“…The increase in process pressure decreases the kinetic energy of the dopant atoms. This reduces surface diffusion and decreases the amount of active dopants and subsequently the carrier concentration[21]. Besides, the reduction of the carrier concentration with the pressure could be explained in terms of segregation of Al content into the grain boundaries.…”

“…For long wavelengths (650-800 nm), the AlTi films have a reflectance of around 85%-88%, while the Ag film has a reflectance of around 97%. The lower reflectance of the AlTi films at higher pressure can be explained by more collision among sputtered atoms and argon ions, lowering the density of the sputtered films [18]. This is also reflected by the measurement of the refractive index, as shown in Figure 1b.…”

Abstract:In this study, metal films are fabricated by using an in-line reactive direct current magnetron sputtering system. The aluminum-titanium (AlTi) back contacts are prepared by changing the pressure from 10 mTorr to 25 mTorr. The optical, electrical and structural properties of the metal back contacts are investigated. The solar cells with the AlTi had lower contact resistance than those with the silver (Ag) back contact, resulting in a higher fill factor. The AlTi contact can achieve a solar cell conversion efficiency as high as that obtained from the Ag contact. These findings encourage the potential adoption of AlTi films as an alternative back contact to silver for silicon thin-film solar cells.

“…Currently, two HJ structures, namely, n-type indium tin oxide (n-ITO)/n-Si and n-type ZnO-base/n-Si, are commonly investigated; the optimal conversion efficiency of which is 16.5 %, as achieved by Kobayashi et al [10], and 9.4 %, as demonstrated in our previous study (Al-Y co-doped ZnO/n-Si) [11], respectively. However, the low build-in potential (V bi ) of the N-N structure limits the open circuit voltage (V oc ) of the cell.…”

This study investigates the effects of sputtering power on the performance of p-Ni 1-x O:Li/n-Si heterojunction solar cells (HJSCs). The results of this study indicate a strong dependence of the cell characteristics on the sputtering power. Extremely high or low sputtering power generates higher interface state density (D it ), resulting in the lowering of open circuit voltage (V oc ) and fill factor (FF). The cell fabricated at a sputtering power of 100 W has the lowest D it of 7.08 9 10 11 cm -2 eV -1 , corresponding to the highest conversion efficiency (g) of 4.30 % [short circuit current density (J sc ): 18.06 mA cm -2 , V oc : 390 mV, FF: 61.1 %, series resistance (R s ): 4.3 Xcm 2 and shunt resistance (R sh ): 478.75 Xcm 2 ]. Furthermore, the cell exhibits a considerably poor temperature coefficient of -0.70 %/°C (J sc : ?0.07 %/°C, V oc : -0.52 %/°C and FF: -0.29 %/°C) when compared with conventional solar cells. Further improvement in the D it of the cell is highly imperative for developing p-Ni 1-x O:Li/n-Si HJSCs with a high conversion efficiency and a good temperature coefficient.
