Passivating Polysilicon Recombination Junctions for Crystalline Silicon Solar Cells

Amorphous silicon carbide passivating layers for crystalline-silicon-based heterojunction solar cells

Passivating electron contact based on highly crystalline nanostructured silicon oxide layers for silicon solar cells

We present a novel passivating contact structure based on a nanostructured silicon-based layer. Traditional poly-Si junctions feature excellent junction characteristics but their optical absorption induces current losses when applied to the solar cell front side. Targeting enhanced transparency, the poly-Si layer is replaced with a mixed-phase silicon oxide/silicon layer. This mixed-phase layer...

Recombination in compensated crystalline silicon for solar cells

Deliberate compensation of crystalline silicon results in a decrease in the equilibrium carrier concentration, which leads to an increased carrier lifetime for the intrinsic recombination processes of Auger and radiative recombination. We present modeling which reveals that compensation also often leads to a significant increase in lifetime for recombination through defects via the Shockley–Rea...

Crystalline Silicon Solar Cells

Front page headlines in the New York Times and the Wall Street Journal in 1954 heralded to the world the demonstration of the first reasonably efficient solar cells, an event made possible by the rapid development of crystalline silicon technology for miniaturised electronics. Since that time, the majority of solar cells fabricated to date have been based on silicon in monocrystalline or large-...

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 ...
