Hsin Han Lai Dye Loading and Short-Circuit Current Density Increased by Adding Nitric Acid with Multi-Layer Structure Applied for Dye-Sensitized Solar Cells
Hsin Han Lai;Hsueh-Tao Chou;Shi-Ting Chen;Chun-Hsin Wang;Zheng-Yue Chen;Ho-Chun Hsu

A compact layer is used to reduce the contact resistance, the dye loading is increased by adding nitric acid(HNO3), and the scattering layer is applied to enhance the scattering effect. The DSSC with the multi-layer structure of Compact/P25+HNO3/Scattering based photoanode shows an optimum short-circuit current density and energy conversion efficiency.

Kuan-Min Huang Blade Coating Large-Area Organic Solar Cells With Active Area of 216 cm2
Kuan-Min Huang;Hsin-Fei Meng;Hsiao-Wen Zan

Large-area organic solar panel with total active area of 216 cm2, including 16 cells connected in series. The efficiency of 5.9 % is reached for opaque panel illuminated by halogen lamp of 120,000 lux and 7.2% after calibration. For semi-transparent panel, 4.1% efficiency (4.9% after calibration) is reached.

Likarn Wang Wet Chemical Method for Growing Aluminum Oxide: A Negative Charge Film or a Back Surface Field for Crystalline Silicon Solar Cells ?
Likarn Wang;Yu-Ren Huang;Chen-Yu Wei;Chia-Po Lin

We present the results of growing aluminum oxide layers on rear sides of crystalline silicon solar cells with our wet chemical method. The chemical method can be used for mass production of aluminum oxide layers as an important passivation layer for today’s PERC solar cells.

Yu-Ting Hu Planar waveguide solar concentrator with symmetric air prisms as couplers
Yu-Ting Hu;Gui-Sheng Zeng;Sheng-Hui Chen

Symmetric air prisms were designed as the light couplers of a concentrator photovoltaics (CPV) system to increase the optical efficiency. The CPV system consists of a Fresnel lens with the planar waveguide coupler modeled and simulated by using ray tracing. Finally, a high efficiency and good uniformity concentrator was achieved.

Ching-Pao Sun Passivation of Interdigitated Back Contact Solar Cells by Graphene Oxide
Ching-Pao Sun;Yi-Chin Chen;Kuan-Yu Chen;Chu-Hsuan Lin

In this study, graphene oxide is used to passivate interdigitated back contact solar cells. The efficiency of solar cells can be effectively increased due to the lifetime enhancement contributed by graphene oxide on the surface.
