Perovskite and CIGS materials are well-suited for fabricating highly efficient thin film solar cells and modules. For both materials the correct process sequence is crucial to initiate the appropriate reaction paths leading to the optimum layer properties and device performance. In-situ metrology by means of reflectance spectroscopy constitutes a very powerful technique for monitoring a large variety of deposition and film formation techniques such as spin-coating, annealing or co-evaporation. In this poster, an overview about recent results obtained for perovskite spin-coating and CIGS evaporation are presented.
