Strategies for doped nanocrystalline silicon integration in silicon heterojunction solar cells
Carrier collection in silicon heterojunction (SHJ) solar cells is usually achieved by doped amorphous silicon layers of a few nanometers, deposited at opposite sides of the crystalline silicon wafer. These...

Low-temperature high-mobility amorphous IZO for silicon heterojunction solar cells
Parasitic absorption in the transparent conductive oxide (TCO) front electrode is one of the limitations of silicon heterojunction (SHJ) solar cells efficiency. To avoid such absorption while retaining high conductivity, TC...

Silicon heterojunction solar cells: Excellent candidate for low light illuminations
We demonstrate that through careful optimization of contact layer parameters (thickness and doping) of silicon heterojunction cell structure, efficiency at low illumination is improved by almost 8 % while losing only about 4 % at 1 ...
