employed CuAlO2 with 80% transparency as the hole transport layer in perovskite solar cells, leading to a 16.3% improvement in power conversion efficiency [83]. Byrne et al. synthesized a single photoluminescent emission band of CuAlO2 under room temperature [64]. Further studies have been ...
具体作法是:将仪器的光源拆下,用标准灯代替原光源来测试标准光源灯的各条特征谱线,各条特征谱线的测量值与理论值之差,就是波长准确度。例如,使用汞灯测试,则设置波段范围为245～560nm,光谱带宽为2nm,测量方式设兰置为能量测量;样品为空气(样品和参考均为空气),进行波长扫描。而后将汞灯的各特征波长的测量值与其...

support customized so we can print your brand logo on the conduit. The available diameter sizes are 16mm/20mm/25mm/32mm/40mm/50mm. Usually it is popular used outside room under harsh environment like -25 degree and +100 degree due to high UV resistance. Itapplies to standard AS...
The opposite case is presented by Bi2Te3 where more optic phonons are involved in scattering when the temperature increases and thus the decrease of κL is faster at room temperature.108 The above studies emphasise the several factors causing strong PPI and low κL. Those zone center acoustic ...
