Solar Cell Efficiency Measurements
Summary The calibration and efficiency measurement procedures followed by the PV Devices and Measurements Branch at the Solar Energy Research Institute (SERI) are presented. The use of spectral irradiance measurements to cali- brate reference cells used in these measurements has reduced the uncertainty in the calibration number to less than 1%. The use of the spectral mismatch index can reduce ...

A 21.5% efficiency silicon solar cell
SunPower Corp., a subsidiary of Cypress Semiconductor Corp., announced that its A-300 silicon solar cell had been measured at 21.5 percent efficiency by the National Renewable Energy Laboratory (NREL) in Golden, Colorado. SunPower’s A-300 solar cell was manufactured in the company’s Round Rock, Texas pilot line. SunPower’s A-300 solar cells offer a significant efficiency improvement over ...

Contacting bare solar cells for STC Measurements
Abstract : Accuracy in the measurement of solar cell performance attains more and more economic significance additionally to its importance in technology development. Measurement of bare (without additional interconnectors on the bus bars) wafer based silicon solar cells directly in production with a high relative accuracy is important for cell sorting and a high absolute accuracy is necessary ...

Optimum performance solar cells using atmospheric pressure chemical vapour deposition deposited TCOs
High performance transparent conducting oxides (TCOs), have significance for optimising PV performance. We have developed an advanced atmospheric pressure chemical vapour deposition process, by applying fast experimentation and using a combinatorial chemistry approach to aid the studies. The deposited films were characterised for crystallinity, morphology (roughness), haze and resistivity to aid ...

2nd Progress meeting on the APOLLON project
2nd Progress meeting on the APOLLON project Introduction In Piacenza, Italy, has been held the 2nd progress meeting of the APOLON Project, so far the biggest integrated Photovoltaic project of FP7 whose main final objective is the development of point focus (PF) and dense array (DA) systems with a target cost of 2 Euro/W. In order to answer to the industrial need to speed up the ...

Water vapour permeation measurement for PV Solar Cell packaging
With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries. As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies. At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter technology ...

Advanced system for calibration and characterization of solar cells
This paper presents high performance setup developed at the SolarLab to measure curient-voltage (I—V) curves of solar cells. The core of a setup is a steady light solar simulator of class A, according to specifications oflEC 60904-9 andASTM E927 standards. Available range of measurements enables us to characterise not only all kinds of silicon wafer-based solar cells but also thin film ...
