The solar cell module of this invention reduces water reaching to a front surface glass in using a rear surface member of a resin film so as to suppress sodium deposited from the front surface glass from reaching to the front surface of the solar cell element. The solar cell module of this invention comprises a front surface glass, a rear surface resin film, a plurality of solar cell elements sealed with sealing resin between the front surface glass and the rear surface resin film, and a water transmission preventing layer arranged in a position including at least an interval part between the solar cell elements adjacent each other.

Solar cell module

A solar cell module including a plurality of solar cell elements sealed by EVA resin between a front surface glass and a rear surface member is provided with a sodium diffusion preventing layer of a PET film of a smaller water vapor transmission rate than those of the EVA sheets interposed between the front surface glass and the solar cell elements

A plurality of solar cell groups having a plurality of solar cells connected to each other electrically in serial. A plurality of diodes are connected to each of the solar cell groups electrically in parallel. The plurality of diodes are sealed between transmissive front surface members and transmissive rear surface members together with the plurality of solar cell groups.

Solar cell module for preventing reverse voltage to solar cells

A method of manufacturing a photovoltaic device includes the steps of: preparing a plurality of photovoltaic elements each including an insulator film, a first electrode, an amorphous semiconductor film for photoelectric conversion and a second electrode stacked in this order on a supporting substrate; electrically connecting the photovoltaic elements with each other; attaching a common protection film onto the second electrodes of the photovoltaic elements; and removing the supporting substrate from the photovoltaic elements, wherein the protection film mechanically couples the plurality of photovoltaic elements with each other.
