PECT-600(FTPS): Fourier Transform Photocurrent Testing System

PECT-600 (FTPS) is the most sensitive photocurrent spectroscopy system. It is dedicated to probing tail states and charge transfer states of any kind of perovskite and organic solar cells, respectively. These spectral results facilitate analyzing loss of open circuit voltage (Voc) and enhance your scientific article quality for submitting to higher tier journals.                                      In semiconductor devices, defects are usually caused by non-ideal crystallization. Defects result in defect states or trap states in the middle of forbidden bandgap and affect the whole opto-electrical properties of devices. The signal intensities of these states are extremely weak due to their low absorption coefficients. Hence, probing and characterizing systems must be highly sensitive. Being the most sensitive photocurrent spectrometer, PECT-600 is developed to probe ultra-low intensity absorption signals by using Fourier Transform data processing technique. Using PECT-600, coupled with customized software, to characterize defect states and charge transfer states within forbidden bandgap provides quantitatively analyzed results.
