Device which can generate electric power from sun radiation is known as solar cell or photovoltaic cell. Solar is particularly used for the power generation when the enrgy conversion source is sun light where photovoltaic use any light source. The production of energy like this called solar energy, also known as solar power.
Eergy conversion efficiency of the solar panel is the percentage of the power changed from absorbed sunlight into electrical energy, when solar panel is connected to an electrical circuit. Depending upon the time when it become important these can broadly be classified in three generations. Big sized, good quality and uni junction panels are included in first generation solar panels. These were expensive owing to large power and initial labor costs which was the major reason for cosltiness. Taking into account their efficiency these can be upto 33% efficient.
Technology advancements not only improved its quality in the second generation solar panels but also made it coast effective. Use of different production techniques like that of vapous deposition, electoplating and others helped to achieve it. Employing materials like cadmium telluride, copper indium gallium selenide, amorphous silicon and micromorphous silicon not only reduced material mass but also production expenses while not compromising on the quality and efficiency.
Third generation methodologies are focused at achieving the higher level of efficacy and elimination of the drarbacks in the second generation cells while not compromising on the manufacturing price. Presently, the goal is to get to the efficiency level of 30-60% whereas to contain productivity pricehike using the privailing methods. But enhancing efficacy also effects its inputs making the target much difficult to achieve. Still there are some mesns to get it with the usage of multi junction solar panels, concentrating the coming radiations and the usage of ultraviolet radiations, or the application of infrared radiations which can improve voltage generation particularly for night time working. Resarches are going on to make solar energy yet a better source of power.
