| Abstract |
Today, there has been a growing interest in solar cells capable of absorbing the infrared(IR) region. IR-absorbing photovoltaics can improve the limitation of visible-absorbing photovoltaics with tandem structure. However, high performance IR solar cells can only be made of wafer type inorganic, which has high cost materials and fabrication method problem. In case of inorganics, the stability is main issue. The quantum dot is good alternaive for IR-absorbing photovoltaics, because it has controlable band gap and high optoelectronic properties with ligand passivation. The problem is that it is hard to apply the inorganic halogen ink ligand exchange directly because quantum dots show different surface properties as there size with different grown surface. Using our new exchange method, we have fabricated well-passivated large size quantum dot and solar cells. The filter lens was used to check the absorption over ~800 nm. |
