Wafer-scale nanoconical frustum array crystalline silicon solar cells: promising candidates for ultrathin device applications.
نویسندگان
چکیده
A high photocurrent of 36.96 mA cm(-2) was achieved for wafer-scaled crystalline Si solar cells with hexagonal nanoconical frustum arrays at the surface. Optical simulations showed that the expected photocurrent of 10 μm thick nanostructured cells could slightly exceed the Lambertian limit.

Study the Effect of Silicon Nanowire Length on Characteristics of Silicon Nanowire Based Solar Cells by Using Impedance Spectroscopy
Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

Thin-film crystalline silicon (c-Si) solar cells with light-trapping structures can enhance light absorption within the semiconductor absorber layer and reduce material usage. Here we demonstrate that an inverted nanopyramid light-trapping scheme for c-Si thin films, fabricated at wafer scale via a low-cost wet etching process, significantly enhances absorption within the c-Si layer. A broadban...
