PV Cells 101: A Primer on the Solar Photovoltaic Cell
How a Solar Cell Works. Solar cells contain a material that conducts electricity only when energy is provided—by sunlight, in this case. This material is called a semiconductor; the "semi" means its electrical conductivity is less than that of a metal but more than an insulator''s.
Solar Cell Technology Online Course provides an extensive program to help students understand photovoltaic systems and the physics of solar energy transformation. The world relies heavily on renewable sources to reduce global warming, hence it issolar technology that has become essential in resolving global energy supply challenges. ...

Micro-Fractures in Solar Modules: Causes, Detection and Prevention
Micro-fractures, also known as micro-cracks, represent a form of solar cell degradation. The silicon used in the solar cells is very thin, and expands and contracts as a result of thermal cycling. During the day, the solar panels expand because of higher temperatures. Small imperfections in the silicon cell can lead to larger micro-cracks.
