“…Moreover, ion diffusion at the absorber/spiro-OMeTAD interface at elevated temperatures favors the reduction of hole conductivity of the HTL and the deterioration of the solar cell performance [ 25 ]. To address this concern, graphene derivatives, especially graphene oxides (GOs), have been used as both passivation surfaces and charge transport layers in this type of solar cells [ [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] ]. These graphene-based materials are well suited for passivation and charge transport applications due to their unique electronic and optical properties, tunable band gap, and high conductivity [ 16 ].…”

“…CH 3 NH 3 SnI 3 , HC(NH 2 ) 2 SnI 3 , NH 2 NH 3 SnI 3 , and NH 2 (CH 2 ) 3 SnI 3 is the promising candidate to be a light sensitizer with suitable inorganic hole-transport material to achieve cost-effective and efficient lead-free perovskite solar cell [81,82]. Gagandeep et al uses the graphene as the layer for charge transport and is demonstrate the structure like n-Graphene/CH 3 NH 3 SnI 3 /p-Graphene which shows the efficiency of 10.67-13.28% [83]. Giorgi et al substituted Pb by TlBi (MATl 0.5 Bi 0.5 I 3 ) and InBi (MAIn 0.5 Bi 0.5 I 3 ) and depicted that these systems are quietly equivalent to MAPbI 3 and can be good replacements for PSCs [84].…”

Perovskites possess an interesting crystal structure and its structural properties allow us to achieve various applications. Beside its ferroelectric, piezoelectric, magnetic, multiferroic, etc., properties, these branches of materials are also useful to develop materials for various environmental applications. As the population is increasing nowadays, different type of environmental pollution is one of the growing worries for society. The effort of researchers and scientists focuses on developing new materials to get rid of these individual issues. With modern advances in synthesis methods, including the preparation of perovskite nanocomposites, there is a growing interest in perovskite-type materials for environmental application. Basically, this chapter concludes with a few of the major issues in the recent environment: green energy (solar cell), fuel cell, sensors (gas and for biomedical), and remediation of heavy metals from industrial wastewater.

“…Various literatures are reported for plane and textured (pyramidal and inverted pyramidal) solar cells [35,36]. E ciency is also dependent at various texturing angle and hence, desired texturing angle can be applied to produce maximum power conversion e ciency from solar cell [37]. Using AZO as n-type material, an e ciency of 6.8% is reported for Al:ZnO/CdS/CuInSe 2 polycrystalline solar cell in [10].…”

A maximum e ciency of 17% for ultra-thin n-type AZO layer and 17.5% for ultra-thin n-type TiO 2 layer based silicon heterojunction solar cell is reported by optimizing its properties which is much higher than practically obtained e ciency signifying a lot of improvements can be performed to improve e ciency of TiO 2 /Si and AZO/Si heterojunction solar cell. AZO layer and TiO 2 layer is used as n-type emitter layer and crystalline silicon wafer is used as p-type (p-cSi) layer for modelling AZO/Si and TiO 2 /Si heterojunctions solar cell respectively using AFORS HET automat simulation software. Various parameters like thickness of AZO, TiO 2 layer, p-cSi layer, doping concentration of donors (Nd) and effective conduction band density (Nc) are optimized. Finally, texturing at different angle is studied and maximum e ciency is reported at 70 µm thick p-type crystalline Silicon (p-cSi) wafer, that can be very helpful for manufacturing low cost HJ solar cells at industrial scale because of thin wafer and removal of additional processing setup required for deposition of amorphous silicon i-layer. Utilization of TiO 2 and Aluminium doped Zinc Oxide as n-type layer and p-cSi as p-type layer can help in producing low cost and e cient heterojunction (HJ) than compared to HJ with intrinsic thin layer HIT solar cells.
