Highly efficient industrial large-area black silicon solar cells achieved by surface nanostructured modification

Recent Progress of Black Silicon: From Fabrications to Applications

“…In particular, it can be distributed in remote areas, mountains, deserts, islands, and rural areas to save on costly transmission lines. In recent years, black silicon has become one of the materials used to make solar cells [ 72 , 97 , 98 , 99 , 100 , 101 ]. The research hotspot is to change the surface structure of black silicon [ 102 ] and passivate black silicon [ 103 ].…”

“…The filling factor of the black silicon solar cell was 78.63%, and the conversion efficiency was 17.3%. In 2016, P. Li et al [ 99 ] treated the black silicon surface with tetramethylammonium hydroxide for the 30 S, and obtained a black silicon solar cell with a better conversion efficiency, with a filling factor of 78.80% and a conversion efficiency of 19.03%. In 2018, G. Su et al [ 104 ] fabricated black silicon material using metal-assisted chemical etching of diamond wire saw polysilicon.…”

Analysis and optimization of alloyed Al-p+ region and rear contacts for highly efficient industrial n-type silicon solar cells

“…In order to determine the inuence of post-annealing on effective lifetime (s eff ), injection-dependent lifetime measurements were performed by the QSSPC technique. 23,24 The implied open-circuit voltage iV oc at one sun is used to determine the voltage of the device if contacts were applied, when only the recombination of the investigated emitter is considered. In Fig.…”

An Overview of Cleaning and Prevention Processes for Enhancing Efficiency of Solar Photovoltaic Panels

“…They found that Cu movement in the CIGS film amid thermal strengthening assumed an essential part in enhancing cell structure and the arrangement deformities in CIGS bulk. Li et al 60 studied the surface alteration procedure to minimize surface recombination and manufacture productive, modern, dark silicon sunbased cells. In order to reduce surface reflectance, Agnanoparticles assisted etching was applied to form font surface nanostructures on silicon wafers.…”
