Photonic Crystal-Integrated Semitransparent Solar Cell for Solar Greenhouse Application

Figure 3

Reflectance spectra of (a) type 1, (b) type 2, (c) type 3, and (d) type 4 photonic crystals. Dashed blue, green, and red lines represent wavelengths of 450, 550, and 660 nm, respectively. The low reflectance values at the wavelength regions of red and blue lights represent selective transmission of photosynthetically active radiation.
