NIST detector calibration uncertainty curve
Uncertainty in wavelength range is much higher than VIS range due to the UV light intensity is much smaller than VIS range.

近年來全聚合物太陽能電池，不管是在供體、受體材料組合研發還是製備技術都大幅成長，2019年3月，蘇州大學李永舫院士引領的團隊，張茂杰教授製備出單結全聚合物太陽能電池 (all-polymer solar cells, all-PSCs)，效率已突破11.2%，PM6:PZ1共軛聚合物優異的研究成果，盼可讓大面積高性能的all-PSCs邁入生產化。
該研究成果”11.2% Efficiency all-polymer solar cells with high open-circuit voltage.”發表於Science. China Chemistry.
Evaluating standard uncertainty
Modelling the measurement
1.1 In most cases, a measured is not measured Y directly, but is determined from N other quantities through a functional relationship ƒ :
For economy of notation, in thisGuidethe same symbol is used for the physical quantity (the measured) and for the random variable (see 2.1) that represents the possible outcome of an observation of that quantity. When it is stated that Xi has a particular proba...
Type B evaluation of standard uncertainty
3.1 For an estimate xi of an input quantity xi that has not been obtained from repeated observations, the associated estimated variance u2(xi) or the standard uncertainty u(xi) is evaluated by scientific judgement based on all of the available information on the possible variability of xi. The pool of information may include previous measurement data; experience with or general knowledge of the behaviour and properties of relevant materials and instru...
Type A evaluation of standard
2.1 In most cases, the best available estimate of the expectation or expected value μq of a quantity q that varies randomly [a random variable (A.1)], and for which n independent observations qk have been obtained under the same conditions of measurement (see A.2), is the arithmetic mean or average /q (A.3) of the n observations:
Thus,for an input quantity Xi estimated from n independent repeated observations Xik the arithmetic mean ...
