Material properties of hydrogenated siliconn-layer and their impact on amorphous silicon (a-Si:H) solar cell are studied. By optimizing deposition parameters, mixed-phasen-layer with nanometer-sized Si crystallites embedded in a-Si:H matrix can be obtained, which demonstrates higher conductivity, lower activation energy and wider bandgap. Incorporating the mixed-phasen-layer into a-Si:H cell can significantly improve the open circuit voltage (Voc) up to 0.95 V, which is approximately 50 mV or 100 mV higher than those cells with a-Si:Hn-layer or microcrystalline siliconn-layer, respectively. The possible explanations ofVocenhancement brought by the mixed-phasen-layer have also been discussed. Up to now, we have achieved an initial efficiency of 9.4% with highVocof 0.945 V,FFof 0.70 andJscof 14.2 mA/cm2with a-Si:Hi-layer thickness of 300 nm and substrate temperature as high as 220 °C.
