Simply what is the Photoelectric effect on semiconductors?4 answersThe photoelectric effect on semiconductors refers to the phenomenon where the absorption of light generates an electric current in the material. This effect is observed in various types of semiconductors, including undoped semiconductors, multivalley semiconductors, and semiconductors with insulator-semiconductor stacks. In the case of undoped semiconductors, the effect is due to the intrinsic shift current that occurs when the material is exposed to an alternating electric field. In multivalley semiconductors, the diffusion of photoexcited electrons in different valleys leads to the generation of an electromotive force through the Dember photovoltaic effect. In semiconductors with insulator-semiconductor stacks, the capacitance of the stack is modified by the generation of carriers in the space-charge region, resulting in a change in the wetting contact angle of a droplet on the surface. These effects have potential applications in areas such as optofluidics and microfluidics.
What is the effect of the photoelectric effect on the conductivity of semiconductors?5 answersThe photoelectric effect has an effect on the conductivity of semiconductors. In unipolar multivalley semiconductors, the diffusion of photoexcited nonequilibrium heavy and light electrons is a correlated process, similar to ambipolar diffusion in the case of an electron-hole plasma. The light-induced intervalley transitions in multivalley semiconductors result in an imbalance between the subsystems of light and heavy electrons, leading to the electromotive force (emf) through the Dember photovoltaic effect. The emf in a "metal-semiconductor-metal" structure is determined by the conductivity of the heavy and light electron subsystems, as well as the surface conductivity of the metal-semiconductor interface. Additionally, the photoconductivity of semiconductors, such as germanium, silicon, and certain intermetallic compounds, can be controlled to study other processes and has practical applications in these materials.

UV lights have been found to have both positive and negative effects on the performance of solar cells. In some cases, UV radiation can lead to degradation and deterioration of solar cell performance. For example, in the case of Silicon heterojunction solar cells (HJT), exposure to UV radiation resulted in a decrease in carrier lifetime and efficiency. Similarly, UV irradiation was found to contribute to the degradation of dye-sensitized solar cells (DSCs), leading to a decrease in performance over time. On the other hand, UV light treatment has also been shown to improve the performance of certain types of solar cells. For instance, UV light treatment on the TiO2 layer of perovskite solar cells (PSCs) improved their power conversion efficiency. Additionally, UV illumination was found to improve the performance of organic solar cells incorporating solution-processed titanium suboxide (TiOx) as electron-collecting layers. Therefore, the effects of UV lights on solar cell performance can vary depending on the specific type of solar cell and the conditions of exposure.
How do photovoltaic cell readings vary with temperature?
5 answers
Photovoltaic cell readings vary with temperature. As the temperature increases, the open-circuit voltage decreases while the short-circuit current increases. This behavior can be explained by the band theory of solid-state physics, where the increasing temperature causes a narrowing of the forbidden gap and a shift of the Fermi energy level towards the center of the forbidden gap. These effects lead to a reduction of the potential barrier in the band diagram of the illuminated PN junction, resulting in a decrease in photovoltaic voltage. Additionally, the narrowing of the forbidden gap leads to a higher generation of electron-hole pairs in the illuminated PN junction, causing an increase in short-circuit current. The efficiency of PV energy conversion also decreases with increasing temperature.

How schottkey barrier height calculate coreectly?
5 answers
The Schottky barrier height can be calculated correctly using various methods. One method involves performing non-linear curve least square data fitting on a Fowler formula using experimental data obtained from an I-V experiment at a certain temperature. The fitting parameter obtained from this step is then substituted back into the Fowler formula to obtain the heat emission current at the temperature. Next, non-linear curve least square data fitting is performed on a Richard-Dushman formula using the heat emission current at each temperature. Finally, the Schottky barrier height is computed based on the fitting parameter obtained.Another method involves measuring the photovoltaic value of a pn junction photovoltaic photodiode under open-circuit conditions and increasing the illumination intensity of a background light source until the steady-state photovoltaic value of the photodiode is not increased any more. Ultrafast pulse lasers are then used to saturate the measured transient-state photovoltaic value of the photodiode, and the minimal value of the transient-state photovoltaic value is acquired. Calculation is then carried out using formulas to extract the electrode interface Schottky barrier height of the pn junction photovoltaic photodiode.A capacitance-voltage (C-V) method can also be used to extrapolate the Schottky barrier height on n-GaN with an exponential carrier concentration profile. The carrier concentration profile of the unintentionally doped GaN is determined by C-V measurement, and based on this profile, one-dimensional Poisson's equation is calculated to obtain the relation between bias voltage and depletion width. The Schottky barrier height is then obtained by fitting the curves of 1/C^2 and V with the experimental data, using the Schottky barrier height itself as a fitting parameter.
