Smart PV and OLED Multiplexor Test Board with JV Sweep Software

Order Code: E541-S101
Not in stock

This measurement system is designed to enable OLED and PV testing and characterisation via intuitive Easy JV Sweep software. Comprised of a main multiplexor board, an interchangeable substrate board and control software, the system allows academics and researchers to conduct a number of measurements including:

  • JV sweeps and PV figures of merit (PCE, FF, Jsc, etc)
  • JVL sweeps and efficacy (as photocurrent/driving current) for OLED
  • Lifetime testing and environmental degradation studies

Please note that the Easy JV Sweep software requires the Keithley 2612B SMU (see Note 1).

Smart PV and OLED Board
Smart PV and OLED Multiplexor Board.


We have designed the Smart PV and OLED Board, along with Easy JV Sweep software, to be as versatile as possible and incredibly easy to use in order to save time and speed up the research process. 

The Smart PV and OLED Board is intended to be used with a Source Meter. Easy JV Sweep software has been designed for use with the Keithley 2612B SMU (see note 1). Should you wish to use an alternative SMU and write your own program, you can incorporate the Smartboard control code in the section "Sample Code to Control the Smartboard" at the bottom of the page.

This product is covered by our FREE 2-year warranty



An interchangeable substrate board means the multiplexer is compatible with all Ossila substrate systems.


Easy to Use

Easy JV Sweep control software is included with the system; there is no need to learn a programming language to use the multiplexer or calculate the device figures of merit. The software has an intuitive user interface and takes less than an hour to set up and run a basic sweep.

The hardware and software also enable easy performance of lifetime or degradation studies. The test board can be easily mounted on an optical breadboard too, due to it being drilled with M6 (1/4 inch) bolt holes.


Time Saving

The multiplexer automatically acquires up to eight pixels per substrate, which means there is no need to use manual switches. Data is conveniently saved in spreadsheet files - one file per substrate - which makes data analysis fast and simple.



Spring-loaded probes (pogos) combined with a push-fit bracket allow for easy loading and unloading of substrates, whilst providing good, repeatable electromechanical connection to the substrate pixels.

Moreover, the smart circuit board design, combined with high quality components, helps to minimise the effects of environmental noise. Extremely low resistance and capacitance of the multiplexer measurement channel guarantee that the Smart PV and OLED board will not affect the outcome of the measurement.

With more than 5 years experience in design and manufacturing PV and OLED fabrication and measurement equipment, Ossila prides itself on producing high quality products and has extensively tested the Smart PV and OLED Board in order to ensure it delivers on excellent performance.



For those who would like to write their own control software, we have designed the board so that it is compatible with the following languages:

  • LabVIEW
  • MATLAB - see example code
  • LabWindows/CVI
  • Measurement Studio
  • Visual Basic
  • Visual Studio
  • Visual Studio .NET

Extra Features

  • Programmable fan (to control temperature)
  • Reference photodiode (useful for tracking the behaviour of the solar simulator lamp and promptly assess whether the lamp is ageing)
  • Automatic control of the solar simulator (for PV measurements)
  • Compatible with Linux, MacOS, PocketPC and Windows


Easy JV Sweep Control Software

Sample Code to control the SmartBoard

We've put together some sample code for use with the SmartBoard which can be downloaded below. The code simply controls the SmartBoard so you can use any type of SMU to carry out measurements or you can incorporate it into your own program. If you do not have labView installed on your computer, you can download the LabView executable code (you may need to download the LabVIEW Run-Time Engine from to run this)
