what other layers it has?
Chromosphere, corona
Photosphere
the 2,000 kilometer-deep chromosphere (typically observed by filtered light, for example H-alpha) lies just between the photosphere and the much hotter but more tenuous corona.
what is the name of the suns surface layer Photosphere what is the range of temperature there? It is defined to have a temperature given by the effective temperature in the Stefan–Boltzmann law.

Photosphere [SEP] Other layers of the Sun
The Sun's visible atmosphere has other layers above the photosphere: the 2,000 kilometer-deep chromosphere (typically observed by filtered light, for example H-alpha) lies just between the photosphere and the much hotter but more tenuous corona. Other "surface features" on the photosphere are solar flares and sunspots.
