The hole collector in silicon heterojunction cells serves not only as an integral component of the/junction, determining the strength of the built-in electric field, but also as a layer responsible for hole transport, thereby affecting carrier transport capacity. To enhance carrier extraction and transport properties of the hole collector, various interface treatments have been employed on-type nanocrystalline (-nc-Si:H) hole collectors. Through an examination of characteristics such as dark conductivity, crystallinity, and contact resistance, the impact of interface treatment on-nc-Si:H hole collectors is clarified.

The influence of parameters, such as the concentration of sodium alginate (SA), chitosan (CTS), CaCl, clam heparinoid DG1, and curcumin (Cur), on the characteristics of the nanoparticles, were investigated. Results indicate that chitosan and alginate can be used as polymer matrices to encapsulate DG1, and nanoparticle characteristics depend on the preparation parameters.

The results showed that sludge hydrolysis, SCFA accumulation, NH(4)(+)-N and PO(4)(3-)-P release, and volatile suspended solids (VSS) reduction were increased by WAS addition to PS, which were further increased by the addition of SDBS to the mixture of PS and WAS. Acetic, propionic and valeric acids were the top three SCFA in all experiments.
