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.
A perfect solar cell would have no losses apart from the ones dictated by physics or thermodynamics. In a semiconductor, photons with energy lower than the bandgap are not absorbed.
However, the SHJ solar cell is presently considered as a key technology to increase the conversion efficiency of terrestrial photovoltaics and a market share of 20% is expected for this technology by 2030. 6 Reflecting this target, in very recent years, several companies have launched pilot production or even mass production of SHJ solar cells and …
CIS (Copper-Indium/Selenide) Copper-indium-selenide (CuInSe 2) is a p-type semiconductor that has drawn tremendous attraction in the field of photovoltaic applications due to its wide bandgap (1.04 eV) and significant absorption coefficient with high stability is considered an alternative to the cadmium/lead-free toxic elements.

The dominant loss mechanisms in conventional photovoltaic cells are the inability to absorb photons below the band gap and the thermalization of solar photons with energies above the band gap energy. Third-generation solar cell concepts have been proposed to address these two loss mechanisms in an attempt to improve solar cell performance.

Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy.
