在常温常压下,采用无电极金属催化化学腐蚀法在P型单晶硅片(100)基底上制备定向排列的硅纳米线阵列。研究了不同浓度硝酸银对纳米线阵列形貌、反射光谱性能的影响和具有电池雏形的硅纳米线阵列的光伏性能。结果表明:硝酸银浓度在0.02mol/L时为最佳配比;与普通绒面电池相比,硅纳米线阵列太阳能电池的光电转换性能明显优于普通绒面电池。用光谱响应分析手段分析硅纳米线电池光伏性能的影响因素,并提出解决办法。
An oriented array of silicon nanowire arrays was fabricated on a P-type monocrystalline silicon wafer (100) substrate by using electrodeless metal catalytic chemical etching at ambient temperature and pressure. The effects of different concentrations of silver nitrate on the morphology and reflectance spectra of nanowire arrays and the photovoltaic properties of silicon nanowire arrays with cell prototypes were studied. The results showed that silver nitrate was the best ratio when the concentration of silver nitrate was 0.02mol / L. Compared with ordinary suede cells, the photoelectric conversion performance of the silicon nanowire array solar cells was obviously better than that of ordinary suede cells. The influential factors of photovoltaic performance of silicon nanowires batteries were analyzed by spectral response analysis and the solutions were proposed.
