INCREASED POWER OUTPUT OF CRYSTALLINE SILICON SOLAR MODULES BY APPLICATION OF NEW MODULE CONCEPTS

摘要

The aim of this work was to analyze new module concepts and their influence on the electrical power output. Alternative methods for the soldering of interconnections between solar cell busbars and solar cell tabs, the replacement of standard flat ribbons by means of innovative grooved connection wires and the use of new developed encapsulations were investigated and characterized. One emerging possibility to overcome the shortcomings of soldering is the use of electrically conductive adhesives. By replacing a standard flat ribbon by a grooved solar cell interconnect wire (Light Capturing Ribbon - LCR) an increase of the efficiency of a solar module is expected by reflecting more light back onto the surface of the solar cell. New thermoplastic materials allow a faster and cheaper production process, a reduced moisture permeability and a higher UV-transmission.
