What is the best method for tracking the sun position, is-it by solar position calculation along the day of the year or by other method?

In solar energy application, often we should know the sun position at each instant. With the sun position calculation, I think we can establish a database for this purpose. Then we can use-it for...

Can we predict barrier potential in a contact metal-semiconductor or semiconductor-semiconductor using a theoretical approach ?

From band structure obtained with an existing calculation method , can we reach the result relating to the contact barrier between two materials ?

Can one determine the potential barrier in semiconductor-semiconductor contact using a calculated band structure for each material?

The band structure is easy to determine using ab-initio calculation (e.g Wien2k code). How can we determine the potential barrier obtained by the given materials from the band structure of each...

From DOS (density of state) calculation, can we determine the type (n or p) of the studied semiconductor?

Density of state or band structure energy can be obtained using any theoretical approach, for example DFT. So, from these results, is it possible to determine the type (n or p) of a given...
