NOVELTY - The method involves performing first annealing process on a solar cell (12) for transforming an adhered powder layer in a pre-annealed coating layer to create a coated solar cell. Open contacting areas (14) are created on the solar cell by removal of the adhered powder layer at locations of contacting areas on the solar cell. The open contacting areas are created on the solar cell by masking contacting areas on the solar cell to prevent coverage by the adhered powder layer and to create open contacting areas on the solar cell, where masking precedes deposition step or deposition steps.    USE - Method for manufacturing a solar cell module for a solar panel in a solar cell or solar panel processing line (all claimed).    ADVANTAGE - The method enables providing a pre-annealed coating layer with a structure of channels that allows removal of gases during later solar panel lamination process under vacuum. The method ensures that porosity of the pre-annealed coating layer during manufacturing of a solar panel stack in which solar cells provided with porous pre-annealed coating layers are laminated. The method enables reducing time required for degassing or outgassing and preventing inclusion of gas within a solar panel stack. The method enables using powder coating technique to create coating layers that are relatively thin, which reduces weight of the solar panel to be produced. The method ensures that amount of contacting material that needs to be applied in openings of the pre-annealed coating layer reduces proportionately with reduced thickness of the pre-annealed coating layer, which saves on amount of contacting material needed and costs. The method enables using material to facilitate easy release of the pre-annealed coating layer from the support layer.
