This paper describes the technical concepts and current status of back-contact module technology. A back-contact module has the advantage of a higher conversion efficiency because of less shading of the front of the cell, fewer inactive areas in the module and lower series resistance in the interconnection.
A back-contact module has the advantage of a higher conversion efficiency because of less shading of the front of the cell, fewer inactive areas in the module and lower series resistance in the interconnection. Aesthetically, back-contact modules are more attractive than standard modules.
The most efficient modules available on the market use back-contact (BC) technology. Sunpower has recently displayed modules reaching 20.4% efficiency powered by their current generation of 22.9% efficient Maxeon IBC (interdigitated back-contact) or BC-BJ (back-contact back-junction) cells. What makes back-contact modules more efficient?
Back-contact perovskite solar cells Within a decade of their discovery, PSCs have reached remarkable milestones. Perovskites are characterized by a crystal structure denoted as ABX 3.
The two main technical concepts related to back-contact modules – interconnector technology and printed circuit backsheet technology – are discussed in this paper. An overview is given of the production status of current back-contact module manufacturers to also show the significant potential of this technology in economic terms.
