Perc technology adds an extra layer to the rear side of a solar cell.
Perc solar cell manufacturing process.
The main advantage of the perc cell structure is that it enables manufacturers to achieve higher efficiencies than with standard solar cells which are reaching their physical limits.
In order to create a.
Perc solar cell manufacturing.
Screen printed silver paste front contact.
First a rear surface passivation film is applied.
With the current state of the technology it is possible to achieve up to 1 absolute gain in efficiency.
Back in 2014 p type mono perc cell production was less than 1gw.
Perc which stands for passivated emitter and rear cell or passivated emitter and rear contact is a new technology aimed to achieve higher energy conversion efficiency by adding a dielectric passivation layer on the rear of the cell.
The schematics of these two solar cells is shown in figure 1.
The structure of a perc solar cell from front to rear.
In order to produce a perc cell there are two additional manufacturing steps needed.
Meyer burger offers its customers modular coating systems for the production of perc solar cells.
During 2019 production is forecast to exceed 60gw as the dominant technology type deployed by the solar industry for module assembly.
However from 2013 the industry is changing to the so called perc passivated emitter rear contact structure.
In order to create a perc cell an additional two steps are employed to the standard back surface field bsf during the manufacturing process.
The perc technology passivated emitter rear cell established by meyer burger in the global photovoltaics market represents the mainstream standard in solar cell production today.
The aluminium back surface field al bsf solar cell has been the working horse for the photovoltaic industry in the recent decades.
In principal incorporating perc into a solar cell boosts generation.
