Stacking perovskite solar cells onto crystalline silicon bottom cells in a monolithic tandem configuration enables power-conversion efficiencies (PCEs) well above those of their single-junction counterparts. However, state-of-the-art wide-band-gap pe... Read More about 28.2%-efficient, outdoor-stable perovskite/silicon tandem solar cell.

Carrier recombination at the interface between charge extraction layers and the perovskite photoactive layer in solar cells reduces the quasi-Fermi level splitting (QFLS) and hence the device's open-circuit voltage (VOC). Distinguishing between inter... Read More about Charge Carrier Recombination at Perovskite/Hole Transport Layer Interfaces Monitored by Time-Resolved Spectroscopy.

Advancing non-fullerene acceptor (NFA) organic photovoltaics requires the mitigation of the efficiency-limiting processes. Acceptor end-group and side-chain engineering are two handles to tune properties, and a better understanding of their specific...
