Quantifying optical losses of silicon solar cells with carrier selective hole contacts

Study of Mono- and Polycrystalline Silicon Solar Cells with Various Shapes for Photovoltaic Devices in 3D Format: Experiment and Simulation

“…A lot of complex research is being done to increase the efficiency of solar cells and reduce losses. There are three main losses in solar cells: thermal [6], electrical [7] and optical [8]. More than 30 % of the light incident on a silicon-based solar cell is reflected [9].…”

Bilayer MoOX/CrOX Passivating Contact Targeting Highly Stable Silicon Heterojunction Solar Cells

“…The industrially produced hydrogenated amorphous silicon/crystalline silicon ( a -Si:H/ c -Si) heterojunction solar cells with an intrinsic a -Si:H thin layer (HJT) have enabled V OC values greater than 740 mV and a record power-conversion efficiency ( PCE ) up to 25.11% on a 6-inch cell. , However, the a -Si:H layers are typically grown by capital intensive plasma-enhanced chemical vapor deposition (PECVD) system using flammable and explosive SiH 4 as a precursor . Besides, the heavily doped amorphous silicon layer with a high absorption coefficient leads to considerable parasitic absorption , and, in turn, a decreased short circuit current density ( J SC ).…”
