Package structure of concentrated photovoltaic cell

摘要

A package structure of a concentrated photovoltaic cell includes a ceramic base plate whereon a cavity is formed, the cavity having two opposite internal walls respectively having staircase structures, each having an upper step and a lower step; a photovoltaic chip disposed on a bottom surface of the cavity; a first electrode circuit path penetrating the ceramic base plate and with a top end electrically connected to the photovoltaic chip; a second electrode circuit path penetrating the lower steps on the two sides of the ceramic base plate and connecting with the photovoltaic cell through metal wires; and a transparent cover disposed on the upper steps for covering the cavity and the photovoltaic chip. A fabrication method for the aforementioned package structure is also provided. The aforementioned package structure has the advantages of being more efficient in heat dissipation and effective in protecting the photovoltaic chip.
