University of Swansea difused STEELPV results at the WCPC Annual Technical Conference and Exhibition

The university of Swansea has participated, last 9th and 10th November, at the 11th Annual Technical conference organised by WCPC in Swansea. The presentation of Dr. Korochkina was entitled 'Formulation and Deposition of Intermediate Layers on Rough Steel Substrates for Large Area Solar Cells' reporting works carried out in collaboration between the University of Swansea and FundaciĆ³n ITMA.

In this study, a SiOx intermediate layer was created by combining a non-vacuum sol-gel technique developed at ITMA with lab-scale printing and coating techniques developed at WCPC. The SiOx based IL was deposited on non-treated steels such as AISI430 stainless steel, and DX51D bare cold rolled low carbon steel as well as DX51D hot-dip galvanized with Zn or Al which was cold rolled to achieve the desired final thickness. Several batches of sol-gel were prepared for life time tests and printing trials. Results of extensive characterisation of sol-gel solutions and ILs printed onto four steel substrates are reported. We have successfully demonstrated that the SiOx sol-gels have great potential as continuous, defect free insulating IL for development of BIPV systems based on TFSC.
