In the present contribution, a one-dimensional model for simulating the electric current distribution in solar cells accounting for a distributed series resistance is generalized to the presence of partially conductive cracks. The proposed model is used to perform a quantitative analysis of electroluminescence (EL) images of cracked monocrystalline silicon solar cells. A further generalization in a stochastic direction is also proposed in order to take into account randomly distributed defects typical of polycrystalline silicon. date: 2014 date_type: published publication: Energy Procedia volume: 55 publisher: Elsevier pagerange: 22-29 id_number: 10.1016/j.egypro.2014.08.005 refereed: TRUE issn: 1876-6102 official_url: http://dx.doi.org/10.1016/j.egypro.2014.08.005 funders: European Research Council funders: Italian Ministry of Education, University and Research projects: ERC StG CA2PVM (GA no. 306622) projects: FIRB RBFR107AKG citation: Berardone, Irene and Corrado, Mauro and Paggi, Marco A generalized electric model for mono and polycrystalline silicon in the presence of cracks and random defects.
