Flexible microelectronic devices have seen an increasing trend toward development of miniaturized,portable,and integrated devices as wearable electronics which have the requirement for being light weight,small in dimension,and suppleness.Traditional three-dimensional(3D)and two-dimensional(2D)electronics gadgets fail to effectively comply with these necessities owing to their stiffness and large weights.Investigations have come up with a new family of one-dimensional(1D)flexible and fiber-based electronic devices(FBEDs)comprising power storage,energy-scavenging,implantable sensing,and flexible displays gadgets.However,development and manufacturing are still a challenge owing to their small radius,flexibility,low weight,weave ability and integration in textile electronics.This paper will provide a detailed review on the importance of substrates in electronic devices,intrinsic property requirements,fabrication classification and applications in energy harvesting,energy storage and other flexible electronic devices.Fiber-and textile-based electronic devices for bulk/scalable fabrications,encapsulation,and testing are reviewed and presented future research ideas to enhance the commercialization of these fiber-based electronics devices.

We demonstrate the preparation of composite photovoltaic devices by using the blends of multi-armed CdS nanorods with conjugated polymer, poly[2-methoxy-5-（2＇-ethylhexyloxy）-1,4-phenylenevinylene] （MEH-PPV）. Multi-armed CdS nanorods are prepared by thermolysing single precursor cadmium ethylxanthate [Cd（exan）2] in pure hexadecylamine solution under ambient conditions. The photoluminescence of MEH-PPV can be effectively quenched in the composites at high CdS nanocrystal （nc-CdS）//MEH-PPV ratios. Post-treatment of the multi-armed CdS nanorods by refluxing in pyridine significantly increases the performance of the composite photovoltaic devices. Power conversion efficiency is obtained to be 0.17% under AM 1.5 illumination for this composite device.

The application of heavy-metal complexes in bulk-heterojunction（BHJ） solar cells is a promising new research field which has attracted increasing attention,due to their strong spin-orbit coupling for efficient singlet to triplet intersystem crossing.This review article focuses on recent advances of heavy metal complex containing organic and polymer materials as photovoltaic donors in BHJ solar cells.Platinum-acetylide containing oligomersor and polymers have been firstly illustrated due to the good solubility,square planar structure,as well as the fairly strong Pt-Pt interaction.Then the cyclometalated Pt or Ir complex containing conjugated oligomers and polymers are presented in which the triplet organometallic compounds are embedded into the organic/polymer backbone either through cyclometalated main ligand or the auxiliary ligand.Pure triplet small molecular cyclometalated Ir complex are also briefly introduced.Besides the chemical modification,physical doping of cyclometalated heavy metal complexes as additives into the photovoltaic active layers is finally demonstrated.

Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical

We think that the current classification of solar cells is not reasonable.We suggest that the first generations should be defined as element（silicon）solar cells,including monocrystalline,multicrystalline,microcrystalline,nanocrystalline,amorphous Si cells;the second generations should be defined as compound solar cells,including CdTe,CIGS,GaAs,CZTSSe cells,etc;the third generations should be hybrid（composite）solar cells,including dye-sensitized cells,perovskite cells,organic cells,quantum dot cells,etc.As two typical examples,perovskite solar cells and dye-sensitized solar cells are introduced.Dye-sensitized solar cell（DSSC）have become one of the typical representatives of the third generation solar cells owing to its low cost,easy preparation,high efficiency and environment benignity.Focusing on the PV technology golden triangle issues:efficiency,cost and stability,the scientists have devoted a great deal of endeavor since 1991.Ten important processes of DSSCs are introduced and emphasized.Lead halide amine perovskite solar cells（PSCs）have been dominant photovoltaic research topic in this decade owing to their low cost,easy preparation,and higher efficiency compared with other photovoltaic devices,as well as their unique features of perovskite.The PSCs have obtained a great progress with power conversion efficiency（PCE）of 3.8%in 2009 to more than 22%at present,and become the research hotspots of the third generation solar cells.Ten important processes of PSCs are introduced and emphasized.

Photoconductive properties of photodiodes based on composites of CuS nanoparticles and Poly[2-methoxy,5- （2＇-ethylhexyloxy）-p-phenylenevlnylene] （MEH-PPV） are investigated. By comparing composite devices with different MEH-PPV：CuS weight ratios of l：l （D2-1）, 1：1.25 （D2-2）, 1：2.5 （132-3） and 1：5 （D2-4）, it is found that the device D2 3 exhibited the best performance： the short-circuit current density of 17μA/cm^2 with the light intensity of 16.7mW/cm^2, the highest open-circuit voltage of 0,83 V, and the photosensitivity of 132 at reverse bias of - 1 V. The photosensitivity is improved by a factor of 5 compared with the undoped MEH-PPV device.

We report the effect of COOH-functionalized single walled carbon nanotubes（COOH-SWCNT） on the electrical and photovoltaic characteristics of Malachite Green（MG） dye based photovoltaic cells. Two different types of photovoltaic cells were prepared, one with MG dye and another by incorporating COOH-SWCNT with this dye. Cells were characterized through different electrical and photovoltaic measurements including photocurrent measurements with pulsed radiation. From the dark current–voltage（I–V） characteristic results, we observed a certain transition voltage（Vth/ for both the cells beyond which the conduction mechanism of the cells change sharply. For the MG dye, Vthis 3.9 V whereas for COOH-SWCNT mixed with this dye, Vthdrops to 2.7 V. The device performance improves due to the incorporation of COOH-SWCNT. The open circuit voltage and short circuit current density change from 4.2 to 97 m V and from 108 to 965 A/cm2 respectively. Observations from photocurrent measurements show that the rate of growth and decay of the photocurrent are quite faster in the presence of COOH-SWCNT. This observation indicates a faster charge separation processes due to the incorporation of COOHSWCNT in the MG dye cells. The high aspect ratio of COOH-SWCNT allows efficient conduction pathways for the generated charge carriers.

Compared to conjugated polymer poly[2-methoxy-5-（3＇ ,7＇-dimethyloctyloxy）-l,4-phenylenevinylene] （MDMO-PPV） solar cells, bulk heterojunction solar cells composed of zinc oxide （ZnO） nanocrystals and MDMO-PPV have a better energy conversion efficiency. However, ultraviolet （UV） light deteriorates the performance of solar cells composed of ZnO and MDMO-PPV. We propose a model to explain the effect of UV illumination on these ZnO：MDMO-PPV solar cells. According to this model, the degradation from UV illumination is due to a decrease of exciton dissociation efficiency. Our model is based on the experimentM results such as the measurements of current density versus voltage, photoluminescence, and photocurrent.
