It has been demonstrated that n-layer of 16-nm, intrinsic layer (i-layer) of 0.5-μm and p-layer of 3-μm thickness with specific doping concentrations of 1·1020 cm–3 for n-layer and 1·1018 cm–3 for p-layer allow us to achieve the maximum efficiency 29.21%. The solar cell structure provides an open circuit voltage of 1.0 V, short circuit current density of 33.15 mA/cm2 and the percentage of fill factor value of 88.03%. However, the efficiency drops drastically, if the dislocation density in i-layer is higher than 1·1014 cm–3, and unintentional doping concentration within i-layer is beyond 1.5·1016 cm–3 of the structure.
