    摘要: The present invention relates to UV curable encapsulant compositions based on acrylic and/or methacrylic block copolymers, to structures containing these compositions especially photovoltaic cells and to the use of these compositions in photovoltaic cells. The liquid encapsulant composition according to the invention comprises: an acrylic or methacrylic block copolymer, at least one acrylic or methacrylic monomer and/or oligomer, and at least one photo initiator. wherein said acrylic or methacrylic block copolymer is of the general formula B- (A)n, wherein: n is a natural integer greater than or equal to 1, B represents an acrylic or methacrylic polymer block composed of a sequence of monomer units which may be polymerized by the radical route, the overall Tg of which is less than 0°C, A is an acrylic or methacrylic polymer block composed of a sequence of monomer units which may be polymerized by the radical route, the overall Tg of which is greater than 0°C, block B represents at least 50%, and preferably from 60% to 95% w/w of the block copolymer.
