General Introduction As the manufacturing level of PV module industry is continuously improving, each module enterprise wants to pursue higher quality products. First of all, high quality raw material squares should be selected to ensure the quality of the modules. And there are only three aspects that really have a key impact on the intrinsic … Read more
Preface The photovoltaic module is the smallest PV cell assembly device with a package and internal connection, which can provide DC power individually and cannot be divided. It is the core component of a photovoltaic power generation system, composed of eight core materials. Then today let’s go into the ambitious photovoltaic, together to understand the … Read more
Preface We all know that PV module is an important part of PV power system and the cost of the module accounts for half of the cost of PV system. However, how much do you know about the work of PV modules, their composition, production, calculation of efficiency and related parameters? Today let me introduce … Read more
1. N-PERT ①This is a typical double-sided cell. A bifacial solar cell is a solar cell that can receive light and generate photogenerated voltage and current on both the front and the reverse side of the silicon wafer. It is an improved version of P-PERC technology. ②N-PERT can achieve mass production with easy technical difficulty … Read more
1. 182mm wafer VS 210mm wafer Advantages of 210 silicon wafers: ①The increasing size of silicon wafers can bring about cost reduction and efficiency gains in many aspects of the downstream process. Large wafer cost reduction mainly comes from the “flux” and “inconsistent area perimeter increase” cost reduction effect. Flux: the capacity increases when the … Read more
1. Photovoltaic modules: the foundation of solar power generation Solar cell module = solar panel:Due to the low output voltage of a single solar cell, coupled with the unencapsulated cells due to the environmental impact of the electrodes are easily fall off. Therefore, a certain number of single cells must be sealed into by using … Read more
1. Brief introduction of PV ribbon Photovoltaic ribbon, also known as tinned copper tape or tinned copper tape/sub-connector tape/interconnector ribbon. The conventional size of PV ribbon is generally: 1-6mm wide, 0.08-0.5mm thick, with a 10-30um thick flux coating. We usually use it for the connection between PV module cells. The PV cell wafer connected by … Read more
1. The role of PV Ribbon PV Ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the tabbing wire will directly affect the collection efficiency of the PV module current. It has a great impact on the power of the PV module. The welding tape must be firmly … Read more
PV ribbon performance indicators are all important in their own right. The type of copper and its purity determine the electrical conductivity of the material and the maximum degree of flexibility that can be achieved with the ribbon. 1. Innovations in photovoltaic ribbon substrates Raytron is original in using CCA instead of copper as the … Read more
1. The impact of photovoltaic ribbon on the module PV ribbon is an important component of every mainstream solar panel. It is used to interconnect solar cells and provide connections to junction boxes. PV ribbon is tinned copper tape, 1-6mm wide, 0.08-0.5mm thick, with a 10-30um thick flux coating. PV ribbons are used on PV … Read more
