Mu-Wen Lin Thermoelectric Module Integrated with Spectrum-Beam-Splitting Solar System to Exploit Infrared Energy
Mu-Wen Lin;An-Chi Wei;Jyh-Rou Sze

This study applies thermoelectric devices in a spectrum-beam-splitting solar system. In this system, the sunlight is divided to infrared and non-infrared light, and the thermoelectric devices collect infrared light through temperature difference to generate voltage.

Chien-Hung Kuo The Effect on Electrochemical Impedance Spectroscopy for Dye-Sensitized Solar Cell Under Low Illumination Intensity
Chien-Hung Kuo;Jung-Chuan Chou;Chih-Hsien Lai;Yi-Hung Liao;Cheng-Chu Ko

In this paper, we investigated the influences on electrochemical impedance spectroscopy for dye-sensitized solar cell under low illumination intensity. According to experiment results, the resistance of interface between electrolyte and TiO2 film(R2) increases with illumination intensity increasing.

Yijia J Chen Effect of Secondary Coating Treatment of TiO2 Anode on the Performance of Perovskite Solar Cells
Hong-Syuan Lin;Yijia J Chen

The novel secondary coating treatment of TiO2 anode of the perovskite solar cell significantly enhanced the photovoltaic efficiency of the solar cell by a factor of two. We revealed that the root cause of the enhancement should resort mostly to the conductivity improvement of the TiO2/perovskite interface.

Yu-Hsien Chiang All-inorganic selective contacts with microwave-synthesized oxide nanoparticles for highly stable perovskite solar cells
Yu-Hsien Chiang;Tzung-Fang Guo;Peter Chen

We report a novel and highly stable perovskite solar cell using inorganic electron transporting layer by solution-processed IZO nanoparticles. Combining with NiO as hole transporting layer, the all-inorganic selective contacts perovskite solar cells demonstrate power conversion efficiency over 16% and remain 85% of initial efficiency after 460 hours light soaking.

Ming-Hsien Li Robust nanoporous counter electrode for organic hole conductor free monolithic perovskite solar cells with substrate recyclability
Ming-Hsien Li;Yu-Syuan Yang;Kuo-Chin Wang;Yu-Hsien Chiang;Po-Shen Shen;Wei-Chih Lai;Tzung-Fang Guo;Peter Chen

A robust and recyclable monolithic substrate applying all-inorganic metal-oxide selective contact with nanoporous counter electrode is successfully demonstrated for efficient perovskite solar cells. The original device with 8.52% PCE can be rejuvenated by rinsing off perovskite material with DMF and refilling with newly deposited perovskite to deliver comparable performance.

Ming-Ju Wu Semitransparent Perovskite Solar Cells and their Tandem Structures Assembled with Si Cells
Ming-Ju Wu;Fang-Chung Chen

In this work, we mix Cs ion in perovskite for fabricating semitransparent perovskite solar cells. Then, the perovskite cell was stacked on a single crystal silicon solar cell by using UV-curable epoxy. The stacking four terminal tandem solar cell yield a summed efficiency of 13.64%.

Chi Feng Lin;Yun Da Chuang;Ci Wun Chen;Hsieh Cheng Han;Kuo Yuan Chiu;Tian You Cheng

We demonstrated sensitized solar cells with new type counter electrodes consist with cobalt and carbon. After modified the mixing ratio and annealing temperature, the optimums device showed the short-circuit current of 13.88 mA/cm2, open-circuit voltage of 0.78 V, fill factor of 68.1% and the highest power conversion efficiency of 7.4%.

Chih-Hung Tsai Reduced Graphene Oxide/Macrocyclic Cobalt Complex Nanocomposites as Counter Electrodes for Pt-free Dye- Sensitized Solar Cells
Chun-Jyun Shih;Wun-Shiuan Wang;Wen-Feng Chi;Wei-Chih Huang;Yu-Chung Hu;Yuan-Hsiang Yu;Chih-Hung Tsai

Macrocyclic Co complexes were successfully grafted onto graphene oxide to produce GO/Co nanocomposites with a large surface area, high electrical conductivity, and excellent catalytic properties. The results showed that the GO/Co (1:10) counter electrode exhibited an optimal power conversion efficiency of 7.48%, which was higher than that of the Pt.

Chi Feng Lin;Dong Lin Tang;Kuo Yuan Chiu;Hsin Shaw;Yuhlong Oliver Su;Hsieh Cheng Han

This study demonstrated the new-type materials served as absorption layer in dye-sensitized solar cells. It showed good performance on short-circuit current and open-circuit voltage of devices. The optimums device showed performance of 6.28% in power conversion efficiency, which was similar to the device efficiency of DSSC with conventional N719 dye.

Hung-Ting Lin Eco-friendly Carbon Quantum dots Films for Down-conversion in Organic Photovoltaics
Hung-Ting Lin

Carbon quantum dots (CDs) have been encapsulated within a polymer matrix to form a luminescent down-conversion layer. Our CDs can emitted green light by absorbing ultraviolet light which organic photovoltaics cannot utilize. We expect that by using the CDs films can enhance the response of organic photovoltaics in ultraviolet wavelength.
