1. Overview of the current situation of photovoltaic cell technology: efficiency improvement and cost reduction is an eternal topic for the development of the photovoltaic industry, and in many links of the industrial chain, the solar cell is the core of technological progress and determines the eff...
Read MoreSilicon solar cells can generally be divided into monocrystalline, polycrystalline and amorphous silicon solar cells, of which monocrystalline silicon cells are currently the fastest developed solar cells, its structure and production process has been finalized, and is widely used in space and groun...
Read MoreWith the continuous improvement of the yield rate of the photovoltaic module market, the quality requirements of solar cells in photovoltaic modules are also increasing with the increase of their yield rate, but the passivation of the surface of solar panels is often deteriorated due to the PID effe...
Read MoreSince the performance or output power stability of amorphous silicon solar cells is often affected by various factors in practical application, solar cell manufacturers often try their best to improve the stability of amorphous silicon solar cell performance. Stability of amorphous silicon solar cel...
Read MoreDuring cell production, the thermal diffusion process often affects numerous factors in the performance of TOPCon solar cells, resulting in changes in cell performance. In order to scientifically evaluate the degree of influence of the thermal diffusion process on the performance of TOPCon solar cel...
Read MoreHJT, short for Heterojunction Technology, is an N-type monocrystalline bifacial cell with the advantages of simple process, high power generation and low cost of electricity. HIT (Heterojunction with Intrinsic Thin layer) has been registered as a trademark by Sanyo Corporation of Japan, so it is als...
Read MoreCompared to conventional solar cells, interdigitated back contact (IBC) solar cells have several special features, including back contact points and back contact, so they are not subject to the shading loss of the front metal grid. Since there is no frontal grid, the light is brighter and the series...
Read MorePL showed that the pitting appeared after diffusion, which was greatly reduced after etching and cleaning, and the proportion of pitting after oxidation increased significantly, reaching more than 95%. Suspicions: 1. Oxidation will amplify the pitting produced in the front section; 2. Pockma...
Read MoreThis study solves the question of how the doped amorphous silicon layer in silicon heterojunction solar cells treated with hydrofluoric acid (HF) affects their performance. It was found that low concentrations (2.5-5.0%) of HF solutions had different effects on n-type and p-type amorphous silicon la...
Read MoreScientists have developed a technique for producing AZO and i-ZnO/AZO bilayer structures in solar cells that greatly improves cell efficiency and durability. Using a low power deposition method that avoids raising the substrate temperature, the team achieved a power conversion efficiency of 9.53% wi...
Read More(1) Texturing Raw material silicon wafer in the cutting process will form about 10 ~ 15 μm thick damage layer on the surface, this layer because of the state of the silicon wafer matrix has been different, basically has been peeled off to the matrix, will seriously affect the performance of solar...
Read More1. HPBC solar cell technology HPBC-Hybrid Passivated Back Contact is a new generation of high-efficiency solar cell technology characterized by no grid on the front of the solar cell. HPBC solar cell vs. PERC solar cell (1) The solar cell technology combines two advanced solar...
