Solar cell
A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer. Symbol of a Photovoltaic cell. A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1]
Photocell
A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance.
The composition of Standard Seawater and the definition of the ...
Chlorinity is not the only quantity that has been used as a ''standard'' measure of salinity; conductivity has also served this purpose. The two approaches are essentially equivalent for Standard Seawater (Millero et al., 1977), but the resulting values for derived quantities such as densities are not precisely consistent when composition anomalies are present, as for example …

Abstract. The chemical composition of individual particles can be revealed by single-particle mass spectrometers (SPMSs). With higher accuracy in the ratio of mass to charge (m/z), more detailed chemical information could be obtained. In SPMSs, the conventional standard-based calibration methods (internal/external) are constrained by the inhomogeneity of …
