Reduced Graphene Oxide Counter Electrodes for Dye-Sensitized Solar Cells Processed By Atmospheric Pressure Plasma Jets
Hsiao-Wei Liu,Ting-Jui Wu,Sheng-ping Liang,Haoming Chang,Peng-Kai Kao,Jian-Zhang Chen,Cheng-Che Hsu,Pi-Tai Chou,I-Chun Cheng,
In this study, reduced graphene oxide counter electrodes for dye-sensitized solar cells processed by atmosphere pressure plasma jets are presented. The best achieved power conversion is ~5.19%, which is comparable to that of the reference cell using a reduced graphene oxide counter electrode processed with a conventional furnace. This new methodology greatly reduces the processing time from 15 min to 11 s and consumes only about 1/3 of the thermal budget per unit area in comparison with the conventional furnace calcination process.

Selective Emitter Formatiom Method for Crystalline Silicon Solar Cell : A Feasibility Study
Likarn Wang,Yen-Po Chen,Wei-Lin Yang,
Shallow trenches corresponding to metal contact area are first formed by screen-printing and chemical etching, followed by heavy doping over the whole front surface of the silicon wafer. The heavy doping remains at the shallow trench area while other areas become lightly doped through an etch-back method.

Optical Analysis of Conductive PEDOT:PSS films
Sheng Hsiung Chang,Hsin-Meng Cheng,Shih-Chin Lin,Chien-Hung Chiang,Chun-Lin Tien,
We present the structure, optical and mechanical properties of PEDOT:PSS films. The local conductivity of the PEDOT can be obtained by fitting the transmittance spectrum with transfer matrix method. The PEDOT:PSS film was used as an anode for P3HT:PCBM based photovoltaics, resulting in a power conversion efficiency of 3.28 %.

Impact of Light Management on Photovoltaic Characteristics of Single-Junction InGaP Solar Cells with Selective Filter
Yi-Chin Wang,Mu-min Hung,Yu-Chih Su,Peichen Yu,
We design a selective filter to confines the re-emitted photons from radiative recombination, and use Shockley-Queisser detailed balance model to calculate Voc. According to the results of simulation, we design the varied cutoff wavelength of selective filter on our devices. The Voc of InGaP solar cells has 1.5 mV enhancement with 650 nm cutoff wavelength filter.

Synthesis and characterization of perovskite for dye-sensitized solar cell
Chieh-En Chien,Chih-Ming Wang,Chih-Hung Tsai,
A broad organic-inorganic series of metal iodide perovskites with the general formulation ABI3, where A is the CH3NH3 and B is Sn, Pb and Sn/Pb composite are reported. The compounds have been prepared through a variety of synthetic approaches, and the nature of the resulting materials is discussed in terms of their and optical properties.

Improvement of CIGS solar cell conversion efficiency by using high performance Ti-doped GaZnO transparent conductive films
Yu-Lin Chang,Wei-Sheng Liu,
In this paper, the indium-tin-oxide (ITO) and Ti-doped GaZnO (GTZO) quaternary alloys were used as the transparent conductive oxides (TCOs) for Cu(In,Ga)Se2 (CIGS) solar cell application. The results indicated that GTZO thin films showed a high transmittance of 85.6%, and a low thin-film resistivity of 5.47×10-4 Ω-cm. The CIGS solar cells with high-performance GTZO TCOs exhibited an improved conversion efficiency of 8.2 %, which was higher than that with ITO TCOs (7.4 %). The improved device performances in this study demonstrated a high potential for developing high-performance CIGS solar cells by using GTZO TCOs.
