Method for packaging solar cell receiver having secondary optical elements

A method for packaging solar cell receiver having secondary optical elements, comprising steps of:

• injecting optical encapsulant into a mold, said mold having at least a mold cavity, said mold cavity recessed on the inner surface of said mold, and said optical encapsulant filling said mold cavity;
• placing a substrate upside down towards said mold, at least a solar cell mounted on upside of said substrate, said solar cell corresponding to said mold cavity and immersed downwards in said optical encapsulant;
• curing said optical encapsulant, and sealing said solar cell in said cured optical encapsulant;
• and
• removing said mold, and forming said solar cell receiver;
• wherein said optical encapsulant forms said secondary optical elements in said mold cavity so that the incident light can be focused by said secondary optical element and increasing optical alignment tolerance.
