Summary

The UNSW School of Photovoltaic and Renewable Energy Engineering has received a funding grant from ARENA to conduct a research and development project which address the performance and cost limitations of current PERC technology by transformation into PERL technology for industrial environments by incorporating multiple separately proven technologies.

Hydrogen passivation will be used to neutralise defects in the silicon material and laser doping and bifacial plating will be used for a low-cost implementation of a PERL structure.

How the project works

The Hydrogenated Bifacial PERL Silicon PV Cells project is a key initiative of ARENA’s 2017 Investment Plan for accelerating solar PV innovation. The project will combine three separate technologies that were developed in previous ARENA projects. The study will integrate hydrogen passivation, laser doping and bifacial plating into the current PERC solar cell technology to overcome performance limitations and reduce cost.

One of the key outcomes for the project is to develop an industrial PERL technology to increase cell efficiencies to over 24%.

Area of innovation

The Hydrogenated Bifacial PERL Silicon PV Cells project will integrate three innovative technologies into the current PERC solar cell process to develop the next generation high-efficiency solar cell technology for commercial production. Laser doping will allow the formation of localised heavily doped regions for the PERL structure. Bifacial plating will reduce cost of metal deposition and enable the generation of current from both front and rear surfaces of the cell. The advanced hydrogenation technology will eliminate light induced degradation and improve stability of the solar cells.

Benefit

The project will generate new knowledge on the development of high-efficiency p-type solar cells using innovative, high-throughput commercial production processes and equipment. This will increase the efficiency and reduce the cost of industrial p-type solar cells and generate new intellectual property.
