Three-dimensional (3D) silicon (Si) nanostructures have attracted much attention in solar
cells due to their excellent broadband and omnidirectional light-harvesting properties …

We demonstrated that hierarchical structures combining different scales (ie, pyramids from
1.5 to 7.5 μm in width on grooves from 40 to 50 μm in diameter) exhibit excellent broadband …

Ultrathin crystalline silicon (c‐Si) solar cells provide advantages in reducing the use of c‐Si
material and being flexible, but there are several challenges that need to be conquered …

Silicon‐based cells could convert more solar energy to electrical energy if the cells could
absorb more light. However, the nanostructured cells have demonstrated relatively low …

In this paper, a record-breaking efficiency of 12.3% is experimentally demonstrated for a
flexible free-standing, 2.7-μm-thick ultrathin crystalline silicon (c-Si) solar cell, which is the …

Optimally designed Si nanostructures can serve as effective light trapping structures for
flexible crystalline ultrathin Si solar cells. In this study, we develop a unique quasi …

Introducing nanophotonics into photovoltaics sets the path for scaling down the surface
texture of crystalline-silicon solar cells from the micro-to the nanoscale, allowing to further …

Hierarchical silicon structures consisting of micropyramids and nanowire arrays are
fabricated by two-step chemical etching processes aimed at achieving cost and time …

In this paper, we have explored manufacturable approaches to sub-wavelength controlled
three-dimensional (3D) nano-patterns with the goal of significantly enhancing the …

Although black silicon is used widely as an antireflection coating in solar cells, the
corresponding electrical properties are usually poor because the accompanied enlarged …
