AI Unveils Chemical Secrets for Solar Energy: Turning the Black Box Transparent

The schematic illustrates the structural benefits of three bithiophene-based hole transport materials (TP-H, TP-OMe, and TP-F) designed for perovskite solar cells (PSCs). These materials feature large steric hindrance, non-covalent interactions, and passivation effects, which simplify synthesis and reduce costs. The performance comparison graph reveals that the TP-F-based PSC achieves a power conversion efficiency (PCE) of 24.01%, surpassing TP-H and TP-OMe. The device configuration diagram shows the layer structure, including the hole transport material (HTM), which contributes to the high efficiency.

Solar Cells Breakthrough: New Materials Boost Efficiency and Cut Costs

Applying a transparent Pr3+/Eu3+-doped glass-ceramic layer on top of a photovoltaic cell simultaneously protects it from damaging UV light and converts that UV radiation to visible light, thereby enhancing the light-to-energy conversion efficiency.
