What is maximum light wavelength to be absorbed for creating electron-hole pairs in one type of Copper indium gallium (di)selenide (CIGS) photovoltaic cell? Assume this cell has a band gap of 1.35 eV. What happens, if this CIGS solar cell is irradiated with light having a wavelength of 950 nm? Explain how the CIGS semiconductor interacts with this 950 nm light.
