AGPRO has the independently developed powder and formulae that offers adjustable particle sizes and distribution. The height (affects incident light level) and width (affects incident light surface area) of the grating affect the quality of the solar cell. The pastes’ solid content, the particle deposition technology and grating height/width feature innovations that are very competitive on the international market. By introducing nano-level colloidal silver into the silver paste, the conductor density is increased. Moreover sintering temperature is reduced and coating quality is improved.[The 14th Taiwan SMEs Innovation Award]
