These anti-reflective properties together with enhanced infrared absorption in the core-shell nanowire facilitates enhancement in external quantum efficiency using …
Advances in upconversion enhanced solar cell performance
Integration of UC layers in different solar cell types: a-Si (amorphous silicon), bifacial c-Si (crystalline silicon), DSSC (dye synthesized solar cell), and PSC (perovskite solar cell) [49, 52, 87, 88]. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
Synthesis, structural, and optical properties of (Ag/ZnS) core–shell ...
Core and shell images obtained from each nanoparticle show different contrasts, indicating that the core and shell materials differ. Infrared spectroscopy confirmed the presence of ZnS NPs around AgNPs. Incorporating Ag/ZnS into polycrystalline silicon solar cells has improved efficiency from 13.02 to 14.29%.
Convolution neural network based polycrystalline silicon photovoltaic cell linear defect diagnosis using electroluminescence images …
This paper proposes a deep learning-based automatic linear defects diagnosis solution for polycrystalline silicon photovoltaic cells based on EL images. The Hessian matrix-based defects feature extraction and a multi-scale line detector-based defect feature enhancement are adopted to achieve improved performance.

Silicon-based photovoltaic solar cells
The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900 C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …

Silicon Nanowire Solar Cells
With respect to the III-V semiconductor nanowire solar cells, there are seldom reports of silicon nanowire solar cells with axial junction, primarily due to …
Doubling Absorption in Nanowire Solar Cells with Dielectric Shell ...
Here, we show how this is possible by studying photocurrent generation for a single core-shell p-i-n junction GaAs nanowire solar cell grown on a silicon substrate. At 1 sun illumination, a short-circuit current of 180 mA cm-2 is obtained, which is more than one order of magnitude higher than that predicted from the Lambert-Beer law.
