Amorphous Silicon Solar Cells

Amorphous Silicon–based Solar Cells

Crystalline semiconductors are very well known, including silicon (the basis of the integrated circuits used in modern electronics), Ge (the material of the first transistor), GaAs and the other III-V compounds (the basis for many light emitters), and CdS (often used as a light sensor). In crystals, the atoms are arranged in near-perfect, regular arrays or lattices. Of course, the lattice must ...

Light trapping in amorphous silicon solar cells

In order to simultaneously decrease the production costs of thin film silicon solar cells and obtain higher performances, the authors have studied the possibility to increase the light trapping effect within thin film silicon solar cells deposited on flexible plastic substrates. In this context, different nano-structure shapes useable for the back contacts of amorphous silicon solar cells on pl...

Amorphous Silicon Core-shell Nanowire Solar Cells

Nanostructures such as nanoparticles and nanowires have been demonstrated as powerful tools to improve light absorption[1-4], to enable low temperature process[5], to demonstrate multi-exciton generation[6], and to decouple the absorption depth and carrier diffusion length[7, 8]. Here we demonstrated the first amorphous silicon coreshell nanowire solar cells, which can be fabricated through a l...
