Improving Perovskite Solar Cell Stability Through Additives
This research project focuses on analyzing and reducing defects in perovskite solar cells. Perovskites (PVSKs) are crystalline materials that follow an ABX3 formula. Halide perovskites are promising solar energy sources due to low-cost manufacturing and compositional tunability, but long-term stability remains a challenge. To overcome this, gellan gum (GG,) a polysaccharide commonly used in the food industry, is added to more stable cesium formamidinium lead iodide (Cs0.2FA0.8PbI3) inks. The samples are blade-coated onto glass and analyzed through microscope images and photoluminescence (PL). Understanding defects in these cells guides future research on implementing PVSKs into functional power sources.
