Low-cost High-efficiency Solar Module Using Epitaxial Si Thin-film Absorber And Double-sided Heterojunction Solar Cell With Integrated Module Fabrication
One embodiment of the present invention provides a double-sided heterojunction solar cell module. The solar cell includes a frontside glass cover, a backside glass cover situated below the frontside glass cover, and a number of solar cells situated between the frontside glass cover and the backside glass cover. Each solar cell includes a semiconductor multilayer structure situated below the frontside glass cover, including: a frontside electrode grid, a first layer of heavily doped amorphous Si (a-Si) situated below the frontside electrode, a layer of lightly doped crystalline-Si (c-Si) situated below the first layer of heavily doped a-Si, and a layer of heavily doped c-Si situated below the lightly doped c-Si layer. The solar cell also includes a second layer of heavily doped a-Si situated below the multilayer structure; and a backside electrode situated below the second layer of heavily doped a-Si.

- 1. A solar module, comprising:
a first photovoltaic structure; a second photovoltaic structure positioned adjacent to the first photovoltaic structure, wherein each of the first and second photovoltaic structures comprises a first electrode positioned on a first surface and a second electrode positioned on an opposite surface; and wherein a solder tab of the first electrode of the first photovoltaic structure is in direct contact with a solder tab of the second electrode of the second photovoltaic structure, thereby enabling a serial connection between the first and second photovoltaic structures.
- 12. A solar panel, comprising:
a first cover; a second cover; and a plurality of photovoltaic structures positioned between the first and second covers, wherein a respective photovoltaic structure comprises a first electrode positioned on a first surface and a second electrode positioned on an opposite surface of the photovoltaic structure; and wherein the plurality of photovoltaic structures are arranged in a way that a solder tab of the first electrode of a first photovoltaic structure is in direct contact with a solder tab of the second electrode of an adjacent photovoltaic structure, thereby enabling a serial connection between the first photovoltaic structure and the adjacent photovoltaic structure.
