英文摘要Spectroscopic ellipsometry (SE), high resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM) and optical transmittance measurements were used to study and establish a correlation between the open-circuit voltage (V-oc) of solar cells and the p-layer optical band gap (E-p). It is found that the ellipsometry measurement can be used as an inline non-destructive diagnostic tool for p-layer deposition in commercial operation. The analysis of ellipsometric spectra, together with the optical transmittance data, shows that the best p-layer appears to be very fine nanocrystallites with an E-p 1.95 eV. HRTEM measurements reveal that the best p-layer is composed of nanocrystallites similar to 9 nm in size. It is also found that the p-layer exhibits very good transmittance, as high as similar to 91.6% at similar to 650 nm. These results have guided us to achieve high V-oc value 1.03 V for thin film silicon based single junction solar cell. (C) 2015 Elsevier Ltd. All rights reserved.
