An Alternative One-diode Model for Illuminated Solar Cells

2014 Energy Procedia  
A novel one-diode model is proposed for illuminated solar cells, which contains an additional variable resistance describing minority carrier diffusion from the bulk to the p-n junction. This model naturally describes the differences between photo-and electroluminescence imaging, as well as a well-known departure from the superposition principle. Index Terms-Electroluminescence (EL) imaging, one-diode model, photoluminescence (PL) imaging, solar cell modeling, superposition principle. 2156-3381
