Abstract

An improved solar cell designed for optimum efficiency is comprised of a plurality of series connected unit solar cells formed from a common substrate of semiconductor material. Each unit solar cell has spaced elongate sidewalls, and a ''dead space'' area between adjoining sidewalls of adjacent units is made substantially smaller than an active, light receiving area, extending between the opposite sidewalls of each individual unit. In addition, the width of the active area is concisely limited to ensure that radiation incident on the active area is incident at a point which is spaced from the p-n junction of each unit by no more than a predetermined optimum distance. Reducing the ''dead space'' area while concisely limiting the width of the active area provides improved solar cell performance without requiring focusing lenses.

Solar cell. [array of cell on common substrate]

Patent Kaplow, R; Frank, R

An improved solar cell designed for optimum efficiency is comprised of a plurality of series connected unit solar cells formed from a common substrate of semiconductor material. Each unit solar cell has spaced elongate sidewalls, and a dead space area between adjoining sidewalls of adjacent units is made substantially smaller than an active, light receiving area, extending between the opposite sidewalls of each individual unit.

Method of making a solar-cell array

Patent Kaplow, R; Frank, R; Goodrich, J

The invention contemplates a method of making a solar-cell construction wherein plural spaced elongate unit cells of an array are formed from a parallel-grooved single wafer of substrate material of a first conductivity type, with adjacent sidewalls of adjacent units at each inter-unit groove formation. In the transverse succession of such groove formations, the sidewalls of every other groove are formed with regions of a second conductivity type, so that at or near the radiation-exposure surface of each unit there is but one junction between first and second conductivity types. In one general form, all grooves go all the waymore »« less
Solar cell device having two heterojunctions

Patent Ettenberg, M; Kressel, H

A body of semiconductor material of a solar cell device has a surface a portion of which is exposed to incident solar radiation, and a surface opposite the incident surface. At the incident surface and in the body is a first region having a bandgap energy greater than 2.1 eV and thus is substantially transparent to solar radiation. Spaced from the first region and at the opposite surface is a second region which is of a material having a bandgap energy in the range of 1.5 eV to 1.9 eV. Between and in contact with both first and second regionsmore »« less
Method of making a high intensity solar cell

Patent Sater, B

A method of manufacturing a high intensity edge illuminated solar cell is provided which comprises the following steps. A semiconductor substrate is formed having first, second and third essentially parallel layers having impurity doped semiconductor material and arranged in that order with the first and third layers terminating in opposing essentially parallel first and second major surfaces. The second layer is of a first type conductivity and the first layer is an opposite second type conductivity so as to define a PN junction between the first and second layers and which junction is essentially parallel to the first and secondmore »« less
Photovoltaic solar cell

Patent Nielson, Gregory; Okandan, Murat; Cruz-Campa, Jose; ...

A photovoltaic solar cell for generating electricity from sunlight is disclosed. The photovoltaic solar cell comprises a plurality of spaced-apart point contact junctions formed in a semiconductor body to receive the sunlight and generate the electicity therefrom, the plurality of spaced-apart point contact junctions having a first plurality of regions having a first doping type and a second plurality of regions having a second doping type.
