Academic Research Line
infinityPV ApS offers a complete series of equipment for laboratory scale printing, testing of solar cells, analysis and imaging of solar cells. With the Academic Research Line we offer three essential pieces of equipment that allows you to do it all. The equipment counts the research laboratory coater (RLC), the UV-LED ISOSun SMU and the Academic LBIC. The Academic Research Line is cost competitive and has a small footprint and simple requirements for installation. All equipment can be operated on the desktop, in a fume cupboard or in a glovebox and the systems are upwards compatible, and it is possible to upgrade the basic system to the most advanced version at any given point.

The RLC is the creative starting point where films can be made using your materials and inks through a wide choice of deposition techniques (slot-die, flexo, knife, bar, spray etc.). The system is easily expanded to full R2R (roll-to-roll) processing by docking the printing unit onto a R2R platform. Drying of the films can be achieved using hot plate, integrated forced air, inert gas, UV or IR. The Research Laboratory Coaters are turn-key systems starting from the simple single axis slot-die coating set-up where functionality and complexity can be gradually added.
The UV-LED ISOSun SMU is an all-in-one solution for testing small laboratory solar cells under illumination. The light source is a powerful combination of UV and white light LEDs allowing illumination over an area of 16 x 16 mm2 which is typical for research laboratory substrates of 25 x 25 or 25 x 50 mm. Illumination is from below and contacting is achieved from the top using spring loaded gold contacts and we include custom sample holder for up to four junctions. The geometry is fixed by the sample holder making the unit very reproducible when comparing samples. The system also packs an SMU allowing you to measure IV-curves through the 1-to-5 multiplexer of an external sample (i.e. a sample under and external light source such as the sun or you own light source) or of one of four junctions in the sample holder illuminated by the UV-vis LED. The high available power from the LEDs allows you to synthesize your own spectrum by balancing the UV and white light components and carry out concentration experiments whereby you find saturation and current limitations.
With the academic LBIC we now have a system available at low budget that packs the same power as our industrial line with a small imaging area. The standard unit offers fast imaging of single junctions and modules over an area of 50 x 50 mm2. Its compact size means that it is easy to ship and install in almost any laboratory environment and allow you to carefully image the active areas of newly printed solar cells or LEDs (through reverse action of the LED). You establish the exact active area for accurate power conversion efficiency calculations and image defects that might stem from your printing method or impurities in your process. Often even small barriers to charge carrier transport is directly visible in the LBIC images and it is an indispensable tool in any upscaling or device development.
