This current-voltage tester works by sampling various currentversus voltage combinations of the photovoltaic cell with a variable impedance load. Theperformance of the photovoltaic cell is determined by measuring this output I-V relationshipwhile it is being illuminated by light. This relationship is typically called an "I-V curve" ａnd canbe obtained by exposing the photovoltaic cell to a constant level of light while varying anexternal impedance load such that its current-voltage values change. Since multiple I-V datapoints are required to create an I-V curve, an external trigger function model is available foruse with pulse solar simulators. This allows the tester to create multiple sequential pulses（typically 10-100 points selectable） to complete the IV curve measurements. Universal input100-240VAC, 50/60Hz. Software ａnd GPIB Board is included. An external computer （soldseparately） such as the PC computer controller is required to control this current-voltagemeasurement system.Purpose of Current Vs Voltage Measurement TestA solar cell may be operated over a wide range of voltage ａnd current combinations, but thereis generally an optimum combination for maximum energy collection efficiency. By varying anexternal load resistance from zero to infinity, the optimum I-V combination where the solar celldelivers the most power can be found.Current ａnd Voltage Measurement RangeThe standard I-V Test system can measure electrical power from photovoltaic cells up to 20W.The voltage envelope is limited to 200V ａnd the current is limited to 1A. A higher powered60W version is available where the voltage is limited to 60V ａnd the current is limited to 3A.For higher loads, shunts to measure a portion of the current can be used. In general, thelimitation of the standard model is the 1A current limit. If your solar cell can generate morecurrent than 1A, then we recommend upgrading to the 60W model.Voltage Scaling FactorAlthough the maximum voltage of the base unit is 200V, the software can rescale its scanningrange to 2V, 10V, 20V or 200V. Once the scale is selected, the maximum number of I-Vmeasurement points that can be taken in that selected range is 100 points.Current Density - Voltage （J-V） MeasurementsThe software currently only measures I-V characteristics ａnd JSc （mA/cm2）, but other J-V上海市閔行區(qū)莘朱路903號（甲）廠區(qū),201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊？茖W儀器有限公司values can be derrived as J=I/area. The software outputs the I-V characteristics in an ASCIIfile which can then be read to derrive current density values.SoftwareSoftware is written in Labview, but a Labview Runtime engine allows it to run on Windows XPwithout the Labview development toolkit.System NotesThe I-V Measurement System sweeps the IV curve with an automatically adjustable resistiveload ａnd records multiple I-V data points along the way. The voltage ａnd current ranges aresoftware selectable ａnd so is the number of points taken, from 10-100 points depending onthe time length of the test allowable. The I-V data point values are then recorded ａnd plottedon a computer display ａnd saved in an ASCII text file. The points are selected by voltage,hence the voltage readings are evenly spaced.I-V Measurement BasicsFill Factor: Fill factor refers to the "squareness" of the I-V curve. It describes how closelymatched the voltage is at its maximum power point ａnd the current is also at its maximumpower point. The higher the fill factor match, the more square the I-V curve.Conversion Efficiency: The conversion efficiency of a solar cell is the percentage of lightenergy that gets converted to electrical power.References:The U.S. Department of Energy maintains a good website on how to use I-V measurementsystems in solar cell testing.

This current-voltage tester works by sampling various currentversus voltage combinations of the photovoltaic cell with a variable impedance load. Theperformance of the photovoltaic cell is determined by measuring this output I-V relationshipwhile it is being illuminated by light. This relationship is typically called an "I-V curve" ａnd canbe obtained by exposing the photovoltaic cell to a constant level of light while varying anexternal impedance load such that its current-voltage values change. Since multiple I-V datapoints are required to create an I-V curve, an external trigger function model is available foruse with pulse solar simulators. This allows the tester to create multiple sequential pulses（typically 10-100 points selectable） to complete the IV curve measurements. Universal input100-240VAC, 50/60Hz. Software ａnd GPIB Board is included. An external computer （soldseparately） such as the PC computer controller is required to control this current-voltagemeasurement system.Purpose of Current Vs Voltage Measurement TestA solar cell may be operated over a wide range of voltage ａnd current combinations, but thereis generally an optimum combination for maximum energy collection efficiency. By varying anexternal load resistance from zero to infinity, the optimum I-V combination where the solar celldelivers the most power can be found.Current ａnd Voltage Measurement RangeThe standard I-V Test system can measure electrical power from photovoltaic cells up to 20W.The voltage envelope is limited to 200V ａnd the current is limited to 1A. A higher powered60W version is available where the voltage is limited to 60V ａnd the current is limited to 3A.For higher loads, shunts to measure a portion of the current can be used. In general, thelimitation of the standard model is the 1A current limit. If your solar cell can generate morecurrent than 1A, then we recommend upgrading to the 60W model.Voltage Scaling FactorAlthough the maximum voltage of the base unit is 200V, the software can rescale its scanningrange to 2V, 10V, 20V or 200V. Once the scale is selected, the maximum number of I-Vmeasurement points that can be taken in that selected range is 100 points.Current Density - Voltage （J-V） MeasurementsThe software currently only measures I-V characteristics ａnd JSc （mA/cm2）, but other J-V上海市閔行區(qū)莘朱路903號（甲）廠區(qū),201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊？茖W儀器有限公司values can be derrived as J=I/area.

It describes how closelymatched the voltage is at its maximum power point ａnd the current is also at its maximumpower point. The higher the fill factor match, the more square the I-V curve.Conversion Efficiency: The conversion efficiency of a solar cell is the percentage of lightenergy that gets converted to electrical power.References:The U.S. Department of Energy maintains a good website on how to use I-V measurementsystems in solar cell testing.
