NOVELTY - A self-adhesive composition comprises aliphatic polycarbonate, which is prepared by copolymerization of carbon dioxide and at least one epoxide compound selected from (2-20C)alkyleneoxide (optionally substituted with halogen, (1-20C)alkyloxy, (6-20C)aryloxy, or (6-20C)ar(1-20C)alkyl(aralkyl)oxy); (4-20C)cycloalkyleneoxide (optionally substituted with halogen, (1-20C)alkyloxy, (6-20C)aryloxy or (6-20C)ar(1-20C)alky(aralkyl)oxy); and (C8-C20)styreneoxide (optionally substituted with halogen, (1-20C)alkyloxy, (6-20C)aryloxy, (6-20C)ar(1-20C)alkyl(aralkyl)oxy, or (1-20C)alkyl).    USE - As a self-adhesive composition, useful for manufacturing self-adhesive film for glass, which is used as safety glass for building, safety glass for vehicles, safety glass for airplanes, or glass for solar light modules; and in solar cell module (claimed).    ADVANTAGE - The self-adhesive composition has excellent weather resistance, adhesive strength, transparency, and durability against ultraviolet rays; and provides high-transparent self-adhesive film that does not require an adhesive agent due to high adhesive strength to glass and does not degrade transparency even though the film becomes thicker. The self-adhesive film for glass enhances safety against to breakage of glass without the loss of transmittance even with increased thickness by improving transparency and adhesive property; is used by simple thermal attachment without an adhesive agent, thus a lamination process can be simplified; has no fear of moisture adsorption even though it is exposed to air, unlike the existing polyvinylbutyral (PVB), thus temperature, humidity, and the like need not be controlled during delivery, storage, and construction, and therefore simplifies the entire process from production to construction.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a self-adhesive film for glass manufactured from the self-adhesive composition comprising aliphatic polycarbonate by copolymerization of carbon dioxide and at least one epoxide compound; and    (2) a solar cell module comprising the self-adhesive film.
