In this paper, a unique structure of graded band gap (GBG) electron transport layer (ETL)
based lead-free Perovskite solar cell (PSC) is proposed and numerically investigated. The …

Bandgap evolution with composition variation of ABX3 perovskites is explored, where A=
MA, FA, Cs, Rb; B= Pb, Sn, Ge; and X= I, Br, Cl. To identify alternative lead‐free and stable …

CsSn0. 5Ge0. 5I3 perovskite is reportedly highly stable in ambient open air, lead free, and
has excellent optoelectrical properties. An inverted p–i–n solar cell device based on this …

We explored a lead-free, stable and inorganic perovskite absorber RbSn0. 5Ge0. 5I3 for
photovoltaic application. The stability in RbSn0. 5Ge0. 5I3 is due to the passivation effect of …

An all-inorganic lead-free tandem PV cell consisting of two sub-cells CsSn 0.5 Ge 0.5 I 3
(perovskite) based top cell/CIGS-based bottom cell has been designed, simulated, and …

In order to reduce current leakage and improve electron transfer in solar cells, charge
transport layers (CTL), mainly hybrid electron transport layers (h‐ETL), are considered as a …

Perovskite solar cells present a promising alternative to conventional silicon or lead-based
solar cells, offering a synergistic blend of cost-effectiveness and potential for elevated power …

This study investigates the potential use of eco-friendly, all-inorganic cesium tin iodide
(CsSnI 3) perovskite (PVK) as an absorber layer. Despite having higher temperature stability …

This work deals with the simulation and optimization of a single perovskite solar cell based
on the lead-free, inorganic perovskite absorber CsGeI 3 with a bandgap energy of 1.6 eV …

Among the emerging photovoltaic technologies, solid‐state dye‐sensitised solar cells
