Abstract
A bifacial photovoltaic module has components that are arranged to maximize the efficiency of a module for both front and back surfaces. An opaque portion is disposed on back surfaces of modules and aligned with horizontal support bars of a multiple-module system. Junction boxes are arranged at opposing ends of the opaque portion and couple adjacent modules in the system.
Claims20
An apparatus comprising:
- a first string comprising a first plurality of overlapping strips of photovoltaic material connected in series, each of the first plurality of overlapping strips comprising,
- a first conductive finger located on a front side,
- a first front side bus bar in communication with the first conductive finger,
- a second conductive finger located on a back side, and
- a first back side bus bar in communication with the second conductive finger;
- a second string comprising a second plurality of overlapping strips of the photovoltaic material connected in series, each of the second plurality of overlapping strips comprising,
- a third conductive finger located on a front side,
- a second side bus bar in communication with the third conductive finger,
- a fourth conductive finger located on a back side, and
- a second back side bus bar in communication with the fourth conductive finger;
- a first zone comprising the first string and the second string connected in parallel;
- and
- a bypass diode structure in dedicated electrical communication with the first zone and configured to compensate for uneven illumination of the back side of the first string relative to the back side of the second string.

A method comprising:
- exposing a back side of a first string comprising a first plurality of overlapping strips of photovoltaic material connected in series, to light having a first intensity;
- exposing a back side of a second string comprising a second plurality of overlapping strips of photovoltaic material connected in series, to light having a second intensity relative to the first intensity;
- and
- connecting in parallel across a single bypass diode structure, electrically conductive material of the back side of the first string, with electrically conductive material on the back side of the second string,
- wherein the single bypass diode structure serves to protect against uneven currents arising from differences between the first light intensity and the second light intensity.
