Reported timeline of research solar cell energy conversion efficiencies since 1976 (National Renewable Energy Laboratory). Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the
Recently, plasmonics has been used to trap the light at nanoscale to improve the absorption in solar cells. In this study, we construct a silicon thin-film solar cell (TFSC) using finite-difference time-domain (FDTD) simulation. The TFSC solar cell was designed with TiO2 anti-reflection layer, aluminum (Al) as a reflective layer, and silicon (Si) as a absorption layer.
The focus of this work is to determine the potential enhancement in efficiency that can be obtained from an ideal down-shifting thin film. The approach taken has involved an adaption of the Shockley–Queisser detailed balance limit [5], with further incorporations of the work presented by Trupke et al. and Badescu et al. [6], [7].

Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers to a few microns thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick.
Owing to their small size, thin-film solar panels are also very lightweight. They can weigh as little as 7 ounces per sq. ft., making them easily transported. 3. They Are Made of Safer Materials. Unlike most silicon-based panels, thin-film solar panel systems are made of Cadmium Telluride, Amorphous Silicon, and Gallium Arsenide.

So without further ado, let''s jump right into what are the different types of thin-film solar panels. A. Types of Thin-Film Solar Cells.

These experimental solar technologies continue to push thin-film cells closer to their theoretical maximum efficiency of around 30%.

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.

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.
This great development in the efficiency is not matched if the cost of the device is considered. The highly efficient PVs (mainly multi-junction solar cells) are prohibitively expensive , . On the other hand, the efficiency of the most dominant technology in the market (i.e. Si) is 25% in the lab and less than 20% commercially.
Thin film solar cell examples covered in this review are mainly of the following four categories: polycrystalline inorganic [Cu (In,Ga) (S,Se) 2 (or CIGSSe for short), and Cu 2 ZnSn (S,Se) 4 (or CZTSSe)], amorphous silicon (a-Si), organic photovoltaics (OPV) and organic-inorganic halide perovskite (perovskite) and etc.
