Thin-film cells convert solar energy into electricity through the photovoltaic effect. The micron-thick layers that contain photon-absorbing materials form thin-film solar cells that rest on a durable, resilient substrate. The endurance of thin-film solar panels sets them apart from the other competitors. Thin-Film Solar Panel Applications
With intense R&D efforts in materials science, several new thin-film PV technologies have emerged that have high potential, including perovksite solar cells, Copper zinc tin sulfide (Cu 2 ZnSnS 4, CZTS) solar cells, and quantum dot (QD) solar cells. 6.1. Perovskite materials
Most of the PV industry is dominated by Si-solar cells but its growth is hurdled by high costs and more amount of material required for its production. Newer technologies in photovoltaics using direct bandgap semiconductor has allowed for thinner solar cells. These techniques are known as thin film photovoltaics.
It is safe to assume that thin-film solar cells will play an increasing role in the future PV market. On the other hand, any newcomer to the production scene will, for obvious reasons, have a very hard time in displacing well-established materials and technologies, such as crystalline and amorphous silicon.
In this survey, the thin film solar cells are broken down into two categories: classic and innovative technology. A contrast is shown between the many kinds of thin-film solar cells that have been created to improve efficiency. We will explore the major aspects of the different models.
Despite initial challenges with efficient light conversion, especially among third-generation PV materials, as of 2023 some thin-film solar cells have reached efficiencies of up to 29.1% for single-junction thin-film GaAs cells, exceeding the maximum of 26.1% efficiency for standard single-junction first-generation solar cells.

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 (nm) to a few microns (μm) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick.
