摘要： Contact holes of solar cells (420) are formed by laser ablation to accommodate various solar cell designs. Use of a laser to form the contact holes is facilitated by replacing films formed on the diffusion regions with a film (424) that has substantially uniform thickness. Contact holes may be formed to deep diffusion regions to increase the laser ablation process margins. The laser configuration may be tailored to form contact holes through dielectric films of varying thicknesses.

摘要： A contact mask for inkjet printing on a solar cell substrate (223) may be generated by creating a printing bitmap (213) of contacts to be printed on the solar cell substrate (223). The contacts may be located (214) on the solar cell substrate (223) by mapping coordinates of the printing bitmap (213) to coordinates of the solar cell substrate (223) as positioned in the inkjet printer (220). The location of the contacts on the solar cell substrate (223) may be defined relative to a location on the solar cell substrate (203), such as relative to center of mass. The contact mask may be printed by the inkjet printer (220) using the printing bitmap (213) and location information (214) of the contacts.

摘要： A superstrate, such as a sheet of polymer film (310), is used as a transport during metallization of solar cells (130). The back sides of the solar cells (130) are attached to the sheet of polymer film (310). Contact holes are formed through the sheet of polymer film (310) to expose doped regions of the solar cells (310). Metals are formed in the contact holes to electrically connect to the exposed doped regions of the solar cells (130). The metals are electroplated to form metal contacts (354, 355) of the solar cell (130). Subsequently, the solar cells (130) are separated from other solar cells that were metallized while supported by the same sheet of polymer film (310) to form strings of solar cells or individual solar cells.

摘要： A solar cell fabrication process includes printing of dopant sources (105,106) over a polysilicon layer (104) over backside of a solar cell substrate. The dopant sources (105,106) are cured to diffuse dopants from the dopant sources (105,106) into the polysilicon layer (104) to form diffusion regions (107,108), and to crosslink the dopant sources (105,106) to make them resistant to a subsequently performed texturing process. To prevent counter doping, dopants from one of the dopant sources (105,106) are prevented from outgassing and diffusing into the other dopant source. For example, phosphorus from an N-type dopant source (106) is prevented from diffusing to a P-type dopant source (105) comprising boron.

摘要： A bipolar solar cell (100) includes a backside junction formed by an N-type silicon substrate (101) and a P-type polysilicon emitter (108) formed on the backside of the solar cell (100). An antireflection layer (103) may be formed on a textured front surface of the silicon substrate (100). A negative polarity metal contact (102) on the front side of the solar cell (100) makes an electrical connection to the substrate (101), while a positive polarity metal contact (110) on the backside of the solar cell (100) makes an electrical connection to the polysilicon emitter (108). An external electrical circuit may be connected to the negative and positive metal contacts to be powered by the solar cell (100). The positive polarity metal contact (110) may form an infrared reflecting layer with an underlying dielectric layer (109) for increased solar radiation collection.

摘要： A method of fabricating a solar cell can include forming a first dopant region over a silicon substrate and an oxide region over the first dopant region. In an embodiment, the oxide region can protect the first dopant region from a first etching process. In an embodiment, a second dopant region can be formed over the silicon substrate, where a mask can be formed to protect a first portion of the second dopant region from the first etching process. In an embodiment, the first etching process can be performed to expose portions of the silicon substrate and/or a silicon region. A second etching process can be performed to form a trench region to separate a first and second doped region of the solar cell. A third etching process can be performed to remove contaminants from the solar cell and remove any remaining portions of the oxide region.
