“…Therefore, the precise selection of solvent, additives, and precursors is very important to not only achieve complete dissolution of precursors and obtain a stable solution but also nucleation and growth of large crystals during precursor film formation. Widely used quaternary Cu‐chalcogenide precursors are metal oxides, metal salts, metal or metal chalcogenides, and metal organics . In addition, by using various amounts and types of chalcogens (S/Se) during the annealing process after the film formation, one is able to tune the band gap of the materials …”

Solution‐based thin‐film semiconductors offer a promising path for the mass production of low‐cost solar cells prepared at low temperatures. Thin‐film Cu‐based chalcogenides such as Cu(In,Ga)(S,Se)2 (CIGSSe) and Cu2ZnSn(S,Se)4 (CZTSSe) hold great promise and have been regarded as viable candidates because of the abundance of their constituent elements and environmentally nontoxic nature. This Review summarizes the recent progress in solution‐processed Cu chalcogenides (CuInSe2, Cu(In,Ga)(S,Se)2, Cu2ZnSnS4, Cu2ZnSn(S,Se)4) for thin‐film solar cells, with emphasis on the precursor solution deposited by spray pyrolysis and spin coating. The general aspects, current status, and recent research highlights are introduced and analyzed in detail. Finally, the challenges and future prospects of these solar cells are also discussed.

“…For comparison, the device fabricated by our RTE technique only had the maximum EQE of about 85%. This suggests the VTD-fabricated devices possess very low recombination losses of photo-generated carriers and long carrier lifetimes at CdS/Sb 2 Se 3 interface and in the whole Sb 2 Se 3 absorber 23 .

Antimony selenide is an emerging promising thin film photovoltaic material thanks to its binary composition, suitable bandgap, high absorption coefficient, inert grain boundaries and earth-abundant constituents. However, current devices produced from rapid thermal evaporation strategy suffer from low-quality film and unsatisfactory performance. Herein, we develop a vapor transport deposition technique to fabricate antimony selenide films, a technique that enables continuous and low-cost manufacturing of cadmium telluride solar cells. We improve the crystallinity of antimony selenide films and then successfully produce superstrate cadmium sulfide/antimony selenide solar cells with a certified power conversion efficiency of 7.6%, a net 2% improvement over previous 5.6% record of the same device configuration. We analyze the deep defects in antimony selenide solar cells, and find that the density of the dominant deep defects is reduced by one order of magnitude using vapor transport deposition process.

“…The VP devices show a J SC of 9.26 mA cm −2 , a V OC of 0.60 V, an FF of 65.2, and a PCE of 3.62%. All these parameters are higher than those of the SP cells, resulting in a higher PCE and indicating that the VP cells have lower charge recombination and longer carrier lifetimes . In addition, the VP devices show a smaller hysteresis (Figure S8, Supporting Information).…”

The main mechanism of most solar cells is that the light produces photogenerated electrons and holes, which are transferred to the electron transport layer and the hole transport layer (HTL), respectively. Then, these holes and electrons are transported to the anode and cathode, respectively, to generate electric current. Thus, charge transfer is a crucial process to fabricate efficient solar cells. Here, a fast vapor process is developed to fabricate SbSI and SbSI‐interlayered Sb2S3 solar cells by annealing an Sb2S3 film and SbI3 powder in an inert gas atmosphere. The charge transfer of the vapor‐processed SbSI solar cells is increased by shortening the path length from SbSI to the HTL. This is achieved by an intimate contact between SbSI and the HTL, which is obtained by optimizing the morphology of SbSI, resulting in a record power conversion efficiency (PCE) of 3.62% in pure SbSI‐based solar cells under standard illumination at 100 mW cm−2. In addition, the charge transfer of the SbSI‐interlayered Sb2S3 solar cells is enhanced by increasing the external driving force, an energetically favorable driving force provided by the TiO2/Sb2S3/SbSI/HTM structure, and the best‐performing SbSI‐interlayered Sb2S3 solar cell exhibits a PCE of 6.08%.
