What do "M" and "G" stand for in solar wafer size?   It begins with the letter "G", which means that the solar silicon wafer is full square Beginning with the letter "M", it means that the solar silicon wafer is Pseudo-square and has chamfer.   EG：     As an important link in t...

Solar Cell Size The core of photovoltaic solar panels is solar cells, divided into single-crystal solar cells and polycrystalline solar cells, due to the bottleneck of efficiency, the market share of polycrystalline solar cells is becoming less and less, and currently single-crystal solar cells are...

In the photovoltaic field, solar cell technology is always a decisive factor in module performance, concerning not only the photovoltaic conversion efficiency but also directly determining the manufacturing cost.  Currently, as research continues to advance, the five mainstream technologie...

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...

Solar energy as the future energy is concerned, in the next generation of products of several BC cells(HPBC, TBC, HBC), HPBC is a direction of the development of solar cell technology. HPBC cell combine the benefits of passivated emitter and back surface passivated contact technology (PERC) and adop...

Tandem solar cells are a type of solar cell that combines two or more different photovoltaic materials in a single device. This allows tandem cells to capture a wider range of the solar spectrum and generate more electricity than single-junction cells. One promising combination for tandem solar cell...
