Abstract
A solar cell is disclosed to include a single crystal silicon chip, an electrode system, a glass plate cover, a polymer film set between the single crystal silicon chip and the glass plate cover, and a spectrum converter containing an inorganic phosphor, which absorbs radiation in purple, blue and green light of the Sun's solar radiation and converts the absorption into a photoluminescent light in yellow, orange-yellow and infrared area in the electromagnetic spectrum. The architecture characteristic of the solar cell increases the efficiency by about 20%.
Claims18
A solar cell comprising a single crystal silicon chip, an electrode system, and a glass plate covering said single crystal silicon chip, wherein the solar cell further comprises a spectrum converter set between said single crystal silicon chip and said glass plate, said spectrum converter having contained therein an inorganic phosphor to enhance the efficiency of the solar cell, said inorganic phosphor absorbing radiation in purple, blue and green light of the Sun's solar radiation and converting the absorption into a photoluminescent light in yellow, orange-yellow and infrared area in the electromagnetic spectrum.
A spectrum converter for use in a solar cell, said spectrum converter having contained therein an inorganic phosphor to enhance the efficiency of the solar cell, said inorganic phosphor absorbing radiation in purple, blue and green light of the Sun's solar radiation and converting the absorption into a photoluminescent light in yellow, orange-yellow and infrared area in the electromagnetic spectrum.
