6 FAQs about [Heterojunction n-type single crystal cell]
How is n-n type heterojunction formed?
The n–n type heterojunction was formed by hydrothermal deposition of Sb 2 (S,Se) 3 and thermal evaporation of Sb 2 Se 3. We found that the n–n junction is able to enhance the carrier separation by the formation of an electric field, reduce the interfacial recombination and generate optimized band alignment.
Can n-n semiconductor heterojunction separate the exciton in a solar cell?
Carrier separation in a solar cell usually relies on the p–n junction. Here we show that an n–n type inorganic semiconductor heterojunction is also able to separate the exciton for efficient solar cell applications. The n–n type heterojunction was formed by hydrothermal deposition of Sb 2 (S,Se) 3 and thermal evaporation of Sb 2 Se 3.
Can n-type nanocrystalline silicon improve current and transport properties in heterojunction solar cells?
N-type nanocrystalline silicon (nc-Si:H (n)) layers are good candidates to improve current and transport properties in heterojunction solar cells. In this work, we perform thickness series alongside PH 3 doping series to unravel the desirable characteristics of nc-Si:H (n) along its growth direction.
What is the maximum voltage of a single crystalline p n heterojunction?
The dependence of short circuit current (Isc) and open circuit voltage (Voc) on gate voltage (b) and light intensity (d). The maximum value of Voc is 1.04 ± 0.2 V at VG = −40 V, which is the highest value achieved in organic single-crystalline p–n heterojunctions so far, to the best of our knowledge.
Can crystalline p n heterojunctions be used to study exciton physics?
Hence, achieving highly ordered crystalline p–n heterojunctions with atomically well-defined interface at monolayer thickness limit, is a powerful strategy for studying exciton physics without the limitations imposed by exciton diffusion lengths, as well as an efficient way to reveal the fundamental mechanisms in organic optoelectronic devices.
Does n n heterojunction increase the internal electrical field?
The Vbi of the SbSSe control device and SbSSe-SbSe device are 0.527 V and 0.676 V, respectively. This result is in good agreement with the VOC changes, indicating that the n–n heterojunction between Sb 2 (S,Se) 3 and Sb 2 Se 3 increases the internal electrical field.
