Solar package structure and method for fabricating the same

Abstract

The invention provides a solar package structure and a method for fabricating the same. A solar package structure includes a carrier wafer. A conductive pattern layer is disposed on the carrier wafer. A solar cell chip array is disposed on the conductive pattern layer, wherein the solar cell chip array electrically connects to the conductive pattern layer. A first spacer dam is disposed on the carrier wafer, surrounding the solar cell chip array. A first optical element array is disposed over the carrier wafer to concentrate sunbeams onto the solar cell chip array, wherein the first optical element array is spaced apart from the carrier wafer by the first spacer dam.

Description

Technical field [0001] The invention relates to a solar cell packaging structure and a manufacturing method thereof, in particular to a solar cell packaging structure using a wafer level packaging process and a manufacturing method thereof. Background technique [0002] A solar cell is a device that directly converts solar energy into electrical energy by using the photovoltaic effect (photovoltaic effect). The size and weight of known solar cells are respectively limited by the huge size of 10cm x 10cm x 10-20cm and the bulky module weight of 4 kilograms (kg). The lens of the known solar cell focuses sunlight only on a single solar chip. Therefore, when the temperature of the known solar cell increases, the heat from the known solar cell will be slowly dissipated to the outside. Therefore, it is necessary to use a heat sink to improve the heat dissipation efficiency. However, the conventional solar cell increases its module weight due to the additional heat sink. At the same...
