High - Effi ciency Amorphous Silicon Solar Cell on a Periodic Nanocone Back Refl ector
Thin-fi lm silicon solar cells, including hydrogenated amorphous silicon (a-Si:H) single-junction and amorphous/microcrystalline silicon (a-Si:H/ μ c-Si:H) tandem-junction solar cells, are promising candidates for the global terawatt-scale deployment of photovoltaics thanks to the abundance and non-toxicity of their raw materials, and mature fabrication processes. [ 1 , 2 ] Compared to their tr...
متن کاملHybrid silicon nanocone-polymer solar cells.
Recently, hybrid Si/organic solar cells have been studied for low-cost Si photovoltaic devices because the Schottky junction between the Si and organic material can be formed by solution processes at a low temperature. In this study, we demonstrate a hybrid solar cell composed of Si nanocones and conductive polymer. The optimal nanocone structure with an aspect ratio (height/diameter of a nanoc...
متن کاملOptical absorption enhancement in amorphous silicon nanowire and nanocone arrays.
Hydrogenated amorphous Si (a-Si:H) is an important solar cell material. Here we demonstrate the fabrication of a-Si:H nanowires (NWs) and nanocones (NCs), using an easily scalable and IC-compatible process. We also investigate the optical properties of these nanostructures. These a-Si:H nanostructures display greatly enhanced absorption over a large range of wavelengths and angles of incidence,...
متن کاملAmorphous Silicon–based Solar Cells
Crystalline semiconductors are very well known, including silicon (the basis of the integrated circuits used in modern electronics), Ge (the material of the first transistor), GaAs and the other III-V compounds (the basis for many light emitters), and CdS (often used as a light sensor). In crystals, the atoms are arranged in near-perfect, regular arrays or lattices. Of course, the lattice must ...
متن کاملEffect of Silicon Nanowire on Crystalline Silicon Solar Cell Characteristics
Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...
