Abstract
(EN) A heterojunction battery, a preparation method therefor, and an application thereof. The heterojunction battery comprises a substrate (10), a first intrinsic amorphous silicon layer (20), an N-type doped amorphous silicon layer (30), a first transparent conductive oxide layer (60), a second intrinsic amorphous silicon layer (40), a P-type doped amorphous silicon layer (50), a second transparent conductive oxide layer (70), and a dielectric thin film (90). The heterojunction battery (100) further comprises a metal mesh (80), the metal mesh (80) penetrating through the dielectric thin film (90) and being fixedly connected to the first transparent conductive oxide layer (60) and the second transparent conductive oxide layer (70). The metal mesh (80) is composed of several first metal wires (8011) and several second metal wires (8012). The first metal wires (8011) are perpendicular to the second metal wires (8012).
