The CISSY integrated system

CISSY - enlarged view

Fig. 1: CISSY system including sputtering, analytics, preparation, surface photovoltage (SPV) setup and MBE chambers. A glove box is used for handling the samples.

In the CISSY ultrahigh vacuum system, some of the crucial steps of the preparation of thin film solar cells can be performed in-system, allowing the direct transfer from preparation to the analysis chamber, avoiding contamination. Magnetron sputtering (for transparent window layers or buffer layers) is possible in a separate chamber and various wet chemical treatment or deposition methods are available inside an attached glove box. Evaporation of alkali metals and alkali fluorides are done in another separate chamber. Sample characterization is possible using surface sensitive x-ray and ultraviolet photo electron spectroscopy (XPS, UPS). In addition, surface photovoltage spectroscopy (SPV) is available [1].
