoltaics and the report of the first thin-film copper-indium-diselenide (CIS) solar cell. He was SERI’s (NREL’s) first staff member in photovoltaics, hired specifically to establish research efforts in characterization off photovoltaic materials and de vices; he led NREL efforts in measurements and characterization for more than 20 years. Kazmerski has more than 325 publications and some 200 invited talks. He holds 4 patents for instrument development, which resulted in 4 R&D 100 Awards. His research interests included the DOE Office of Science Energy Frontiers Research Center (EFRC) at NREL dealing with “materials-by-design” (www.centerforinversedesign.
Distinguished Lecture 3 – “PV Module Performance Loss due to Degradation and Soiling” by Professor Anil Kottantharayil
Deployment of photovoltaic systems in India has ramped up tremendously since the commencement of the National Solar Mission in 2010. The deployment target for 2022 is 100 GW and for 2030 it is 300 GW. The rapid adoption of electric vehicles in the future would significantly enhance the scope of photovoltaic system deployment in the country. These ambitious deployment targets require upwards of Rs 2 lakh crores of investment. The primary return on this investment is the electricity harvested from these systems. In this talk we would discuss the degradation of solar PV panels and soiling of the panels and their impact on energy yield of PV systems.
NCPRE at IIT Bombay had been conducting All India Surveys of Photovoltaic Module reliability since 2013. In this presentation we would present an overview of the major results of these surveys. Various mechanisms of degradation observed in different climatic zones of the country would be presented.
We have been also conducting studies on the impact of soiling on the energy yield of photovoltaic systems. Typical energy yield loss rates observed in Mumbai, and the potential solutions for mitigating soiling losses would be presented. Various challenges in the implementation of these solutions would be also discussed.
This talk would address some of the key technological challenges in the deployment of large scale PV in one of the largest markets in the world. This is expected to inform the researchers and other technical personal from the academia and industry on the opportunities.
Anil Kottantharayil received the B. Tech. degree in electronics and communication engineering from the National Institute of Technology Calicut, in 1993, the M. Tech. degree in electrical engineering from the Indian Institute of Technology Bombay, Mumbai, India, in 1997, and the Dr.Ing. degree (summa cum laude) from the Universitat der Bundeswehr, Munich, Germany, in 2002.
