This review provides a comprehensive overview of back-contact (BC) solar cells, commencing with the historical context of the inception of the back-contact silicon (BC-Si) solar cells and its progression into various designs such as metallization wrap through, emitter wrap through, and interdigitated configurations.
As the global solar industry races toward higher efficiency and better performance, Back Contact (BC) solar modules are emerging as one of the most promising technologies for the next wave of innovation.
Back Contact (BC) solar modules are photovoltaic panels in which all the electrical contacts — both positive and negative — are located on the rear side of the solar cell. This contrasts with most conventional technologies, where metallic contacts are present on the front, partially shading the light-absorbing surface.
Back contact (BC) solar cells, realised through various contact formation technologies, are expected to represent the ultimate evolution of Si PV technology in terms of both efficiency and cost-effectiveness. In this study, the evolution of Si solar cell structures is reviewed. Challenges for BC solar cell manufacturing are discussed.
