Passivation characterisation of poly-Si based passivating contacts: Investigating the benefits of pinhole-enhanced passivation and a new method to extract metal-induced recombination

To meet the rapidly increasing global demand for energy, the potential of solar energy is being exploited towards its maximum capacity. The invention of poly-Si based passivating contacts has created an opportunity for c-Si solar cells to reach conversion efficiencies above 25%, while keeping the processing sequence relatively simple. Based on...
