Thin film solar cells are favorable because of their minimum material usage and rising efficiencies. The three major thin film solar cell technologies include amorphous silicon (α-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe).
In 1981, Mickelsen and Chen demonstrated a 9.4% efficient thin-film CuInSe2/CdS solar cell. The efficiency improvement was due to the difference in the method of evaporating the two selenide layers. The films were deposited with fixed In and Se deposition rates, and the Cu rate was adjusted to achieve the desired composition and resistivity.
Typically, any thin film solar cells suffer from a huge reduction in light absorption within absorber layers (semiconductors), and that can cause efficiency drop due to inherent surface reflection. To achieve higher efficiency, some boosting techniques have been developed for better light absorption.
As an alternative to single crystal silicon photovoltaics, thin film solar cells have been extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to gain efficiency has been severely engaged over the years, the battle is not yet over.
