Measurements of State-of-the-Art Solar Cells and Modules
Dr. Cristian I. Popescu, President of Spectra-Nova Technologies, Inc.
A number of new solar cell technologies have been developed in the last years which present significant challenges to traditional testing techniques. These new devices are mostly based on thin film structures with inherent higher capacitances therefore prone to time delays in the cell response to changing light or voltage. The same is even truer for organic materials-based devices or complex structures which are asking for new test methods for improved technological control or better device understanding.
This presentation will cover the basics of solar simulation IV measurements, spectral response/quantum efficiency, electro-luminescence and other related techniques for accurate characterization of new solar cells and solar modules.
New trends in solar cell technologies will be presented briefly.

Biography: Dr. Cristian I. Popescu
Cristian has been active in photovoltaics (PV) in industry and research for over 35 years. His primary field of expertise is PV testing and measurement, PV technological equipment development, PV application development and PV technology assessment.
Cristian holds a PhD and a M.Sc. in Electrical Engineering, Polytechnic Institute of Bucharest, Romania, and is a Registered Expert on United Nations Industrial Development Organization Roster for renewable energy (solar PV).
Cristian is President and Co-fonder of Spectra-Nova Technologies, Inc., a Canadian company Ottawa-based with a world wide reputation in manufacturing PV measuring equipment. Cristian holds the position of VP-Engineering as well, the manufactured equipment being mostly based on his original designs.
The equipment manufactured by Spectra-Nova Technologies is used by a number of important solar companies and research groups all over the world: BAE Systems (USA), BP Solar and Isofoton (Spain), Shell Solar (UK and Netherlands), Dow Chemical (USA), LG Chem (Korea), Global Solar (USA), Unisolar (USA), Moser-Baer and Solar Semiconductor (India), Trina Solar and Sunwell (China), North Western University (USA), EDF and Ecole Polytechnique (France), Scancell (Norway) among others.
Spectra-Nova was nominated for Exporter of the Year award of Ottawa Chamber of Commerce in 2004.
Cristian is also President and Co-fonder of Spectra-Solaris Inc. a Canadian company dealing with special photovoltaic applications.
Most recently, he has held the position of Director of Engineering, with Newsun Technologies and Darentek Corporation manufacturing of photovoltaic production line equipment and Senior Researcher with Astris Inc., a Toronto based company developing portable fuel cells.
Prior to that he provided expertise in photovoltaic consulting services for a number of prominent companies in Canada and abroad.
In Romania, Cristian was Director and Senior Project Leader, New Energy Sources Laboratory, with The Research Institute for Electrical Engineering, in charge of laboratory activity coordination, project leader for solar cells and PV application development and main researcher for fuel cell batteries (H2/O2 and zinc-air).
His main photovoltaic projects consisted of fabrication of silicon solar cells and a PV module pilot assembly line (50kW/year throughput), PV-wind powered hydrogen pilot plant, water pumping, cathodic protection of oil pipes against corrosion, PV powered cottage, military PV power supplies and data acquisition systems.
Cristian has published 3 books, 41 scientific papers and holds 5 patents for his designs.
