Abstract
We have developed efficient p-type crystalline-Si-based solar cells using a fast (1 min) and low-substrate temperature (<220°C) hot-wire CVD technique to deposit n-type Si thin films to form n-p junction. We achieved 13.3% energy conversion efficiency with Voc of 0.58 V, FF of 0.773, and Jsc of 29.86 mA/cm2 under AM 1.5 for a 1-cm 2 solar cell, which is the highest repotted efficiency to date for a single-junction device using the hot-wire CVD technique. Transmission electron microscopy reveals epitixal growth of Si at the junction, Quantum efficiency measurement on this solar cell shows over 90% response in the region between 540 and 780 nm, but a relatively weak blue and near infrared response. The solar cells show no degradation after 1000 hours of standard light soaking.
