How efficient are solar panels (from the cheapest to the more efficient)Solar panels function on the principle of converting received energy, which reaches its surface into electricity. Most of the solar panels are converting less than 14% of the energy into electricity. Even if the number seems small, it is fairly a good percent of converted energy. There is also a possibility to obtain solar panels, which are more efficient than that with percents of around 40 or 50, but the price rises accordingly. Polymer solar cell - the new level of solar panelsSolar cells are greatly recognized for its environment friendly features and characteristics. New technology of creating plastic solar cell which is using photovoltaic technology to conjugate molecules and polymers had given rise to polymer solar cells in the market. Polymer solar cells have attracted great attention due to their fine features of being environmentally friendly, highly efficient, relatively inexpensive, flexible, and lightweight. |
