Perc Solar Cell Manufacturing Process

The schematics of these two solar cells is shown in figure 1.

Perc solar cell manufacturing process.

First a rear surface passivation film is applied. In order to create a. One of the biggest reasons why perc technology can be so powerful is the minimal investment it takes to begin manufacturing perc solar cells instead of standard monocrystalline solar cells. The structure of a perc solar cell from front to rear.

Screen printed silver paste front contact. Back in 2014 p type mono perc cell production was less than 1gw. In order to create a perc cell an additional two steps are employed to the standard back surface field bsf during the manufacturing process. During 2019 production is forecast to exceed 60gw as the dominant technology type deployed by the solar industry for module assembly.

In order to produce a perc cell there are two additional manufacturing steps needed. 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. Perc technology adds an extra layer to the rear side of a solar cell. The aluminium back surface field al bsf solar cell has been the working horse for the photovoltaic industry in the recent decades.

Perc solar cell manufacturing. Meyer burger offers its customers modular coating systems for the production of perc solar cells. 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. With the current state of the technology it is possible to achieve up to 1 absolute gain in efficiency.

In principal incorporating perc into a solar cell boosts generation. Most of the research on solar cells was done focusing on the front side of a solar cell and less attention was paid to taking advantage of production opportunities from the backside.
