This paper describes the design, fabrication, and results of testing a cell with interdigitated p + and n + fingers on the unilluminated side of the solar cell. This design significantly reduces the problems of series resistance, contact grid shadowing, and voltage saturation which limit the performance of conventionally designed solar cells at
In summary, we have demonstrated that perovskite solar cells will fundamentally harvest photons more efficiently at certain regimes of high solar concentration, where they should be able to exceed the Shockley–Queisser limit and reach extraordinarily high open-circuit voltages close to 1.4 V (i.e., losses limited to near 200 meV). Suppression
Solar concentrators are used in solar photovoltaic systems to lower the cost of producing electricity. In this situation, fewer solar cells can be used, lowering the overall cost of the system. The purpose of this article is to design, construct, install and test a stationary (non-tracking) concentrating system in Irbid, Jordan.
In a conventional solar cell design, very low series resistances are difficult to obtain due to the practical sheet resistance of the front-side emitter that must be maintained to keep good quantum efficiency. Therefore, conventional silicon solar cells are not suitable for high concentration ratio—for example, greater than about ×50.
Due to the increased intensity of solar radiation on the surface of PV cell, temperature of silicon cells (SCs) raised to a very high range. Authors used PCMs of paraffin wax type having temperature range from 56 °C to 58 °C at the rear end of panel to mitigate the high-temperature issue.
As a result of saturation of open-circuit voltage increase with increase in temperature and decrease of fill factor due to series resistance effect under high concentration, efficiency of concentrator solar cells decreases with increase in concentration ration under high concentration condition.
A few years later, the first three steps to attain the 30% efficiency target had been addressed and resolved: the PC solar cell with a thin substrate and long carrier lifetime, with a textured and passivated front surface, proved to be the best design for high-efficiency concentrator solar cell , .
One of the most important targets for this application is to obtain the highest efficiency to convert solar radiation to electric power. High-concentration photovoltaics are aimed at enhancing sunlight conversion efficiency and reducing the costs of electricity.
