采用金属催化无电腐蚀（MCEE）和热化学气相沉积（CVD）工艺制备了硅纳米线太阳能电池。在这项研究中，我们研究了两种效果，紫外线/臭氧处理和使用微栅电极，以提高光吸收和减少太阳能电池设备中的光损耗。UV/臭氧处理成功地提高了转换效率。然后将微栅电极应用于经受背表面场（BSF）处理和快速热退火（RTA）的太阳能电池器件中。这些效应将转换效率从9.4%提高到10.9%。此外，为了减少表面复合和提高前电极的连续性，我们优化了MCEE工艺的蚀刻时间，给出了12.3%的高效率。
Silicon nanowire solar cells were fabricated by metal catalyzed electroless etching (MCEE) followed by thermal chemical vapor deposition (CVD). In this study, we investigated two effects, a UV/ozone treatment and the use of a micro-grid electrodes, to enhance light absorption and reduce the optic losses in the solar cell device. The UV/ozone treatment successfully improved the conversion efficiency. The micro-grid electrodes were then applied in solar cell devices subjected to a back surface field (BSF) treatment and rapid thermal annealing (RTA). These effects improved the conversion efficiency from 9.4% to 10.9%. Moreover, to reduce surface recombination and improve the continuity of front electrodes, we optimized the etching time of the MCEE process, giving a high efficiency of 12.3%.
