A fresh perspective on the role of band bending, and related contributors, in light-driven production of electricity and chemicals

Key Points

• This research aims to explore how band bending and other factors affect light-driven production in semiconductors.
• Analyzed net charge distributions in a pn-homojunction semiconductor.
• Examined the effects of uniform light absorption on charge transport rate.
• Investigated the relationship between electric fields and potentials in equilibrated conditions.
• Found that electric fields and potentials match the initial nonequilibrium conditions in uniform light absorption.
• Demonstrated that uniform light absorption leads to consistent charge distributions.
• Revealed insights into the interactions between band bending and charge transport.
