As the efficiency of silicon solar cells increases continuously, recombination at the metal contacts becomes more and more limiting, unless the contacts are passivated. Passivating contact layers on the front side, however, usually lead to parasitic

Plated Ni/Cu/Ag contacts are an industrially feasible metallization approach for high efficiency c-Si solar cells with low surface doping concentrations (10 18 cm -3 N D 20 cm -3 ). The 2d-simulations of this work define the minimum requirements on t

Continuous wave laser processes used to create solar cells with selective emitter and plated Ni–Cu front contacts are a widely discussed topic. Particularly low adhesion of the front metal contact has been identified as a serious challenge. In this

The adhesion of Ni–Cu-plated contacts requires annealing, which can lead to an electrical degradation of the solar cell. A combination of optical imaging methods and electron microscopical cross-section analysis was used to investigate the annealin

An evolutionary approach to increase the cell efficiency of the industrially widely used Al-BSF Si solar cell design is the implementation of a lightly doped emitter and plated Ni–Ag front side contacts. This work shows that this approach can give
