Abstract: Textured transparent layers are formed on the incident light receiving surface of thin film solar cells to increase their efficiency by altering the incident light path and capturing a portion of the light reflected at the MLA. The textured transparent layer is an array of lenses of micrometer proportions such as hemispheres, hemi-ellipsoids, partial-spheres, partial-ellipsoids, cones, pyramids, prisms, half cylinders, or combinations thereof. A method of forming the textured transparent layer to the light incident surface of the solar cell is by forming an array of lenses from a photocurable resin and its subsequent curing. The photocurable resin can be applied by inkjet printing or can be applied by roll to roll imprinting or stamping with a mold.

The miscrolenses are formed on a surface that has been coated to have functionality that promotes a sufficiently large contact angle of the microlense on the surface and contains functionality for bonding the microlense to the coating. The microlenses are formed on the coating by deposition of a microlense precursor resin as a microdrop by inkjet printing and copolymerizing the resin with the bonding functionality in the coating. The coating can be formed from a mixture of silane coupling agents that contain functionality in some of the coupling agents that is copolymeriable with the resin such that the microlens can be formed and bonded to the surface by photopolymerization.
