Pei-Shen Wu,Yen-Ho Chu,Chien-Chieh Lee,Teng-Hsiang Chang,Yu-Lin Hsieh,Jenq-Yang Chang,Tomi T. Li,I-Chen Chen,
Application of optical emission spectroscopy (OES) to observe the stability of the chamber condition. We report the film properties of intrinsic a-Si:H passivation layers deposited with various film thickness that deposited by RF (13.56 MHz) PECVD and optimizing the passivation quality after anneal process.

Different Size of Graphite used in the Counter Electrode for Dye-sensitized Solar Cells
Sung Chung Tai,
To explore the application of the sub-micro particles of graphite(SMG) and micro particles of graphite(MG) at counter electrode(CE) in dye-sensitized solar cells(DSSCs).The results show that the efficiency of DSSCs with SMG counter electrode, 2.36% higher then that of MG CE, 2.07%,and it's attributed to the particle size of SMG is smaller than MG particle.

Fabrication of TiO2 compact precursor at Various Layer for Dye Sensitized Solar Cells
LI GUAN-YI,
The TiO2 compact layer was introduced to photoanode in dye-sensitized solar cells (DSSCs) to enhance the current density and photoelectric conversion efficiency. In this study, when the thickness of TiO2 compact layer was increased, the current density and photoelectric conversion efficiency are improved by 51% and 58%, respectively.

Evaluation of Collection Probability in GaAs Solar Cells from External Quantum Efficiency
Shih-Li Lin,Hung-Ruei Tseng,Shun-Chieh Hsu,Yin-Han Chen,Chien-Chung Lin,
The charge collection probability is one of the important quantity in a solar cell. We use two special functions to fit the quantum efficiency of a GaAs Solar cell and differentiate them and use the combination of these derivatives to approximate the charge collection probability.

InGaN-based solar cells with composition-graded junction
Zheg-Zhe Lin,Hsiao-Wei Huang,Kun-Yu Lai,
InGaN-based solar cells with three types of action regions are characterized: multiple quantum wells (MQW), single junction, and the junction with graded indium composition. Despite her largest fill factor, the device with graded junction exhibits lower conversion efficiency than that of MQW structure, which is attributed to insufficient carrier collection.

Double layer structure of DSSCs which using graphene to improve conversion efficiency
Cing-Jhih Huang,Lung-Chien Chen,Jia-Ren Wu,Jun-Kai Huang,Te-Yu Liu,
This study prepares a structure that can improve dye-sensitized solar cells (DSSCs) efficiency which used graphene and sandwich compound structure can enhance electronic transmission and electron conversion efficiency. When used this structure, the open circuit voltage(Voc) can increase from 0.54V to 0.6V and the fill factor (F.F) can increase from 0.565 to 0.585. Therefore, the efficiency can increase 62.6%.
