Perc Solar Cell Manufacturing Process

Perc solar cell manufacturing.

Perc solar cell manufacturing process.

Incorporating perc into a solar cell boosts generation. With the current state of the technology it is possible to achieve up to 1 absolute gain in efficiency. Screen printed silver paste front contact. The structure of a perc solar cell from front to rear.

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. The schematics of these two solar cells is shown in figure 1. 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. Meyer burger offers its customers modular coating systems for the production of perc solar cells.

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. In order to create a. Perc technology adds an extra layer to the rear side of a solar cell. In order to produce a perc cell there are two additional manufacturing steps needed.

Back in 2014 p type mono perc cell production was less than 1gw. First a rear surface passivation film is applied. 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.

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.
