Solar thermal vs photovoltaic it is important to understand that solar thermal technology is not the same as solar panel, or photovoltaic, technology solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used to run a heat engine, which turns a generator to make electricity. For example, photovoltaic systems directly convert the solar energy into electrical energy while concentrated solar power systems first convert the solar energy into thermal energy and then further convert it into electrical energy through a thermal. 12 levelised cost of electricity generation 2 solar photovoltaic technologies 4 21 first-generation pv technologies: crystalline silicon cells 22 second-generation pv technologies: thin-film solar cells cost analysis of solar photovoltaics i in 2011 4. Photovoltaics and solar energy derek nalley and scott pinegar national science standards: students will use a photovoltaic (pv) cell to measure the energy from the sun the pre-test will evaluate the students' knowledge of pv cells and solar energy at the beginning of the module.

Analysis of solar photovoltaic development and constraints history in 1954, bell laboratories have developed the first solar cell and the energy efficiency was 6% back then (goetzberger et al 2002) the figure has been raised to over 10% within 18 months (green 2009.
