Efficient hybrid inorganic/organic tandem solar cells with tailored recombination contacts

10.5% efficient polymer and amorphous silicon hybrid tandem photovoltaic cell

“…Typically in thin-film tandem cells, ultrathin doped layers are employed to form tunnel junctions between the sub-cells with extremely high doping 2,13,14 . Although ultrathin heavily n-doped a-Si:H film can be obtained, hole collection layer (HCL) for polymer cells such as MoO 3 sulfonate (PEDOT:PSS) can be neither ultrathin nor highly doped [20][21][22] . Therefore, we applied ZnO:Al or indium tin oxide (ITO) as interfacial conducting layers (ICLs) between a-Si:H and polymer cells, to promote electrical conduction.…”

“…One hundred-nmthick TCO, ITO or ZnO:Al, was deposited on a-Si:H p-i-n. MoO 3 (15 nm) or PEDOT:PSS (40 nm) was deposited as an anode buffer for a subsequently deposited polymer back cell, serving as HCL for the back cell and as a charge recombination zone for electrons from the front cell and holes from back cell [20][21][22] . A 120-nm-thick PDTP-DFBT:fullerene blend film was deposited on the HCLs via spin coating (see ref.…”

Electrical and photovoltaic properties of Gaussian distributed inhomogeneous barrier based on tris(8-hydroxyquinoline) indium/p-si interface

“…El-Menyawy [16] has pointed out that the organic interlayer can produce substantial shift in the work function of the metal and in the electron affinity of the semiconductor, which in turn results in increment or decrement in barrier. Organic/ inorganic semiconductor heterojunctions showed photovoltaic behavior in which the electrical conversion efficiency is found to have reasonable values [17][18][19].…”

Progress in photovoltaic performance of organic/inorganic hybrid solar cell based on optimal resistive Si and solvent modified poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) junction

“…[13][14][15][16] Organic/ inorganic hybrid solar cell is also attracting considerable attention as one of promising third generation solar cells. [17][18][19][20][21][22] Organic solar cell is advantageous for low-cost device, but its performance is still low due to low charge mobility and short lifetime of organic materials. [23][24][25][26] Here, combining inorganic materials is a good solution for compensating weak points of organic materials and enhancing the performance.…”
