WebSep 12, 2024 · Given an average wavelength of 589.30 nm, the average energy of the photons is E = hc λ = (4.14 × 10 − 15eVs)(3.00 × 108m / s) 589.30 × 10 − 9m = 2.11eV. The energy difference ΔE is about 0.1% (1 part in 1000) of this average energy. However, a sensitive spectrometer can measure the difference.

Chlorella vulgaris SAG 211–11b (Göttingen, Germany) was cultured semi-continuously in 1-L bottles filled with 800 mL 3N-Bristol medium (Bischoff and Bold 1963) at 25 °C.The cultures were bubbled with filtered air under continuous illumination of 50 (low light, LL) and 350 μmol photons m −2 s −1 (high light, … WebAlthough the two cases can reach high current density and electric power, the energy of photons emitted by the emitter is relatively low, i.e., lower than the bandgap energy of the InAs cell. Hence, the majority of the photons are not able to be converted into electricity and represent a massive waste of heat, and that is why the efficiency ...
