The compound Cu2ZnSnSe4 (CZTS) has attracted considerable attention as an alternative solar absorber to copper chalcopyrite (In,Ga) SE2 thin-film solar cells due to the suitable properties of CZTS solar energy. absorbent materials. CZTS is a direct P-type semiconductor with a reported optical band gap of 1.44 eV and a 1 to 1 absorption coefficient greater than 104 cm-1, corresponding to the prerequisites for sun-absorbing materials. Initial CZTS investigations showed that the compound has a tetragonal stannetite structure belonging to space group I4?2 m, with A = 5.6882?A, C = 11.3378?A and C/A = 1.993. However, recent density functional theory studies have shown that CZTS is also likely to crystallize kesterite belonging to space group I4? and suggested that the pyrite phase of CZTS could form in the synthesized samplesin partially disordered form.

Solar cells require circuitry to convert energy into electrical energy after light excitation. There are many types of solar cell materials. A. Silicon Series: 1. Monocrystalline Silicon: This material has a very high conversion efficiency (recently close to 30%), but the manufacturing cost is also very high. It is generally used in aerospace. 2. Polycrystalline silicon: The current common material is not as efficient as monocrystalline silicon (around 15-20%), but the manufacturing cost is much lower. 3. Amorphous silicon: low cost, low conversion efficiency (about 10% or less), generally used in electronic calculators, electronic watches, etc. B. Compound 1. InGaAs: A material developed by the Japanese company Sharp. The current maximum conversion efficiency has reached 35.8%. However, as it containsThe rare earth element In, its cost is generally used in aerospace. 2. Single crystal GaAs: The conversion efficiency also reached more than 20%. Due to its high cost, it is mainly used in aerospace. 3. CIS Series: Materials include Cu, In, Ga, Al, Se, S and other I-III-V compounds. The conversion efficiency is between 10% and 20%. Due to the wide selection of materials, the manufacturing method is relatively. easy, is now developing rapidly as a new type of material. There are also other emerging materials that are constantly emerging, such as CZTS (compounds of Cu, Zn, Sn, S), CdTe-CdS, etc. C. Organic Substances Nowadays, solar cells made of organic pigments, organic films, etc. are used. appeared. Although the conversion efficiency is still relatively low (less than 10%), organic substances being inexpensive and easy to manufacture, they cancan be used. Obtain advantages such as transparent solar cells and become new materials that have attracted much attention in recent years. That's about it, hope this helps.
