Abstract
A apparatus and method for manufacturing a photovoltaic module includes components for heating the module and applying an electrical bias to the module to improve photovoltaic module performance and manufacture multiple photovoltaic modules with similar performance.
Claims12
A method for manufacturing a photovoltaic module, comprising:
- heating a photovoltaic module;
- applying an electrical bias to electrodes of the photovoltaic module while the photovoltaic is at an elevated temperature from said heating, wherein the heating and applying an electrical bias are performed in dedicated association with each other;
- and
- exposing the photovoltaic module to light while applying the electrical bias.

A method of manufacturing a photovoltaic module, comprising:
- performing a first test of at least one performance characteristic of a photovoltaic module;
- if the at least one performance characteristic of the photovoltaic module is identified to be below a minimum level, processing the photovoltaic module by heating and electrical biasing;
- and
- performing a second test of the at least one performance characteristic of the photovoltaic module.
