PROTECTIVE FILM FOR USE WITH SOLAR CELL AND THE SOLAR CELL

摘要

A protective film for use with a solar cell and the solar cell are introduced. The protective film is a protective coating formed on an anti-reflection layer of the solar cell. The protective film is characterized in that the protective coating is made of an organic material or a phosphor-containing organic material. Accordingly, the protective film dispenses with the need to make any change to a conventional solar cell-related semiconductor manufacturing process but only requires mixing the constituent ingredients of a material of which the protective coating on the anti-reflection layer is made, so as to enable ultraviolet to be partially converted into absorbable light and thus enhance the photovoltaic conversion efficiency.

1. A protective film for use with a solar cell, being a protective coating, and being formed on an anti-reflection layer of the solar cell, characterized in that the protective coating is made of one of an organic material and a phosphor-containing organic material, wherein the organic material is one selected from the group consisting of polyvinylidene fluoride (PVDF) resin, polymethyl methacrylate (PMMA) resin, silicone, and a combination of silicone and PVDF resin, wherein the phosphor in the phosphor-containing organic material is a down-converted phosphor being one of JQX(PO4)2:X3+ and JQX(PO4)2:X2+, X2+, wherein X denotes any rare earth metal, J denotes one of lithium, sodium, and potassium, and Q denotes any alkaline earth metal.
