Abstract
Solar cells are packaged by placing the solar cells between sheets of encapsulants. The encapsulants are exposed to ultraviolet (UV) light to cure the encapsulants and bond the encapsulants together to encapsulate the solar cells. The UV curing steps may be performed to bond one of the encapsulants to a transparent top cover and the solar cells, and to bond the other encapsulant to the solar cells and a backsheet. A protective package that includes the transparent top cover, encapsulated solar cells, and the backsheet is then optionally mounted on a frame.
Claims20
A method of making a solar cell module, the method comprising:
- placing a first encapsulant on a transparent top cover;
- placing front sides of a plurality of solar cells on the first encapsulant, the front sides of the solar cells facing the sun to collect solar radiation during normal operation;
- and
- curing the first encapsulant to bond the plurality of solar cells to the first encapsulant by exposing the first encapsulant to ultraviolet (UV) light through the transparent top cover.
A method of making a solar cell module, the method comprising:
- placing solar cells between sheets of encapsulants;
- exposing the sheets of encapsulants to ultraviolet (UV) light to bond the sheets of encapsulants together and encapsulate the solar cells;
- placing the encapsulated solar cells on a transparent top cover;
- placing a backsheet on the encapsulated solar cells;
- and
- forming a protective package comprising the transparent top cover, the encapsulated solar cells, and the backsheet.
A method of making a solar cell module. curing a first encapsulant with ultraviolet (UV) light in a first curing step to bond a transparent top cover to the first encapsulant;
- curing the first encapsulant with UV light in a second curing step to bond a plurality of solar cells to the first encapsulant;
- curing a second encapsulant with UV light in a third curing step to bond the first and second encapsulants together and encapsulate the plurality of solar cells;
- and
- mounting a protective package comprising the encapsulated plurality of solar cells, the transparent top cover, and a backsheet onto a frame.
