SYSTEM FOR IMPROVING SOLAR CELL MANUFACTURING YIELD

摘要

A system is described for fabricating photovoltaic structures. The system can include a photovoltaic cell enclosure that communicatively couples a first processing station and a second processing station while providing a microenvironment for a plurality of photovoltaic cells. The microenvironment can be separated from a surrounding environment. Furthermore, a microenvironment controller can control density of at least one chemical that could contaminate or react with an oxide layer on a respective photovoltaic cell, thereby protecting the photovoltaic cell between processes.

1. A system, the system comprising:
a substrate enclosure that communicatively couples a first processing station and a second processing station, the substrate enclosure comprising a microenvironment for storing a plurality of processed substrates, wherein the microenvironment is separated from a surrounding environment and has an absolute humidity that is lower than 5 g/kg; and a microenvironment controller configured to control density of at least one chemical that can contaminate or react with an oxide layer on a respective substrate, thereby protecting the substrate between processes.
