Abstract
A lead-free solar cell module having a top protective layer, a middle photoactive layer, a bottom protective later and a frame with the top protective layer, middle photoactive layer and the bottom protective layer secured in the frame. The middle photoactive layer includes a back metal contact layer including gold (Au), a hole transport layer (HTL) including copper oxide (CuO), an inorganic absorber layer including rubidium germanium iodide (RbGeI), a perovskite absorber layer including methylammonium tin iodide (MASnI), an electron transport layer (ETL) including fullerene (C), and a front contact layer including indium tin oxide (ITO). The solar cell module achieves a current density (J) of greater than or equal to 20 milliamperes per square centimeter (mA/cm) at an open-circuit voltage (V) of 0.94 volts (V).
