PHOTOVOLTAIC DEVICE WITH BAND-STOP FILTER |
| 摘要 |
<p>Photovoltaic device with band-stop filter. The photovoltaic device includes an amorphous photovoltaic material and a band-stop filter structure having a stopband extending from a lower limiting angular frequency omegamin>=0 to an upper limiting angular frequency omegamax where omegamax>omegamin. The band-stop filter structure is arranged in the photovoltaic device relative to the photovoltaic material in order to attenuate electromagnetic radiations reaching the photovoltaic material with angular frequencies of omega* in the stopband, so that omegamin<omega*<omegamax. The angular frequencies omega* correspond to electronic excitations omega* from valence band tail (VBT) states of the amorphous photovoltaic material to conduction band tail (CBT) states of the amorphous photovoltaic material.</p> |
