Customer ServiceSolar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
This great development in the efficiency is not matched if the cost of the device is considered. The highly efficient PVs (mainly multi-junction solar cells) are prohibitively expensive , . On the other hand, the efficiency of the most dominant technology in the market (i.e. Si) is 25% in the lab and less than 20% commercially.
Some thorough theoretical analyses with more restricted practical assumptions indicated that the limit is not far above the obtained efficiency . Currently, we are in the midst of the third generation solar cell stage.
Literature indicates that at a cell temperature of 36°C, efficiency somewhat increases by up to 12%. However, efficiency starts to decrease above this temperature, as Fig. 13 a illustrates. There are many efficient methods for controlling the operating temperature of solar cells which include both active and passive approaches.
Ross and Hsiao reported that the efficiency cannot exceed 29% based on an ideal theoretical analysis, where entropy and unavoidable irreversibility place a limit on the efficiency of photochemical solar energy conversion.
