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.
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.
The reliability of thin film is questionable in comparison with the emergence and production of competitive and low-cost crystalline silicon solar panels.
However, this will reduce the efficiency as well. Using nanotechnology (Dubey et al., 2014), distributed bragg reflector (DBR) (Peters et al., 2012), and introducing grating structure (Trompoukis et al., 2012) can enhance the efficiency of the thin-film silicon solar cell.

Currently single crystal silicon (Si) solar cell exhibits a conversion efficiency of about 25% and has dominated the solar cell market. However, due to low light absorption and indirect bandgap features, single crystal Si layers of around 200–250 µm in thickness are usually needed to efficiently harvest the sunlight.
Thin-film solar cells (TFSCs) are the second-generation solar cells that have multiple thin-film layers of photovoltaic or PV materials. This is the reason why thin-film solar cells are also known as "Thin-film Photovoltaic Cell." These solar cells have a very thin layer of thickness (few nanometers) compared to conventional P-N junction ...
Thin-film solar cells are the second generation of solar cells. These cells are built by depositing one or more thin layers or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic, or metal. The thickness of the film varies from a few nanometers (nm) to tens of micrometers (µm). The film is much thinner than the first-generation conventional …
Thin-Film solar panels are less efficient and have lower power capacities than mono and polycrystalline solar cell types. The efficiency of the Thin-Film system varies depending on the type of PV material used in the cells but in general they tend to have efficiencies around 7% and up to 18% .

In terms of efficiency, thin-film solar cells generally have lower efficiency and power capacity compared to monocrystalline and polycrystalline types. Their efficiency ranges from about 7% to 22%, while monocrystalline cells average 15-25% and polycrystalline cells 13-16%. Despite this, thin-film panels are more efficient in low-light conditions, such as during …
