Perc Solar Cell Manufacturing Process

However from 2013 the industry is changing to the so called perc passivated emitter rear contact structure.

Perc solar cell manufacturing process.

The aluminium back surface field al bsf solar cell has been the working horse for the photovoltaic industry in the recent decades. With the current state of the technology it is possible to achieve up to 1 absolute gain in efficiency. During 2019 production is forecast to exceed 60gw as the dominant technology type deployed by the solar industry for module assembly. 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. In order to create a. 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. Meyer burger offers its customers modular coating systems for the production of perc solar cells.

First a rear surface passivation film is applied. Screen printed silver paste front contact. The schematics of these two solar cells is shown in figure 1. Incorporating perc into a solar cell boosts generation.

Perc solar cell manufacturing. 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 cell an additional two steps are employed to the standard back surface field bsf during the manufacturing process. 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.

In principal incorporating perc into a solar cell boosts generation. Perc technology adds an extra layer to the rear side of a solar cell.
