Abstract
Basically the thin flim solar cells are fabricated on the foreign substrates like glass and stainless steel. The efficiency of nano crystalline solar cells is high compared to others. In vertically aligned nano wire solar cells the sensitivity is very less. First solar cell was introduced by bell in 1954. These solar cells are fabricated on the crystal silicon. The efficiency obtained after the fabrication is 6 to 22% from last 55 years. Depending upon the growth of technology the efficiency in solar cells also increased to 30.7%. In solar cells we use different number of materials but here as per development in technology we use semiconductors. By using semiconducting materials in solar cells the efficiency has increased up to 50%. In 1990s to generate energy we use photovoltaic effects that enable the use of nano structured materials. The nano structure depends upon the solar cells which exhibits the area by increasing the photon capture cells. So the main intent of this nano technology is to increase the energy efficiency compared to the conventional solar cells.
