Abstract:
The present invention provides a colored thin film solar cell capable of minimizing reduction of efficiency of a thin film solar cell and improving a utility value by visually changing a black color of the thin film solar cell into an aesthetically pleasing color to exhibit an exterior appearance, thereby facilitating commercialization of the thin film solar cell, and provides a method for manufacturing the same.

Claim (Index 1):
A colored thin film solar cell comprising:\n a solar cell; and a band-stop filter provided on one surface of the solar cell, configured to reflect a portion of externally emitted light and transmit the remaining portion thereof to thereby visually change a color of the solar cell, wherein the band-stop filter is configured such that a first layer, a second layer, and a third layer are alternately stacked, and a repetition unit of the first-second-third layers is repeatedly stacked, wherein the refractive index of each of the first layer and the third layer is in a range of 1.2 to 1.6, and the refractive index of the second layer is in a range of 1.4 to 1.8, wherein each of the first layer and the third layer includes SiO 2 , and the second layer includes Al 2 O 3 , wherein the colored thin film solar cell satisfies conditions (a) and (b): (a) The band-stop filter has a reflective band half width in a range of 100 nm or less, and (b) A relational expression 1 is satisfied as follows, 0.80 \u2264 A B \u2264 1.00 , [ Relational \ue89e \ue89e Expression \ue89e \ue89e 1 ] wherein, A is light harvesting efficiency when one or more band-stop filters, each having a reflective band half width in a range of 100 nm or less, are employed, and B is light harvesting efficiency when the one or more band-stop filters are not employed.
