Clean technology

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

MIT engineers have developed a design for a system that efficiently harnesses the sun’s heat to split water and generate hydrogen.

MIT design would harness 40% of the sun’s heat to produce clean hydrogen fuel
