In this chapter, we will discuss the recent progress in the development of flexible a-Si TFT backplanes and displays with a focus on the approach using flexible plastic substrates and organic light-emitting diode (OLED) display media. Flexible OLED displays are believed to be the holy grail of the flexible display development efforts.
Because amorphous silicon is a noncrystalline and disordered silicon structure, the absorption rate of light is 40 times higher compared to the mono-Si solar cells [12].Therefore, amorphous silicon solar cells are more eminent as compared to CIS, CIGS, and CdTe solar cells because of higher efficiency. Such types of solar cells are categorized as thin-film Si solar cells, where

Most of recent studies focused on polycrystalline and amorphous silicon flexible thin-film solar cells [24], and monocrystalline silicon flexible solar cells have not had a breakthrough before 2008. In April, 2008, Rogers and co-workers [25] reported that they successfully made a scalable deformable and foldable integrated circuit by applying transfer printing technology to
The transition of thin-film transistor (TFT) backplanes from rigid plate glass to flexible substrates requires the development of a generic TFT backplane technology on a clear plastic substrate. To be sufficiently stable under bias stress, amorphous-silicon (a-Si:H) TFTs must be deposited at elevated temperatures, therefore the substrate must withstand high
AMORPHOUS SILICON–BASED SOLAR CELLS. In Dundee, Scotland, Walter Spear and Peter LeComber discovered around 1973 that amorphous silicon prepared using a "glow discharge" in silane (SiH. 4) gas had unusually good electronic properties; they were building on earlier work by Chittick, Sterling, and Alexander [3].

Amorphous Silicon Solar Cells By D. E. Carlson and C. R. Wronski With 33 Figures The first solar cell was made in 1954 by Chapin et al. [10.1] when they demonstrated that sunlight could be converted directly into electrical power with a conversion efficiency of ~6% using a p-n junction in single-crystal silicon. Solar cell research thrived in the early 1960s mainly as a result of the

For example, during the manufacturing process that utilizes glass as a substrate, once the transparent electrode is formed, a film of amorphous silicon is layered onto it. The metal film electrode is then formed and finally the solar cell is covered with a protective film. Since

Amorphous silicon solar cells were first introduced commercially by Sanyo in 1980 for use in solar-powered calculators, and shipments increased rapidly to 3.5 MWpby 1985 (representing about 19% of the total PV market that year). Shipments of a-Si PV modules reached ~40 MWp in 2001, but this represented only about 11% of the total PV market. This apparent

This chapter focuses on amorphous silicon solar cells. Significant progress has been made over the last two decades in improving the performance of amorphous silicon (a-Si) based solar cells and in ramping up the commercial production of a-Si photovoltaic (PV) modules, which is currently more than 4:0 peak megawatts (MWp) per year. The progress
The use of amorphous silicon in the silicon-based solar cells is the most recent and an emerging technology these days. It is a cost-efficient approach and offers the great flexibility. The only disadvantage of amorphous silicon-based solar cells is the reduced efficiency and poor performance.
The cells were made in a p‐i‐n structure by using doping gases in the discharge. The best power conversion efficiency to date is 2.4% in AM‐1 sunlight. The maximum efficiency of thin‐film amorphous silicon solar cells is estimated to be ∼14–15%. Content may be subject to copyright.
The main disadvantage of amorphous silicon solar cells is the degradation of the output power over a time (15% to 35%) to a minimum level, after that, they become stable with light . Therefore, to reduce light-induced degradation, multijunction a-Si solar cells are developed with improved conversion efficiency.
Amorphous silicon (a-Si:H) solar cells have to be kept extremely thin (thickness below 0.2 μm), so as to maximize the internal electric field Eint, and, thus, allow for satisfactory collection of the photo-generated electrons and holes. Therefore, light-trapping is absolutely essential for a-Si:H cells.
It is worth noting that these = conditions also apply to photoconductivity measurements that are made on isolated films of a particular material. The asymmetry in the drift of electrons and holes explains why amorphous sili-con–based pin solar cells are more efficient when illuminated through their p-layers.
Amorphous silicon solar cells can be fabricated in a stacked structure to form multijunction solar cells. This strategy is particularly successful for amorphous materials, both because there is no need for lattice matching, as is required for crystalline heterojunctions, and also because the band gap is readily adjusted by alloying.
