Strategy to mitigate the dipole interfacial states in (i)a-Si:H/MoOxpassivating contacts solar cellsMazzarella, L. (author), Alcañiz Moya, A. (author), Kawa, Eliora (author), Procel Moya, P.A. (author), Zhao, Y. (author), Han, C. (author), Yang, G. (author), Zeman, M. (author), Isabella, O. (author)Electrical simulations show that the dipole formed at (i)a-Si:H/MoOx interface can explain electrical performance degradation. We experimentally manipulate this interface by a plasma treatment (PT) to mitigate the dipole strength without harming the optical response. The optimal PT + MoOx stack results in strongly improved electrical...conference paper 2020

Ziar, H. (author), Mishra, Sandeep (author), Isabella, O. (author), Zeman, M. (author)This paper suggests a measurable parameter, the so-called Shading Tolerability (ST), to be added on PV modules datasheet. Using this parameter, PV modules can be compared and classified regarding the ability to oppose shading effects. The parameter is extracted based on mathematical and probability analysis, then measured using a Large Area...conference paper 2018
