ABSTRACTWe show that high-efficiency and low-degradation hydrogenated amorphous silicon (a-Si:H) p-i-n solar cells can be obtained by depositing absorber layers in a triode-type plasma-enhanced chemical vapor deposition (PECVD) process. Although the deposition rate is relatively low (0.01-0.03 nm/s) compared to the conventional diode-type PECVD process (∼0.2 nm/s), the light-induced degradation in conversion efficiency of single-junction solar cell is substantially reduced (Δη/ηini∼10%) due to the suppression of light-induced metastable defects in the a-Si:H absorber layer. So far, we have attained an independently-confirmed stabilized efficiency of 10.11% for a 220-nm-thick a-Si:H solar cell which was light soaked under 1 sun illumination for 1000 hours at cell temperature of 50°C. We further demonstrate that stabilized efficiencies as high as 10% can be maintained even when the solar cell is thickened to >300 nm.

AbstractAttenuated total reflection Fourier transform infrared (ATR FTIR) spectroscopy and effective lifetime measurements have been used to characterize amorphous/crystalline silicon surface passivation in silicon heterojunction solar cells. The comparative studies show a strong link between microstructure factor R * and effective lifetime of amorphous silicon ( a -Si:H) passivation layers incorporating an interface buffer layer, which prevents the epitaxial growth. It is demonstrated that thin a -Si:H films deposited on glass can be used as ATR substrates in this case. The obtained results show that a -Si:H films with R * close to 0.1 are required for manufacturing of high-efficiency (>23%) silicon heterojunction solar cells.
