Unlocking the Potential of Perovskite Solar Cells: Enhancing Efficiency Through Acceptor Density Optimization

This abstract emphasizes the value of renewable energy sources and the promise of solar cells., in particular perovskite solar cells (PSCs), to effectively capture solar (PV) energy. It underlines the significance of switching from traditional fossil fuels to environmentally friendly and sustainable substitutes. PSCs are reaching their maximum efficiency, although they are less stable than conventional PV cells. The biggest obstacle to sustainability is the regular usage of hybrid organic-inorganic components in PSC. All-inorganic PSCs based on CsPbIBr2 have become more popular among them because to their good stability and acceptable band gap. The scientific community contributes attention to Cs-based PSCs to address this problem. The experiment entails adjusting the CsPbIBr2 layer's acceptor density and examining the effects on a number of metrics, including as
$\mathrm{J}_{\text{SC}}=15.46\text{mA}/\text{cm}^{2},\ \mathrm{V}_{\text{OC}}=1.46\mathrm{V}, \text{FF}=84.96\%$
, and
$\text{PCE}=16.77\%$
. The outcomes show that a
$1.66 \times 10^{16}\ \ \text{cm}^{-3}$
optimum acceptor density resulted in improved photovoltaic performance. The relevance of these results in improving PSC efficiency and encouraging solar energy's widespread adoption as a sustainable and ecologically benign power source is highlighted in the abstract's conclusion. The research supports continuing attempts to convert solar energy into a sustainable and effective source of energy.
