本文制备了一系列以PM6为给体、窄带隙材料Y6为受体的聚合物太阳能电池,分别以100 nm铝或1 nm金/(20,15,10 nm)银作为电极来制备不透明及半透明器件.以不透明器件为基础,优化有源层的厚度,当有源层厚度为100 nm时,器件的光电转换效率达到了15.83%.100 nm厚的混合薄膜的平均可见光透过率为50.5%,这表明利用该有源层有望制备出高效率半透明聚合物太阳能电池.分别以1 nm金/20 nm银,1 nm金/15 nm银,1 nm金/10nm银复合电极代替铝电极(这种金/银复合电极在可见光范围内透过率较高,在近红外光范围透过率较低),所制备的半透明聚合物太阳能电池的光电转换效率和平均可见光透过率分别达到了14.20%和8.9%,13.32%和12.5%,12.37%和18.6%,这处于目前报道的半透明聚合物太阳能电池性能最高的行列.这一工作表明:开发高可见光透过率、低近红外光透过率电极以及使用窄带隙材料为有源层是制备高效率半透明聚合物太阳能电池的有效方法.

Lens density measurements by two independent psychophysical techniques

Eye and Vision 2016年第1期3卷 188-196页

Background:Cataract,a leading cause of vision impairment,is due to the lens becoming excessively optically dense.Change in the lens optical density(LOD)could be a useful indicator of incipient nuclear cataract and would necessitate the development of accurate measurement techniques.Mapcat sf^(TM) is a heterochromatic flicker photometer for measuring macular pigment optical density(MPOD)under Photopic conditions.In the process,it also measures LOD that is needed in the calculation of MPOD.LOD is then converted by the instrument to“lens equivalent age”(LEA).However,varying cone photoreceptor ratios among individuals could affect the LEA measurement.Scotopic vision is mediated by rod photoreceptors;therefore,LEA measurement under scotopic conditions potentially provides a reliable standard for assessing other methods.The study was conducted to test the level of agreement between the LEA data obtained under Photopic and scotopic conditions for a sample population.We also comment on factors that might contribute to any disagreement.Methods:LEAs were obtained by Mapcat sf for 25 subjects and compared with those obtained under absolute scotopic threshold conditions.Results:The mean scotopic LEA for the subjects was 2.7 years higher than the mean Photopic LEA,but this difference was not statistically significant.Measurements by the two methods were reasonably correlated(r 2=0.59,p<0.0001).Significant individual differences in LEA by the two methods were found for six of the 25 subjects.Although our calculations included a standard long-to medium-wavelength-sensitive cone ratio,we found that different ratios could be found that rendered the differences in LEA insignificant for two of these six subjects.Variability in pupil diameter during scotopic measurements was considered another potential source of discrepancy between LEAs by the two methods.Conclusion:The absolute threshold technique,with long adaptation times,is probably impractical for routine lens density measurement,whereas Mapcat sf provided a rapid,straightforw

Literature Review about spectral sensitivity of the eye

引用

生物技术世界 2015年第3期12卷 192-192页

作者： Cheng Lirong Jingzhou Vocational College of Technology

The visible portion of spectrum covers the wavelength range from approximately 380nm to 780nm and the eye discriminates between different wavelengths in this range by the sensation of colour.
