Abstract: In accordance with one or more embodiments herein, a method of manufacturing a photovoltaic (PV) top module, to be used together with a PV bottom module, e.g. an SI-based PV bottom module, is provided. The method may include monolithically interconnecting a plurality of thin film based PV sub-cells, manufactured using a perovskite material and/or a CIGS material as solar absorbing material, in series on a substrate in order to create a PV top module including at least one first PV top sub-module, and arranging metal grid lines on top and bottom contact layers of the PV top module. The metal grid lines may be arranged either above or below the top and bottom contact layers of the PV top module.
