Light intensity dependence of J-V characteristics of the PSC (a) and corresponding solar cell parameters: fill factor FF (b), short-circuit current density Jsc (c), and open-circuit voltage Voc (d). FF that monotonically increased up to the intensity of 10 mW cm−2 became saturated ...
Light intensity dependence of open-circuit voltage and short-circuit current of polymer/fullerene solar cells The open-circuit voltage (Voc) of polymer/fullerene bulk heterojunction solar cells is investigated as a function of light intensity for different temperat...

The greater the efficiency, the larger the output power intensity. In addition, a large output voltage is required to turn on an electrical appliance. This voltage can be taken as the voltage at the point of maximum power (Vmax) of an IPV cell, where Vmax≈ (0.72–0.78) VOC. [103] ...
The sample with n = 1 showed a distinct THz transmission peak, exhibiting no optical intensity dependence when illuminated at 700 nm (Fig. 10d), since that wavelength did not correspond to photogenerated excitons in the per- ovskite layer. When the samples were illuminated in the wavelength ...
For some time, urban traffic congestion has been increasing. Despite transit’s small market share, there has been the hope, if not the expectation, that transit can play an important role in reducing traffic congestion. Light rail has been invoked by a number of interests as a principal stra...
A|µ=0andArepresent the absorption spectra before and after MA coupling molecules, respectively. We define the sensitivity (ISEIRA) of MA as the intensity of the absorption difference spectrum whenω = ωm, that is,ISEIRA = ΔA|ω=ωm(Fig.S1). According to the above theory, ...

The choice of these conditions can be understood, in addition to the appealing roundness of the numbers, because most solar cells (c-Si especially) are more efficient at lower temperatures and higher intensity solar irradiance. Solar simulators are typically sold with a three-letter class system....
3 (b) (c). It can be seen that the absolute light intensity emitted by the UV tube has a significant attenuation with the increasing diameter (from 4 to 6 mm), and the lowest value is 50 μW/cm2/nm. The absolute intensity of the UV tube is also weaker with increasing length (...
