\n\tAccording to a press release issued by Aalto University, it is the first time that black silicon cells do not limit energy conversion efficiency finals.\n<\/p>\n

\n\t \n<\/p>\n

\n\t"The efficiency of energy conversion is not the only parameter that should we consider," explains Professor Hele Savin, who led the study.\n<\/p>\n

\n\t \n<\/p>\n

\n\tThanks to the black cells to capture sunlight from low angles, they generate more electricity during the day, compared to traditional cells.\n<\/p>\n

\n\t \n<\/p>\n

\n\t"We proved that during the winter in Helsinki, the black cells have generated more electricity than traditional cells."\n<\/p>\n

\n\tCrystalline silicon solar cells dominate at present PV market. According to Popular Science, in 2011, 90% of all commercially available solar cells ARE made from crystalline silicon.\n<\/p>\n

\n\t \n<\/p>\n

\n\tUnder ideal conditions, they can transform sunlight into electricity at a rate of 25%. Basically, other types of solar cells efficiency is measured in terms of efficiency crystalline silicon cells.\n<\/p>\n

\n\t \n<\/p>\n

\n\tTheir major drawback is that they tend to be bulky.\n<\/p>\n

\n\t \n<\/p>\n

\n\tManufacturing solar cells being thin (thin-film) is cheaper than the production of crystalline silicon. Made from compounds of cadmium, the cells are 75 times thinner, and can absorb the sun better than silicon.\n<\/p>\n

\n\t \n<\/p>\n

\n\tThe only disadvantage of this type of cell is that it's not as good at converting sunlight into electricity, compared with crystalline silicon.\n<\/p>\n

\n\t \n<\/p>\n

\n\tLast year, in the laboratory, thin-film technology has reached a record efficiency of 20.4 percent.<\/strong>\n<\/p>\n

\n\tBlack silicon solar cells are similar to the cells of crystalline silicon, the difference is that the first is treated so as to be black on the surface.\n<\/p>\n

\n\t \n<\/p>\n

\n\tThe black color tends to absorb more sunlight, thus collect more energy, making them an attractive option for areas with little sun (such as the northern regions).\n<\/p>\n

\n\t \n<\/p>\n

\n\tIn spite of this, to date, black silicon cell technology has not advanced too much. For this reason, new research, showing an efficiency of 22.1%, it is very promising.\n<\/p>\n
