Bi 2 MoO 6 samples with different morphologies have been prepared using co-precipitation and hydrothermal methods. Octahedral-, spherical-, and plate-like particles have been obtained by changing some external factors including preparation methods, solvent types, and surfactants. Our results suggest that pure Bi 2 MoO 6 phase with nanoplate morphology are easily obtained via hydrothermal preparation method using ethylene glycol solvent. The photocatalytic and photoelectric properties of these Bi 2 MoO 6 samples have also been investigated in detail. Moreover, the photocatalytic activity is enhanced with addition of surfactants, such as Polyvinylpyrrolidone (PVP), Sodium dodecylsulfate (SDS), andcetytrimethylammonium bromide (CTAB). The excellent photocatalytic activity is found for CTAB addition, which is nearly 100. It may be ascribed to the specifically exposed facets structure, which is related to larger visible light absorption and improved separation of photogenerated charge carriers.

Taking advantage of three-dimensional software Solidworks to model for solar modules and also using finite element analysis software Ansysworkbench to conduct the stress analysis and strength check of modules, to analyze the deformation of modules under certain loading conditions, to conduct load tests and defect detection (EL experiments) and to optimize encapsulation with aluminum frame combined with the factory laboratory. The results show that: the modules have no crack and other defects and their power attenuation does not exceed the specified value after the 2.0mm thickness aluminum frame was reduced to 1.7mm.
