    摘要： Embodiments of the invention generally relate to solar cells having reduced carrier recombination and methods of forming the same. The solar cells have eutectic local contacts and passivation layers which reduce recombination by facilitating formation of a back surface field (BSF). A patterned aluminum back contact is disposed on the passivation layer for removing current form the solar cell. The patterned back contact reduces the cost-per-watt of the solar cell by using less material than a full-surface back contact. The methods of forming the solar cells include depositing a passivation layer including aluminum oxide and silicon nitride on a back surface of a solar cell, and then forming openings through the passivation layer. A patterned aluminum back contact is disposed on the passivation layer over the holes, and thermally processed to form a silicon-aluminum eutectic within the openings.

    摘要： Embodiments of the present invention relate to a single step diffusion process used in selective emitter solar cell fabrication. In one embodiment, a dopant paste is selectively applied on a front surface of a substrate having opposite conductivity type from the dopant paste. The substrate is then exposed to a dopant containing vapor to deposit a doping layer having opposite conductivity type from the substrate on the front surface of the substrate. While the substrate is exposed to the dopant containing vapor, a portion of the dopant paste also contribute to deposition of the doping layer via gas phase transport of doping atoms from the dopant paste. The substrate is then heated in an atmosphere comprising oxygen and/or nitrogen to a temperature sufficient to cause the dopant atoms in the dopant paste and the doping layer to diffuse into the substrate, forming heavily and lightly doped emitter regions.

    摘要： Embodiments disclosed herein generally relate to a process of depositing a transparent conductive oxide layer over a substrate. The transparent oxide layer is sometimes deposited onto a substrate for later use in a solar cell device. The transparent conductive oxide layer may be deposited by a “cold” sputtering process. In other words, during the sputtering process, a plasma is ignited in the processing chamber which naturally heats the substrate. No additional heat is provided to the substrate during deposition such as from the susceptor. After the transparent conductive oxide layer is deposited, the substrate may be annealed and etched, in either order, to texture the transparent conductive oxide layer. In order to tailor the shape of the texturing, different wet etch chemistries may be utilized. The different etch chemistries may be used to shape the surface of the transparent conductive oxide and the etch rate.
