The other major contributor to this large increase in efficiency is the usage of MgZnO (MZO) within the cell. In a cell using a CdSe x Te 1−x /CdTe structure, MZO can be used in place of CdS. CdS is source of inefficient absorption, while MZO has a tunable band gap that can be optimized for high transparency and good alignment with CdSe x Te ...
A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solid solution on glass or plastic backing, along with electrodes on the front and back to collect current.
CdS: 2.42 [6] direct: Used in photoresistors and solar cells; CdS/Cu 2 S was the first efficient solar cell. Used in solar cells with CdTe. Common as quantum dots. Crystals can act as solid-state lasers. Electroluminescent. When doped, can act as a phosphor. II-VI: 2: Cadmium telluride: CdTe: 1.49 [6] direct: Used in solar cells with CdS.
CdTe is used to make thin film solar cells, accounting for about 8% of all solar cells installed in 2011. [4] They are among the lowest-cost types of solar cell, [5] although a comparison of total installed cost depends on installation size and many other factors, and has changed rapidly from year to year.

Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
