Development of Printable Electronics on Flexible Substrate
Ta-Ya Chu,

In this presentation, I’ll give an introduction to the “NRC Printable Electronics Flagship Program” and review the technologies for organic photovoltaics and printed transistors. The achievements for the development of organic photovoltaics at NRC will be presented and discuss the challenges ahead for commercialization. The different printing techniques will be presented to address the difficulties of printing process instead of spin coating process in the lab. The development of inkjet-printed PMOS inverters and logic gates on flexible substrates will be presented. The manufacturing yield of 97% of inkjet-printed OTFTs has been demonstrated. Optimized enhancement-load PMOS inverters on PET substrate obtained a high voltage gain up to 11 v/v.

Yu-Cheng Kao Award Candidate Performance enhancement of III-V multi-junction solar cells by using indium-tin-oxide electrode
Yu-Cheng Kao,Jia-Hao Liang,Fan-Lei Wu,Ming-Chun Tseng,Ray-Hua Horng,

The performance improvement of InGaP/InGaAs dual-junction solar cells with an ITO transparent electrode was explored. It is found the ITO electrode can not only play the transparent electrode, but also be used as an anti-reflection layer resulting in increasing the absorption efficiency of the visible light.

Kuen-Feng Lin Award Candidate Plasmonic Enhancement of the Exciton Generation for the Tri-Iodide Perovskite Absorber
Kuen-Feng Lin,Sheng Hsiung Chang,Sheng-Hui Chen,

In this study, the absorption coefficient and refractive index of a tri-iodide perovskite absorber (TPA) was obtained by fitting the transmittance spectra of TPA/ PEDOT: PSS/ITO/glass using the transfer matrix method. The 3-D FDTD method was used to design a 2-D periodic Cu nanoplasmonic structure to enhance the exciton generation at the interface between TPA and Cu nanoparticles. Base on this method the thickness of the TPA film can be reduced with the same absorption property.

Shih-Chen Chen,Yi-Ju Chen,Wei-Ting Chen,Yu-Ting Yen,Tsung-Sheng Kao,Yu-Kuang Liao,Kaung-Hsiung Wu,MartinD. B. Charlton,Din-Ping Tsai,Yu-Lun Chueh,Hao-Chung Kuo,

In this work, we have successfully demonstrated the great advantage of plasmonic Au nanoparticles for efficiency enhancement of CIGS flexible photovoltaic devices. The enhancement of external quantum efficiency(EQE) and photocurrent have been systematically analyzed by simulation and experiments.

Hau-Vei Han Award Candidate Enhanced Current Density and Power Conversion Efficiency in Solar Cells by Using Luminescent Downshifting Phosphors
Hau-Vei Han,Chien-Chung Lin,Kuo-Ju Chen,Tien-Lin Shen,Jie-Ru Li,Hao-Chung Kuo,Peichen Yu,

The silicate phosphor on the surface of GaAs solar cell are demonstrated to have promising potential for efficient solar spectrum utilization. The solar cells showed an enhancement of 22.8% in short-circuit current density and approximately 25.3% in power conversion efficiency when coated with silicate phosphor particles.
