High efficiency c-Si solar cells utilizing light-trapping phenomenon

Crystalline Silicon (c-Si) solar cell has presented itself as the ultimate solution for solving the cost and efficiency dilemma for the solar industry. We at Banpil have been working on the development of novel solar cells based on nanostructures to increase the conversion efficiency significantly over standard solar cells. These nanostructure based c-Si solar cells could potentially break the cost barrier that has thwarted the photovoltaic industry. In this work, we have designed ultrathin c-Si solar cells based on nanostructures, enabling a light trapping phenomenon to achieve a power density ranging from 0.91 W/g to 3.5 W/g, which is from 3.5 to more than 10 times over available standard c-Si solar cells.
