ABSTRACTSi nanowires (NWs) have been fabricated by Ag-assisted electroless etching technique using an HF/AgNO3 aqueous solution. Scanning electron microscopy (SEM) measurements have revealed that a highly dense array of Si NWs with length of ∼1.4 μm is formed over the surface of both n-type and p-type Si (100) substrates. Following the fabrication of Si NWs, electron-beam evaporated p-type AgGa0.5In0.5Se2 thin film was deposited on the n-type Si NWs to form p-n heterojunction solar cells. The fabricated solar cells yield a 5.50% power conversion efficiency under AM (1.5) illumination.

ABSTRACTIn this paper the effect of Si1-xGex absorber layer thickness on thin film a-Si:H/crystalline-Si1-xGex/c-Si heterojunction solar cells (HIT cells) is studied by simulation and experiment. Cells with 1, 2 and 4 μm-thick epitaxial cap layers of p-type Si0.59Ge0.41 on top of 5 μm Si1-xGex graded buffer layers are fabricated and compared to study the effect of the absorber layer thickness. The results show no change in Voc (0.41V) and that Jsc increases from 17.2 to 18.1 mA/cm2 when the Si0.59Ge0.41 absorber layer thickness is increased from 1 to 4 μm. The effect of thickness on Jsc is also observed for 2 and 4 μm-thick Si and Si0.75Ge0.25 absorber layers. Experiments and simulations show that larger Ge fractions result in a higher magnitude and smaller thickness dependence of Jsc, due to the larger absorption coefficient that increases optical carrier generation in the near surface region for larger Ge contents.

The paper presents the results of research on the most advanced technology for manufacturing semiconductor photovoltaic energy converters. Methods of manufacturing and research of thin-film heterojunction solar cells based on p-type silicon are analyzed. The materials of the initial components and the structure of the thin-film solar cell were selected. According to the results of the developed technology for obtaining a high-efficiency Converter with a base layer of p-type by sputtering on a vacuum magnetron machine with accelerated heat treatment, ways to improve the performance of solar cells are indicated. The main requirements for the production of the most efficient photovoltaic converters are explained. The electrophysical properties of semiconductors were used as the basis for the material selection criteria
