SOLAR CELL WITH INTERDIGITATED BACK CONTACT |
| 摘要 |
A solar cell with an interdigitated back contact is provided. The solar cell can include a crystalline silicon base layer and an electron collector region on a back side of the base layer. The electron collector region can include a first conductive oxide material electrically coupled to the base layer. The solar cell can also include a hole collector region on the back side of the base layer. The hole collector region can include a second conductive oxide material electrically coupled to the base layer. The electron collector region and hole collector region can form an interdigitated pattern. Furthermore, the first conductive oxide material and second conductive oxide material have different work functions. |
