This project is to develop high efficiency perovskite(PVSK) solar cell(SC) which can provide continuous power supply to the robots. PVSK SCs as a new type of high efficiency SCs, have attracted many research interests in recent years. Research has shown PVSK SCs showed better performance than crystal Si wafer based SCs at indoor lighting conditions. The goal of the project is to develop the laser scribing technology that can enable manufacturing large area PVSK solar modules of 1 m^2 or higher while the lab cell is less than 1cm^2. The method is to divide the large area PVSK SCs into small areas with the width of 5mm and connect them in series so that the internal resistance loss can be minimized. Laser scribing performs better than traditional mechanical scribing such as higher accuracy, higher throughput, etc. A nanosecond pulsed laser with wavelength of 532nm was chosen to be the laser source because of high instant power density of nanosecond pulse (>10^8 W/m^2) and high absorption by PVSK SCs which can heat up the PVSK absorber layer to high temperature to be evaporated and removed. The laser source can be controlled by a galvanometer with high accuracy of <1um and not limited by mechanical motors. The goal of the project is to achieve efficiency of 10% higher in the substrate area of >100cm^2 and limit the dead zone area ratio below 10%.雷射雕刻技術;鈣鈦礦太陽能電池;大面積鈣鈦礦電池模組;Laser scribing technology; Perovskite solar cell; large area perovskite solar module
