Abstract: When dealing with building integrated photovoltaics aesthetical aspects have to be considered. In particular for façade integrated modules with crystalline Silicon (c-Si) solar cells alternative colors are demanded. In this paper an approach for tuning the color of standard c-Si solar cells is presented relying on plasmonic coloring. Metallic (Ag) nano-particles with a diameter of around 100 nm were created on the surface of standard c-Si solar cells. At those nano-particles plasmonic scattering at around 450 to 550 nm causes a color change from blue to green. The green color is resulting from plasmonic scattering and it is found to be insensitive to the angle of observation. A performance analysis of the c-Si cells before and after coating shows that the power of the cells is decreased by less than 10% when applying the plasmonic coating. A first test module comprising of plasmonic-green c-Si cells was carefully characterized and mounted at a test façade for building integrated modules in order to generate data in the targeted field of application. First results of the test module demonstrate that plasmonic coloring is a feasible approach to tune the color of standard c-Si solar cells for being applied in building integrated photovoltaics.
