Solar power
Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.

Solar power
Nickel cadmium battery
Energy; Solar power
A battery containing nickel and cadmium plates and an alkaline electrolyte.
Peak power point
Energy; Solar power
Operating point of the I-V (current-voltage) curve for a solar cell or photovoltaic module where the product of the current value times the voltage value is a maximum.
Peak sun hours
Energy; Solar power
The equivalent number of hours per day when solar irradiance averages 1,000 w/m2. For example, six peak sun hours means that the energy received during total daylight hours equals the energy that ...
Peak watt
Energy; Solar power
A unit used to rate the performance of solar cells, modules, or arrays; the maximum nominal output of a photovoltaic device, in watts (Wp) under standardised test conditions, usually 1,000 watts per ...
Phosphorous (P)
Energy; Solar power
A chemical element used as a dopant in making n-type semiconductor layers.
Photoelectric cell
Energy; Solar power
A device for measuring light intensity that works by converting light falling on, or reach it, to electricity, and then measuring the current; used in photometers.
Photoelectrochemical cell
Energy; Solar power
A type of photovoltaic device in which the electricity induced in the cell is used immediately within the cell to produce a chemical, such as hydrogen, which can then be withdrawn for use.
