A MONOLITHICALLY INTEGRATED SOLAR CELL SYSTEM

摘要

A monolithically integrated system of silicon solar cells. A system having a silicon substrate and a plurality of solar cells formed on the silicon substrate. Each solar cell can have an emitter portion and a base portion. The system can also have a plurality of intermediate regions, each intermediate region having a polarity and electrically separating at least two portions of adjacent solar cells from one another such that the polarity of the intermediate region is opposite to a polarity of at least one of the separated portions of the adjacent solar cells.

1. A monolithically integrated system of silicon solar cells, the system comprising:
a silicon substrate; a plurality of adjacent solar cells formed using the silicon substrate, each solar cell comprising a base portion and an emitter portion, whereby the plurality of solar cells comprises a plurality of adjacent base portions and a plurality of adjacent emitter portions; and a plurality of intermediate regions, each intermediate region comprising: a first doped silicon portion arranged to electrically separate at least one of the base portions from at least one adjacent base portion, the first portion having a polarity that is opposite to that of the base portions; and a second doped silicon portion arranged to electrically separate at least one of the emitter portions from at least one adjacent emitter portion, the second portion having a polarity that is opposite to that of the emitter portions;wherein the intermediate regionselectrically isolate adjacent solar cells from each other.
