Solar Energy Research Institute Of Singapore Studying Ways To Improve Solar Cell Efficiencies


The Solar Energy Research Institute of Singapore (SERIS) has purchased a process development tool from SoLayTec – a spin-off company of the Dutch research organization Toegepast Natuurwetenschappelijk Onderzoek – that aims to raise the efficiencies of industrial solar cell designs.

Under the contract, SoLayTec's atomic layer deposition (ALD) of aluminum oxide Al2O3 will be applied at a large selection of PV research institutes around the world.

‘The crystalline silicon surface passivation by ALD-grown aluminium oxide films has enabled very high solar cell efficiencies on lab-scale reactors, and we are very excited to see that companies are now bringing ALD from a laboratory scale to a mass production scale,’ says Dr. Bram Hoex, director of the silicon photovoltaics cluster at SERIS." We are confident that our collaboration with SoLayTec will lead to very high efficiencies for large-area silicon wafer solar cells, for several solar cell designs under development at SERIS."

SERIS, metalorganics material supplier AkzoNobel and SoLayTec also have a three-year contract to research the integration of Al2O3 into new cell concepts.

According to the organizations, the contract with SERIS will allow SoLayTec more access to the Asian market.

"At this moment, we do the sampling for our Asian customers in our European headquarters," says Roger Gortzen, co-founder and marketing and sales manager at SoLayTec." After the installation of our process development tool at SERIS, which is fully equipped for the pilot-scale production of solar cells, we are able to accelerate research and demonstrate our technology to our customers in Asia."
