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.
The incorporation of germanium breathes new life into solar cell technology, offering several edges over traditional silicon-based photovoltaic systems. The conversion efficiency – a key yardstick in renewable energy production – can witness marked improvement with germanium-centric solar power frameworks.
Furthermore, Ge’s wider bandgap paves the way for enhanced electron movement, thereby boosting cell efficiency. The incorporation of germanium breathes new life into solar cell technology, offering several edges over traditional silicon-based photovoltaic systems.
In 2016, Masuda [ 12] reported on the growth of multijunction germanium-based solar cells based on molecular beam epitaxy technology, and the open-circuit voltage of ~0.175 V was obtained. In 2020, Baran [ 13] studied the effect of temperature and light intensity on the conversion efficiency of Ge-based solar cells.
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.
Further exploration into improving ways of repurposing Germanium wafer may herald groundbreaking advancements that significantly uplift performance metrics like conversion efficiency and durability within high-efficiency solar cells realm.
