  • Publication number: 20170338361
    Abstract: A flip-chip multi junction solar cell chip integrated with a bypass diode includes from up to bottom: a glass cover; a transparent bonding layer; a front electrode; an n/p photoelectric conversion layer; a p/n tunnel junction; a structure layer of the n/p bypass diode; a first backside electrode; a second backside electrode. The solar cell chip also includes at least a through hole extending through the n/p photoelectric conversion layer, the p/n tunnel junction and the structure layer of the n/p bypass diode. An ultra-thin substrate-less cell can therefore be provided without occupying effective light receiving areas, greatly improving cell heat dissipation. With a light weight, the chip can also have advantages in space power application.
