Single-Crystal, Monocrystalline Sollar Cell


The development of photovoltaic technology up to today's 42.8% efficient cells starts with the Becquerel's discovery of photogalvanic effect in 1839 when he realized that the conductance of an electrolyte increased under illumination. Then in 1877 Adams and Day (UK) were to discover the photovoltaic effect on a junction between selenium and platinum which was the first observation of photovoltaic effect in solids. After several years of research and development in 1954, first 6% efficient Si solar cells were reported by Bell Labs, USA at the same time with 6% efficient Cu2S/CdS solar cells by Air Force, USA.


Solar Energy which is powerful and unlimited energy resource has taken place in these works. Although works on efficiency about continuous and uninterrupted use of solar energy is not successful enough, it has large potential which is already actively used with other renewable energy systems in many countries.

Designs are made with three different types of solar panels for lightening system which works network independent. After efficiency examinations are accomplished experimentally, recommendations are given about increase of efficiency.
