ORGANIC SILICON COMPOUND CONTAINING BORON, SEALANT FOR SOLAR CELL ASSEMBLY AND SOLAR CELL ASSEMBLY

摘要

Provided are an organic silicon compound containing boron, a sealant for a solar cell assembly and a solar cell assembly. The molecular skeleton of the organic silicon compound containing boron is composed of a cycloalkenyl, a silicon-oxygen bond (Si-O) and a cycloalkyl, and contains three boracic acid or borate groups bonded via a cycloalkyl. The organic silicon compound containing boron is used as a tackifier for an addition-curable organopolysiloxane composition, and can provide a sufficient and long-term stable adhesiveness for a cured product thereof in a high-temperature and high-humidity and ultraviolet light environment. In addition, an organic silicon compound containing boron with a controllable chemical structure, substantially without byproducts, and a stable quality and performance can be obtained by preparing the organic silicon compound containing boron through a hydrosilation reaction.
