Abstract
Various combinations of a first encapsulant and a second encapsulant on different locations of a photovoltaic module are used to meet various requirements of optical clarity, tensile strength, waterproofness, and resistivity.
Claims13
An encapsulation of a photovoltaic module, comprising:
- a first encapsulant covering a photovoltaic cell array on a front substrate, wherein the first encapsulant has good optical clarity and moderate tensile strength;
- and
- a second encapsulant covering peripheral part of the front substrate, wherein the peripheral part surrounds the photovoltaic cell array, wherein the second encapsulant has good waterproofness and resistivity, and wherein the second encapsulant does not contain desiccant material.
A photovoltaic module, comprising:
- a front substrate;
- a photovoltaic cell array on the front substrate;
- a first encapsulant covering the photovoltaic cell array, wherein the first encapsulant has good optical clarity and moderate tensile strength;
- a second encapsulant covering peripheral part of the front substrate, wherein the peripheral part surrounds the photovoltaic cell array, wherein the second encapsulant has good waterproofness and resistivity, and wherein the second encapsulant does not contain desiccant material;
- and
- a back substrate covering the first encapsulant and the second encapsulant.
