| Title: | LIGHT CAPTURE WITH PATTERNED SOLAR CELL BUS WIRES | |||||||||||
| Abstract: | Crystalline silicon PV modules typically use tinned flat copper wire to increase the conductivity of a bus bar metallization and to interconnect to adjacent cells. Such a flat bus wire may be patterned with shallow v-shaped grooves using metal forming techniques, such as rolling, stamping and drawing. The grooves are designed so that incident light is reflected up toward the glass superstrate of t module at an internal interface angle that is large enough (typically greater than about 40°) so that the light undergoes total internal reflection at the glass-air interface and is reflected onto the solar cell. Grooves can be lengthwise along the conductor, or at an angle, angles. Rather than grooves, inclined faces can form pyramids, or other shapes. | |||||||||||
