Hi, I'm Tomo from Agilent Technologies.
Today I'd like to demonstrate hardware emulation of solar cell by using Agilent B2960A.
Solar cell changes its output characteristics greatly by its operating condition,
such as lighting, temperature, aging, and so on.
For evaluating the load circuit of a solar cell,
you need to check it against solar cells running under various condtions.
However it's not easy to realize such condtions in a lab room.
Instead of doing so, we propose using hardware emulator for the evaluation.
Emulator can realize various characteristics of the device
and is useful for evaluating the load circuit of the device.
In this video, I measure solar cell's current-voltage characteritics
and then emulate it by the emulator.
This is a solar cell.
This is Agilent B2960A.
It can emulate the batteries.
And this is another B2960A.
It's used for measuring current-voltage characteristics.
Firstly, I will measure current-voltage characteristics of the solar cell
in good and bad lighting conditions.
I will sweep voltage from 0 to 2 V and measure the current.
Now I connect the solar cell to the meausuring instrument.
Let's move on the measurement.
Next, I measure the characterisitics in bad light condition.
This time, I use this paper to make shadow on the cell.
There are two I-V curves on the graph.
Blue and Green lines show the I-V curves in good and bad conditions respectively.
As you can see from this graph,
the voltage in bad condition is lower than that in good condtion.
Secondly, I will set up the emulator and measure its I-V characteristics.
The emulator can be set up very easily by using this tool.
I've already measured I-V characteristics of solar cell in good and bad conditions.
So I can utilize the data as parameters for the emulator.
This time I use data in good condition.
Then I send these parameters to the emulator.
And now, I connect the emulator to the meausuring instrument,
and then start measuring.
In the same way, I can do the same with data in bad condition.
this is the result.
Lines show the measurement results of actual solar cell,
and squares shows the measurement results of the emulators.
As you can see from this graph, they are exactly the same.
By using the emulator,
solar cell's current-voltage characteristics can be emulated like this.
And with this setup,
you can realize the various behavior anywhere, anytime without having the actual device.
I've demonstrated emulation of solar cell.
By using emulator like Agilent B2960A,
different characteristics of devices
including batteries, solar cells, other components or circuits, under various operating conditions
can be realized by simply changing the parameters.
This function is useful for evaluating load circuit of the device.
