Abstract
The present invention discloses a solar cell which can enhance the absorption of the short-wavelength range radiation λ<400 nm of the sun and re-radiate in the wavelength range λ=500˜780 nm to enhance the solar cell's capability in absorbing more long-wavelength radiation and form separate electron-hole pairs so as to increase the output power of the solar cell assembly. Furthermore, the present invention also provides a transparent light conversion film for solar cells.
Claims25
A solar cell, comprising:
- a monocrystalline silicon wafer to hold the transparent light conversion film described later;
- and
- a transparent light conversion film which is shaped to be the form of a polymer layer with a transparent phosphor powder filled therein, is contacted with the outer surface of the monocrystalline silicon wafer, and can enhance the absorption of the ultraviolet in the short wavelength radiation λ<400 nm of the sun and re-radiate in the wavelength range λ=500˜780 nm.
A solar cell, comprising
- a monocrystalline silicon wafer to hold the transparent light conversion film described later;
- and
- a transparent light conversion film, made by melting phosphor powder and glass and disposed upon the monocrystalline silicon wafer, which can absorb a first specific wavelength range of the sun radiation and re-radiate in the second wavelength range.
A solar cell, comprising
- a monocrystalline silicon wafer;
- a glass disposed upon the monocrystalline silicon wafer;
- and
- a transparent thin layer disposed on the back of the glass, in which a transparent phosphor powder is filled therein and is contacted with the outer surface of the monocrystalline silicon wafer and which can enhance the absorption of the ultraviolet in the short wavelength radiation λ<400 nm of the sun and re-radiate in the wavelength range λ=500˜780 nm.
A transparent phosphor powder, which can enhance the absorption of the short-wavelength radiation λ<400 nm of the sun and re-radiate in the wavelength range of λ=500˜780 nm to enhance the absorption of long-wavelength radiation for the solar cell assembly and in turn form more separate p-n electron-hole pairs.
