In this work a photovoltaic mini-module combining interdigitated back contacted solar cells with black silicon in the front was implemented as a proof of concept. The module consists of nine solar cells connected in series with an active area of 86.5 cm2. Both the assembly and panel encapsulation were made using industrial back contact module technology. Noticeable photovoltaic efficiencies of 18.1% and 19.9% of the whole module and the best individual cell of the module respectively, demonstrate that fragile nanostructures can withstand standard module fabrication stages. Open circuit voltage and fill factor values of 5.76 V and 81.6% respectively reveal that series interconnection between cells works as expected, confirming a good ohmic contact between cell busbars and the conductive back sheet. Additionally, the excellent quasi-omnidirectional anti-reflection properties of black silicon surfaces prevails at module-level, as it is corroborated by light incidence angle dependence measurements of the short circuit current parameter.
