Thin-film technologies reduce the amount of active material in a cell. The active layer may be placed on a rigid substrate made from glass, plastic, or metal or the cell may be made with a flexible substrate like cloth. Thin-film solar cells tend to be cheaper than crystalline silicon cells and have a smaller ecological impact (determined from life cycle analysis). Their thin and flexible nature also

Today 80–90% of the solar cell technology is dominated by silicon-based materials , and silicon technology is the mainstream and proven to be a robust technology in the PV modules.The reason behind this is that silicon is the leading material used in bulk (1st generation), thin film (2nd generation) and some of the nano-structured (3rd generation) solar
Scalable thin-film solar cells are vital to transition to a sustainable energy future. Perovskite solar cells (PSCs) promise a low-cost and low-energy-input renewable
CdTe is the leading commercial thin film photovoltaic technology with current record laboratory efficiency (22.1%). However, there is much potential for progress toward the Shockley‐Queisser limit (32%). The best CdTe devices have short‐circuit current close to the limit but open‐circuit voltage has much room for improvement. Back contact optimization is likely to play a key role
Additionally, to achieve higher conversion efficiency, solar cells incorporating a back-contact structure, notably the IBC solar cells, are under ongoing research and development . Presently, dopant-free silicon solar cells are principally categorised into these three structural types for improved understanding and review.
The research on thin film CdTe photovoltaic solar cells has been re-gaining momentum in recent years, due to commercial advances made with regard to CdTe technology. Here,
The main materials used in CdTe thin film solar cell modules include transparent conductive oxide glass (TCO), high-purity CdTe, conductive pastes, and back electrodes.

Quasi-interdigitated back-contact (QIBC) perovskite solar cells (PSCs) possess unique optical structures for greater light harvesting potential than planar sandwich PSCs. However, this potential has not been fully fulfilled due to the lack of effective back contact designs for QIBC-PSCs. Herein, the newly devised structure features an enhanced light confinement
Back contact material choice is also influenced by their applicability in more complex architectures such as bifacial and tandem solar cells, where high visible and/or near‐infrared transparency
Based on this quality criteria, CdTe is a good choice as a solar cell material. Lately, research activities have shifted progressively toward thin film solar cells exploiting compound semiconductors with direct band gaps and high absorption coefficients, which have an enormous potential to achieve high efficiency and stability in contrast to a-Si solar cells.
The recent boom in the demand for photovoltaic modules has created a silicon supply shortage, providing an opportunity for thin-film photovoltaic modules to enter the market in significant quantities. Thin-films have the potential to revolutionise the present cost structure of photovoltaics by eliminating the use of the expensive silicon wafers that alone account for
However, most of these work focused on the Sb 2 Se 3-based thin film solar cells with superstrate structure due to the good adhesion and ohmic contacts for Sb 2 Se 3 layer.

The effect of substrate temperatures was studied and optimized. An additional selenization process, forming a thin MoSe 2 layer on the Mo back contact, was introduced prior to the deposition of Sb 2 Se 3 layer, which was found to further improve the back contact of substrate Sb 2 Se 3 thin film solar cells.
Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).
This is the dominant technology currently used in most solar PV systems. Most thin-film solar cells are classified as second generation, made using thin layers of well-studied materials like amorphous silicon (a-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), or gallium arsenide (GaAs).
A previous record for thin film solar cell efficiency of 22.3% was achieved by Solar Frontier, the world's largest CIS (copper indium selenium) solar energy provider.
