A high efficiency configuration for a solar cell module comprises solar cells conductively bonded to each other in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency.

Shingled solar cell module

Shingled solar cell module comprising hidden tap interconnects

A high efficiency configuration for a solar cell module comprises solar cells conductively bonded to each other in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. The front surface metallization patterns on the solar cells may be configured to enable single step stencil printing, which is facilitated by the overlapping configuration of the solar cells in the super cells. A solar photovoltaic system may comprise two or more such high voltage solar cell modules electrically connected in parallel with each other and to an inverter. Solar cell cleaving tools and solar cell cleaving methods apply a vacuum between bottom surfaces of a solar cell wafer and a curved supporting surface to flex the solar cell wafer against the curved supporting surface and thereby cleave the solar cell wafer along one or more previously prepared scribe lines to provide a plurality of solar cells. An advantage of these cleaving tools and cleaving methods is that they need not require physical contact with the upper surfaces of the solar cell wafer. Solar cells are manufactured with reduced carrier recombination losses at edges of the solar cell, e.g., without cleaved edges that promote carrier recombination. The solar cells may have narrow rectangular geometries and may be advantageously employed in shingled (overlapping) arrangements to form super cells.

System for manufacturing a shingled solar cell module

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. Each super cell comprises a plurality of rectangular or substantially rectangular silicon solar cells arranged in line with long sides of adjacent silicon solar cells overlapping and conductively bonded directly to each other to electrically connect the silicon solar cells in series. A super cell may comprise a hidden tap contact pad located on a back surface of a solar cell located at an intermediate position along the super cell. In some variations the overlapping sides of adjacent silicon soar cells in a super cell are flexibly bonded to each other, and a flexible electrical interconnect is rigidly bonded to one of the solar cells.

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency.

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. In some variations a solar module comprises a white backing sheet on which rows of super cells are arranged, and the white backing sheet comprises darkened stripes having locations and widths corresponding to gaps between the rows of super cells such that white portions of the backing sheet are not visible through the gaps between the rows of super cells.

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. The solar cell module may comprise for example a series connected string of N greater than or equal to 25 rectangular or substantially rectangular solar cells having on average a breakdown voltage greater than about 10 volts, with the solar cells grouped into one or more super cells each of which comprises two or more of the solar cells arranged in line with long sides of adjacent solar cells overlapping and conductively bonded to each other, and with no single solar cell or group of &#x3c;N solar cells in the string of solar cells individually electrically connected in parallel with a bypass diode.

A method of forming a planar waveguide structure, comprising forming a first graded layer on a substrate, wherein the first graded layer comprises a first and a second optical material, wherein the concentration of the first optical material increases with the height of the first graded layer; forming a second graded layer on the first graded layer, the second graded layer comprising the first and second optical materials wherein the concentration of the first optical material decreases with the height of the second graded layer. The method further including forming a uniform layer on the first graded layer, the uniform layer containing first and second optical materials wherein the first optical material concentration is constant.
