“…The solar cells were characterized by IV measurements under standard AM 1.5 illumination conditions. Figure 1 shows TEM images of 1 µm thick films that have been deposited under different hydrogen dilutions on glass [24]. It clearly demonstrates that the growth of silicon films in the protocrystalline growth regime is inhomogeneous for larger dilution ratios (R > 20), for which the transition from amorphous to microcrystalline phase can be observed.…”

“…Using Raman spectroscopy we verified that the deposition conditions described in section 2 have resulted in 300 nm thick amorphous films for the full range of dilution ratios (up to R = 40). (The films shown in Figure 1 were deposited using different conditions [24], and are shown here only to illustrate the effect of R on the phase transition. )…”

“…It is noted that the samples do not lie on the same point of the Paschen curve as illustrated by the obvious differences in p and r d , while this is known to be a way to distinguish different types of a-Si:H and their light soaking stability [32]. However, the particular samples discussed in this work can still be compared, since the deposition conditions with the lowest and highest R values are known from previous work to yield solar cells with a significantly different light soaking stability [29,65]. The samples with R values in between 0 and 10 have been added to display possible trends with more statistical certainty.…”

“…The hydrogen dilution ratio (R = [H 2 ]/[source gas]) was set to 10. At R = 10 the silicon films are still fully amorphous [5]. Additional deposition parameters were: rf power density of 34 mW/cm 2 , an inter-electrode distance of 14 mm, a substrate temperature of 235 °C and a deposition pressure of 80 Pa or 90 Pa with and without hydrogen dilution, respectively.…”
