TU Delft

The Photovoltaic Materials and Devices group at Delft University of Technology works on the photovoltaic value chain from the study and optimization of heterointerfaces at atomistic scale up to the modelling of custom PV modules and systems at kilometer scale. The group has several facilities in clean room environment and cutting-edge laboratories to realize its mission to deploy X-Integrated PV systems providing green electricity for the sustainable electrification of society.

The PVMD group has recently developed several opto-electrical strategies to boost the efficiency of sustainable crystalline silicon (c-Si) heterojunction solar cells. Its expertise in (i) passivating nano-roughness for excellent light in-coupling, (ii) achieving record high efficiency in c-Si solar cells endowed with transition metal oxides (TMOs), (iii) executing Cu-based metallization schemes on ultra-thin transparent conductive oxides (TCOs), and (iv) environmental impact of photovoltaic technologies make a perfect fit for SiLEAN project.

The PVMD group will contribute to the upscaling of TMO- and Cu-based front/back-contacted silicon heterojunction solar cells manufactured with ultra-thin TCOs on thin c-Si wafers. At the same time, it will lead the study on the environmental impact of the solar cell and module technology developed in SiLEAN project.
