(SE200901339-A1)   NOVELTY - The method involves connecting a photovoltaic unit between two glass sheets (2). The photovoltaic unit is electrically connected to solar cells (1) and an electrical network, where the cells are made of inorganic material. A glass plate (11) is superimposed for covering another glass plate (5). The distance between the glass plates is about 0.5-2 mm. Outer edges of the glass plates are covered with a glass band and / or glass fibers. The outer edges and the glass band and/or glass fibers are heated by heat source, and melted together for hermetically forming a seal around an enclosed space.    USE - Method for encapsulating crystalline solar cells in a vehicle.    ADVANTAGE - The method enables replacing the solar cells in inexpensive manner. The method enables the glass sheets to seal an edge of solar cells area, so as to protect the solar cells from moisture and damage, thus prolonging service life of the solar cells. The method enables reducing pressure, size and occupied area of the solar cells.    DETAILED DESCRIPTION - Enclosing solar cells (1) e.g. made of crystal form or as thin film, between at least two sheet units, preferably two glass sheets (2) included in e.g. a solar catcher (3) the solar cells (1) are electrically connectable in order to conduct current out from these and further to other solar cells (1) and/or to an electrical network, the method comprises in a first step the solar cells (1) are arranged at a first glass sheet (5) whereupon a second glass sheet (11) is laid on top of the first one in order to cover the same in a second step and be distanced along its circumference (6) along its edge area (4) by aid of a at least one spacer (9), which creates a distance (7) between the glass sheets (5, 11) of 0.5-2 mm, the outermost edges (8) of which and the distance (7) in a third step are covered by at least a portion of an elongated side area of a glass strip (17) and/or a glass fiber (10), the side surface is applied along the outermost edges (8) around the circumference (6), whereupon in a fourth step at least the outermost edges (8) and the glass strip/glass fiber (17, 10) are heated by at least one heating source until they have been melted together to a seal (22) around a hermetically enclosed space (19).
