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...

How to convert solar cell area/efficiency?   Monocrystalline silicon wafer area   The shape of the single crystal solar cell is generated by cutting a cylindrical silicon rod formed using the cinetol method. The calculation idea of the area of the monocrystalline silicon wafer is derived f...

The next generation of photovoltaic mainstream technology Compared to those solar cell manufacturing that have more than 10 steps of processing, HJT cells only need 4 steps, all at low temperatures. The streamlined process effectively reduces production costs and carbon emissions and is more in...

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...

Key conclusion The tunnel oxide layer prepared by PE method has an optimal film thickness, and the film quality of the tunnel layer is directly related to the concentration of O atoms excited by plasma The degree of internal expansion of n-poly Si has an optimal range for passivation and contact pr...
