摘要: We describe a very simple experiment that allows college students in introductory physics courses to plot the I-V characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor and light conversion efficiency. ...
It is found that the 57-μm flexible and thin solar cell shows the highest power-to-weight ratio (1.9 W g−1) and open-circuit voltage (761 mV) compared to the thick ones. All of the solar cells characterized have an area of 274.4 cm2, and the cell components ensure ...

A more suitable parameter for comparison is the diode factor of the solar cell, which is the main parameter governing the FF, assuming that the solar cell does not suffer from too large series (> 0.4 Ω cm2) or too low shunt (< 1 kΩ cm2) resistances [60]. ...

The tandem organic solar cell with the interconnecting layer of e-TiO1.76/PEDOT:PSS exhibits a PCE as high as 20.27%. This result is certified as 20.0% by the National Institute of Metrology, China. Summary As a promising strategy for enhancing light utilization, constructing cell with tandem ...
The first chapter of the e-book starts off with a reference to galvanic cells. Users can reorganise and reflect on their respective prior knowledge. The set-up of the first experiment, the so-called photogalvanic 2-pot-cell, is analogous to a classical galvanic cell, so students can compare...
shows only a low decrease of efficiency with elevated temperature and low light intensity, maintaining almost optimum values for ambient conditions, under which most of the solar energy is incident on the solar cell. The overall energy yield differs from what is expected from standard test ...
Vibration experiment A 1,260 mm × 860 mm flexible SHJ module was installed on a large vibration platform, in which the module was supported by metal holders with a height of approximately 3 cm. The module vibrated in thezdirection, expressed asZ(t) = Z0sin(2πt/T), ...
