  • the present invention relates to use of calcium oxide as a water scavenger in edge sealant formulations for solar modules.
  • Photovoltaic solar panels or modules generally include a photovoltaic device that is laminated and/or sandwiched between a plurality of layers.
  • the majority of photovoltaic devices are rigid wafer-based crystalline silicon cells or thin film modules having cadmium telluride (Cd-Te), amorphous silicon, or copper-indium-diselenide (CulnSe 2 ) deposited on a substrate.
  • the thin film solar modules may be either rigid or flexible. Flexible thin film cells and modules are created by depositing the photoactive layer and any other necessary substance on a flexible substrate. Photovoltaic devices are connected electrically to one another and to other solar panels or modules to form an integrated system.
  • edge sealants have the property of having a low rate of moisture vapor transmission, or MVT.
  • An additional method for reducing the rate of moisture transmission is through use of a desiccant material.
  • a desiccant material is molecular sieves.
  • Molecular sieves are comprised of materials containing tiny pores of a precise and uniform size that are used as an adsorbent. Molecules of water are small enough to pass through the pores and are adsorbed within the molecular sieve material.

  • water scavengers Another class of materials that can remove moisture from surroundings include water scavengers. Unlike standard desiccants, water scavengers react with water in a manner that is not reversible under the conditions that the product experiences in its normal lifetime. However, water scavengers are caustic compounds that are corrosive. Accordingly, water scavengers have not been used in solar module applications due to the caustic nature of the compound. Therefore, there is a need in the art for a sealant in solar modules that incorporates a water scavenger that does not release water and that does not corrode the sealant over the lifetime of the solar module and that provides improved water absorption over desiccant materials.

  • Calcium oxide reacts with water to form calcium hydroxide, according to the equation:
  • the calcium oxide adsorbs a much greater amount of water vapor at a very low relative humidity than other materials. Calcium oxide is most effective where a low critical relative humidity is necessary, and where there is a high concentration of water vapor present. Calcium oxide removes water from the environment very slowly, often taking days to reach its maximum capacity. In addition, calcium oxide has a low water capacity at room temperature and humidity. As the calcium oxide adsorbs moisture, it swells. Accordingly, the sealant composition must have balanced properties to account for any swelling during use. The properties are balanced by, for example, adjusting the amount of calcium oxide in the composition.
  • the density of calcium oxide is 3.25-3.38 g/mL, and the density of calcium hydroxide is 2.24 g/mL, according to the CRC Handbook of Chemistry and Physics, 60 th edition. Therefore, theoretically, there is a limit as to how much calcium oxide may be incorporated into an edge sealant formulation. However, no difficulties have been observed over the incorporation range tested.
  • FIGS. 3 and 4 show the break through times associated with use of calcium oxide over molecular sieves. Break through time is the amount of time it takes to reach 5% of the steady state MVTR value after the initial 90 hour predrying phase is complete. As seen by FIG. 3, the breakthrough time for the composition containing calcium oxide is about 9 hours and the break through time for the composition containing the molecular sieve shown in FIG. 4 is about 20 hours.
  • Calcium oxide is corrosive and can theoretically react with other components within an edge seal and within a solar module. However, within edge seals in solar modules with the present composition, no corrosive effects manifest. [0046] In addition, calcium oxide can be combined with molecular sieves to further increase the moisture trapping ability of the edge sealant.
