Abstract:

A backsheet () for use in a photovoltaic cell module () comprises a fluororesin () and a plurality of encapsulated particles () dispersed in the fluororesin (). Each of the encapsulated particles () dispersed in the fluororesin () comprises a core particle (), which comprises titanium dioxide (TiO). Each of the encapsulated particles () further comprises a metal oxide layer () disposed about the core particle (). Further, each of encapsulated particles () also comprises an organic protective layer () disposed about the metal oxide layer (). A photovoltaic cell module () comprising the backsheet () is also disclosed.
