In this paper, germanium-based solar cells were designed based on germanium (Ge) materials, and the cross-cone (CC) nanostructures were used as the absorber layer of the solar cells. The optical path inside the absorber layer was increased by microstructure reflection, thereby increasing the absorption efficiency of the germanium-based solar cell.
By exploring the electrical performance of the device under different Ge nanostructure parameters, a germanium-based solar cell device under the nanocross-cone absorption structure array with both high-efficiency light absorption and excellent electrical performance was finally obtained.
The VOC of the germanium-based solar cells under the single-junction CC nanostructure absorber structure array is 0.31 V, and the JSC reaches 45.5 mA/cm 2. The FF value of the device can be calculated as 72.7% by Equation (4). The η of the device of 10.3% can be reached by Equation (5).
It is mainly used in the field of optical fiber communication. Germanium has good light transmittance within the infrared wave band and opacity in the visible spectrum. It is the most common material for making infrared optical lenses, lens blanks, and infrared optical windows within the wave band range of 2-14μm.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
