Changing the wafer size and moving to half cut cells was seen as the best option to get to 400wp.
Solar cell wafer size.
However leading mono wafer producer longi green energy technology and major merchant solar cell producers aiko solar and tongwei group started offering 161 75mm x 161 75mm.
It undergoes many microfabrication processes such as doping ion.
At that time our taiwanese cell manufacturer went straight from m2 to the m4 with a size of 161 7 mm in order to only make necessary investment purchases once together with the multi busbar variant.
Tim to 2019 m6 166mm x 166mm p type mono wafers 223mm diameter silicon ingot was lauched.
However several manufacturers had their own ideas on what the larger wafer size should be such.
At the end of q3 2019 longi solar the world s largest mono wafer manufacturer launched another variant on the market for the first time.
In electronics a wafer also called a slice or substrate is a thin slice of semiconductor such as a crystalline silicon c si used for the fabrication of integrated circuits and in photovoltaics to manufacture solar cells the wafer serves as the substrate for microelectronic devices built in and upon the wafer.
Connecting cells in parallel yields a higher current.
Multiple solar cells in an integrated group all oriented in one plane constitute a solar photovoltaic panel or module photovoltaic modules often have a sheet of glass on the sun facing side allowing light to pass while protecting the semiconductor wafers solar cells are usually connected in series creating additive voltage and current.
