N2 - The high lifetimes recently measured for n-type multicrystalline and CZ silicon make innovative solar cells possible. This paper presents back junction solar cells made on n-type silicon, including a variety of simple designs based on the use of aluminum to form the pn junction, either with uniform or localized p+ regions. The feasibility of n+np+ continuous junction cast multicrystalline Si cells is demonstrated with a 15% efficiency back junction device (Jsc=33.3mAcm-2,V oc=580mV, FF=0.776, 4cm2, 180μm thickness). Voltages up to 594mV have been measured on some mc-Si devices. Using n-type CZ silicon, a 15.8% efficiency has been obtained (Jsc=33mAcm-2, V oc=600mV, FF=0.8). Localized rear Al junction devices on n-type FZ silicon have reached Voc=645mV and Jsc=27mAcm -2(no AR coating), showing the way for improved performance.
