Perovskite PV and Organic PV Voc-loss Analyzer
Boost Your PV Efficiency and Publication.
To push the conversion efficiency to the limitation of Thermodynamics, organic solar cells and perovskite solar cells strive to increase the open-circuit voltage (Voc) to Shockley-Queisser limit. REPS is a complete system that can help scientists measure, calculate, and analyze the Voc-loss in the working solar cells, and give the process improving idea for the next step.
REPS not only can detect the extremely low EL-EQE signal (as low as 10-5%, which is 7 orders of magnitude), but can also calculate thermodynamic Voc, radiative recombination Voc, and non-radiative recombination Voc (through its software SQ-VLA). In addition, it can also analyze ΔE1, ΔE2, and ΔE3 losses between different type of devices in one histogram chart. Most importantly, the analyzing software can help users match the calculated Voc-loss with the real Voc-loss of the device IV curve, thereby promoting the research progress and journal publication.
