The p-type base of a crystalline silicon solar cell, 300μm wide, with an electron diffusion length of 400μm, has a perfectly passivated rear surface, with a zero surface recombination velocity. What is the probability that an electron generated near the back surface is collected at the junction?
WebOct 3, 2024 · In this work, we discover that the charge collection efficiency in tin-based PSCs is limited by a short diffusion length of electrons. Adding 0.03 molar percent of cadmium ions into tin-perovskite precursors reduce the background free hole concentration and electron trap density, yielding a long electron diffusion length of 2.72 ± 0.15 µm.
