Besides, because it can be manufactured by solution processing, it is very suitable for mass production in a low cost, roll-to-roll way. Thus, perovskite solar cell is believed to have potential to be commercialized in near future. In this research, we focus on two challenges that will meet when the device is in mass production. First, we cannot make the atmosphere of factory the same as in the glove box. Therefore, it is essential to develop an ambient process of cell fabrication. The second challenge is how to make a high efficiency solar module. For the first challenge, we build a dry air box with relative humidity controlled at 2~3%. The quality of film becomes better when the molar ratio of dimethyl sulfoxide to perovskite precursor is increased from 1:1 to 3:1. The short circuit current density of devices is increased from 14.3mA/cm2 to16.4 mA/cm2. Next, we substitute NiOx for PEDOT:PSS as hole transport layer and further raise the performance of devices from 11.3% to 12.9% and is the same as the performance of cells fabricated in glove box. For the second challenge, we use nanosecond pulse laser with a wavelength of 532nm to scribe P1, P2 and P3 line on the devices to make solar module. By changing the inject direction, pulse energy and pulse overlap ratio, we successfully scribe P1, P2 and P3 line using the single wavelength laser. And then, we fabricate perovskite solar module with 2 and 8 sub-cells on 4cm2 and 25cm2 substrate, respectively. The performance of each module is 12.82% and 11.76% calculated under active area. Both are the highest performance reported for perovskite module scribed with a single wavelength pulse laser based on our knowledge. Finally, we successfully use our perovskite solar module to drive beacon and senor which demonstrate the usage of perovskite solar cell.3183850 bytesapplication/pdf論文使用權限: 同意有償授權(權利金給回饋學校)鈣鈦礦太陽能電池雷射切割模組perovskitesolar celllaser scribemodulethesis10.6342/NTU201603637http://ntur.lib.ntu.edu.tw/bitstream/246246/273114/1/ntu-105-R03527031-1.pdf
