Chapter 12, Problem 12.103SP

Interpretation Introduction

(a)

Interpretation:

The color and approximate wavelength of maximum solar intensity at the Earth’s surface should be determined.

Concept introduction:

Solar irradiance spectrum above atmosphere and at surface.

Interpretation Introduction

(b)

Interpretation:

The semiconductor that absorb at a wavelength matched with maximum solar intensity should be determined.

Concept introduction:

The band gap energy can be represented as follows:

$E\text{ = }\frac{hc}{\lambda }$

Here,

E = band gap energy

h = Planck’s constant

c = speed of light

λ = wavelength
