Amorphous Silicon–Based Solar Cells

Effects of hydrogen pressure on hydrogenated amorphous silicon thin films prepared by low‐temperature reactive pulsed laser deposition

“…4). hydrogen is incorporated in the amorphous matrix [8,28]. Additional reasons for bandgap widening in a-Si:H films include the formation of microvoids [4] and oxygen incorporation [13].…”

Multilayer nanoparticle arrays for broad spectrum absorption enhancement in thin film solar cells

“…The device performance is compared with a few existing reference designs to understand the improvement in absorption efficiency. A 300 nm thick active region of amorphous silicon with an Aluminium back contact and a 20 nm thick ITO front contact is considered for all designs [25][26][27][28]. Design 1, considered as the primary reference, contains only the a-Si layer and does not incorporate any nanoparticle arrays for light trapping.…”

Thin-Film Photovoltaics as a Mainstream of Solar Power Engineering

“…It was discovered that the electrical properties of a-Si deposited from a glow discharge in silane (SiH 4 ) are considerably different from single-crystalline silicon (Deng & Schiff, 2003). When put into silane of a small amount of phosphine ( Н 3 ) or boron (В 2 Н 6 ), electrical conduction of а-Si becomes n-type or p-type, respectively (Spear & Le Comber, 1975).…”

“…After annealing for several minutes at 130-150 , the solar cell properties can be restored. The positive effect of annealing can also occur (Deng & Schiff, 2003).…”
