Can green separation reagent DMPU separate different layers in PV modules?

Traditional separation reagents, such as toluene, O-dichlorobenzene, and trichloroethylene, are all highly toxic which may cause harm to human body and pollute the environment. This paper innovatively proposes using green separation reagent DMPU ( N, N′ -dimethylpropenylurea, C 6 H 12 N 2 O) to separate different layers in PV modules.

How DMPU is used to separate different layers in photovoltaic modules?

Green reagent DMPU was used to separate different layers in photovoltaic modules for the first time. The glass and backsheet in small pieces cutted from photovoltaic modules can be separated adequately in 1.5 h. Pieces of silicon wafer can keep their initial size due to the low swelling ability of DMPU.

Is DMPU a good separating reagent for PV modules?

Most of the traditional chemical swelling reagents are toxic and harmful to human health. In this study, low toxicity and environment-friendly reagent DMPU was used as the separating medium to separate different layers in PV modules.
