IBChampion, High efficiency IBC cell and module technology in the Netherlands

Publieke samenvatting / Public summary

The growth of the PV market has been spectacular in the last years. At the same time a significant shift occurred in production location from Europe to Asia while equipment manufacturing has largely remained in Europe. Dutch equipment manufacturers need to realize and maintain a strong position in the Photovoltaic sector.

The goal of this project is the development of a high-efficiency Interdigitated Back Contact (IBC) solar cel. The targeted efficiency of the cell is 22-23% based on a 6 inch wafer.

Korte omschrijving
In this project the consortium led by Levitech B.V. will develop a high-efficiency Interdigitated Back Contact (IBC) solar cell as a natural up-grade of the n-PASHA solar cell. With this cell, the consortium aims to demonstrate the feasibility of a full-sized module with a 20.5 – 21.5% full-area module efficiency. The project is organised in several work packages (WPs) of which WP 1 and WP2 will be responsible for the main deliverables of cell and module respectively. These WP's will integrate the passivation, doping, metallization and patterning processes developed in the WP 3 to 7.

The project results in a low-cost IBC cell concept based on ECN patents which features wide contact regions for both polarities without loss in cell performance and therefore making easy module integration possible. The result will be achieved with a process that only adds 1 to 4 extra steps to the already commercialized n-PASHA process.
