Amorphous silicon (a-Si) is a promising material to serve as the top absorbing layers in tandem solar cells. However, due to its intrinsic high defect density, the thicknesses of a-Si layers are limited to a few hundred nanometers. This severely restricts the top cell current density, and therefore the total current density.

Renewable and Sustainable Energy Reviews, 2018
Abstract Progress made in perovskite solar cells (PSCs) in tandem with silicon, thin films, and organic solar cells has been reviewed. Tandem configurations are comprised of two or more cells and are designed to absorb the entire range of the solar light by the successive cells.

According to Shockley-Queisser theory, the efficiency of single junction Si solar cells is unequivocally limited to about 30%. This limit can be overcome by localized nanostructuring of the crystal lattice inside the silicon wafer. The nanocomponents of the device taking the form of electronic walls give the converter fascinating optoelectronic ...

Perovskites for tandem solar cells
Science, 2016Solar Cells Improving the performance of conventional single-crystalline silicon solar cells will help increase their adoption. The absorption of bluer light by an inexpensive overlying solar cell in a tandem arrangement would provide a step in the right direction by improving overall efficiency.

Solution‐Processed Organic Tandem Solar Cells
Advanced Functional Materials, 2006AbstractA solution‐processed polymer tandem cell fabricated by stacking two single cells in series is demonstrated. The two bulk‐heterojunction subcells have complementary absorption maxima at λmax ∼ 850 nm and λmax ∼ 550 nm, respectively. A composite middle electrode is applied that serves both as a charge‐recombination center and as a protecting ...

Abstract The performance of integrated tandem solar cell (ITSC) devices made from pn homojunctions has been investigated. The intrinsic electrical interconnection present in an ITSC device places important restrictions on the choice of the energy gaps of the semiconductors to be used. Total conversion efficiencies are calculated and they are compared

Complementary Materials for Tandem Organic Solar Cells [PDF]
, 2016 Traditionally, photocurrent generation in a typical organic photovoltaic (OPV) device has been thought to occur predominantly by photoexcitation of the electron donor and subsequent electron transfer to an acceptor material with a higher electron affinity than the donor (the Channel I mechanism).

A Hybrid Tandem Solar Cell Combining a Dye-Sensitized and a Polymer Solar Cell
Journal of Nanoscience and Nanotechnology, 2016A hybrid tandem solar cell was assambled by connecting a dye sensitized solar cell and a polymer solar cell in series. A N719 sensitized TiO2 was used as photocathode in dye-sensitized subcell, and a MEH-PPV/PCBM composite was used as active layer in the polymer subcell.
