(a)
Interpretation: To determine the colour and approximate wavelength of maximum solar intensity at the earth’s surface and between
Concept introduction:
A photovoltaic cell is a semiconductor diode which converts visible light into direct current. Some photovoltaic cell also converts infrared or ultraviolet radiation into DC current. Photovoltaic cells are an essential part of solar-electric energy systems, which are becoming progressively important as alternative sources of utility power.
Given:
To determine:
The colour and approximate wavelength of maximum solar intensity at the earth’s surface.
