LITOS LITE Equipment (Parallel JV and Stability Measurement for Solar Cells)
Litos Lite is a platform to perform parallel JV and stability measurements on organic and perovskite solar cells. This innovative characterization hardware can perform JV measurements on up to 56 parallel channels and stress the solar cells with either constant voltage or current. Individual MPP tracking is possible on each of the devices under stress. The temperature of the samples can be controlled to a maximum value of T = 125 °C.
Litos Lite is suitable for device stressing according to the ISOS protocols.
Litos Lite has professional, user-friendly software. This is one of the biggest assets of the instrument.
First, the user chooses their sample layout, sets device area, polarity, voltage, and current safety limits for each pixel, and can assign each pixel a tag (e.g. dead), which can then be used to select/deselect devices to measure. It is possible to save those for future use.
