Since 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...

During 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...

HJT, 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...

Compared 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...

PL 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...

Definition Sheet resistance Refers to the resistance of a semiconductor film or a metal film per unit area Sheet resistance is only related to film thickness and material properties     R-resistance -Ω, ρ- resistivity Ω.cm, L-length -cm, S- area -cm² Rs=ρ/d Rs-s...

This 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...

Luminescent imaging The basic principle of luminous imaging is to excite the surface of a sample to make it glow, and then capture the luminous image with a camera. Two imaging methods are commonly used in crystalline silicon solar cells PL, Photo-luminescence, photoluminescence, excitation by incid...

Scientists 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...

(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...

1. 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...

BC type solar cells, that is, Back Contact solar cells, is a general term for various types of back-contact structural crystalline silicon solar cells, mainly including IBC, HBC (HJT+IBC), TBC (TOPCon+IBC), HPBC, etc. There is no grid line on the front surface of the solar cell, and the positive and...
