In the context of solar cells, nanotechnology enables the fabrication of structures such as quantum dots, nanowires, and thin-film solar cells. Quantum dots, for instance, are nanoscale semiconductors that can absorb and emit light with high efficiency, making them ideal for enhancing energy conversion in solar cells.
For practical nanowire solar cell design, the ideal nanowire array design for photon absorption may not necessarily optimal for nanowire solar cells. For instance, disordered nanowires can possess unequal electrical characteristics, which pose a limitation to the overall efficiency of the nanowire solar cells.
In order to fabricate nanowire solar cells in large scale, the control of the morphology of the nanowire array is essential. The early studies of MAC etching, which is mainly in (100) and (111) substrates, have concluded that the etching is isotropic and nanowires are always vertically formed on the substrate surface, , .
Nanotechnology is playing a crucial role in advancing each generation of solar cells: Crystalline silicon solar cells represent the first generation of solar technology and currently dominate the global market. These cells are known for their high efficiency, with modern versions achieving efficiencies of up to 26.7%.
Novel multilayer nanorainforest solar cells based on p-Si nanopillar array/n-CdS nanoparticles/n-ZnO nanowire array heterostructures were fabricated via a highly accessible, reproducible and controllable fabrication process, meaning that this wafer-scale, low-cost and easily controlled processing has potential on nanostructure PV devices.
Being similar with SiNWs grown by the VLS growth mechanism, the regularity of nanowire arrays is critical to acquire high efficiency solar cells. The fabrication of ordered nanowire arrays can also be achieved by using templates.
