Mitsubishi Electric manufactures high efficiency PV cells

Solar power is a clean way to generate electricity that’s not only environmentally friendly, but economical. photovoltaic modules that gather energy from the sun, and release it as electricity that can power home or office to save on energy costs while helping protect the planet and to bring clean, reliable energy to residences, business, power-generation plants, schools, factories and areas without access to electricity, as well as other applications such highway and stadium lighting.
Photovoltaic modules manufactured by Mitsubishi Electric’s utilize polysilicon technology which is known for their high reliability, high-efficiency, and low environmental impact with 25-year limited warranty on power output.Solar cells have separate connecting tab wiring between the front and back sides. This is an effective step toward optimization of connecting conditions, while curving cell warp to support the move toward thinner solar cells.For the silver electrodes formed on the solar cell surface, an exclusive composition and manufacturing process is used by them that excel in environmental resistance and introduced industry-first introduction of mass-produced “solder-coatingless cells”. This removes lead (traditional lead-solder modules use about 860 grams of lead) which is harmful to the human body, while the expanded light reflection effects with the solderless status improve cell efficiency. Mitsubishi Electric has developed fine grid electrodes with an optimal BSF structure and use of anti-reflective coating for the solar cell manufacturing process which has expanded the solar cell light receiving area to realize high-efficiency cells.Solar cell string pitch have been expanded and the high reflectance back film reflects light to raise module efficiency.Use of glass that is cerium-free and high in transmittance has defined a new dimension in high efficiency, free of initial deterioration.
