    Double glazing for encapsulating solar cells

    Hi All,

    Not sure if this has been discussed here ...
    I am in the UK, double glazing windows and doors are now wide spread here and the technology to make sealed units is well established,
    me thinking aloud ... why can we not adapt such simpler methods to encapsulate solar cells, it will be lot cheaper, quicker and longer lasting???

    I was at a sealed unit factory yesterday, they demo'ed the way they make the unit: two sheets of glass on top of each other with spacer in between,
    the unit is sealed with hot melt then two holes are drilled to fill it with Argon gas and that is it,

    I am aware that the solar cells [poly/mono 156x156mm] are thin something like 200 to 300micrometer, surely - the cells can be tabbed the usual way and placed in between the glass sheets and sealed as above.
    Obviously the hot melt material will be different to cope with higher temperatures and other out door harsh elements.

    can someone in the knowhow of either industries tell me why this won't work?

    thanks

    What would be the point with PV cells?

    Windows are made double panel to decrease heat loss. You what PV cells to lose heat as they are more efficient at cooler temps.

    Solar cells are encapsulated between a layer of glass on top and a plastic or poly layer on the bottom. With no air space left no need for argon or any other gas. No need for it either as it's added as an insulator to increase the r-value of the window/

      For openers, just what is going to keep the cells of my 6 X 12 array in their proper vertical position? The whole mess will start
      sliding down hill and short out and/or break. If you glue them to one side first, you are starting to use accepted practice.
