Perc Solar Cell Manufacturing Process

During 2019 production is forecast to exceed 60gw as the dominant technology type deployed by the solar industry for module assembly.

Perc solar cell manufacturing process.

With the current state of the technology it is possible to achieve up to 1 absolute gain in efficiency. 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. 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. First a rear surface passivation film is applied.

However from 2013 the industry is changing to the so called perc passivated emitter rear contact structure. Back in 2014 p type mono perc cell production was less than 1gw. 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 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 cell an additional two steps are employed to the standard back surface field bsf during the manufacturing process. In order to produce a perc cell there are two additional manufacturing steps needed. Perc solar cell manufacturing. The schematics of these two solar cells is shown in figure 1.

Incorporating perc into a solar cell boosts generation. Perc technology adds an extra layer to the rear side of a solar cell. In order to create a. Meyer burger offers its customers modular coating systems for the production of perc solar cells.

The structure of a perc solar cell from front to rear. 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.
