Effect 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 ...

Light-management Strategies for Thin-film Silicon Multijunction Solar Cells

Light management is of crucial importance to reach high efficiencies with thin-film silicon multijunction solar cells. In this contribution, we present lightmanagement strategies that we recently developed. This includes high quality absorber materials, low-refractive index intermediate reflectors, and highly transparent multiscale electrodes. Specifically, we show the fabrication of high-effic...

Design of Iii-v Multijunction Solar Cells on Silicon Substrate

With looming energy crisis across the globe, achieving high efficiency and low cost solar cells have long been the key objective for photovoltaic researchers. III-V compound semiconductor based multijunction solar cells have been the dominant choice for space power due to their superior performance compared to any other existing solar cell technologies. In spite of unmatched performance of III-...

Impurity Redistribution during Silicon Epitaxial Growth and Semiconductor Device Processing

A model has been developed that can account for both front and back "autodoping" effects during epitaxial growth as well as impurity redistribution during further high-temperature processing. The model incorporates three dopant fluxes, i.e., (i) the flux from the solid into the gas phase at the rear of the wafer, (ii) the flux from the solid to the front surface of the wafer, and (iii) the flux...
