讲座摘要:

Minimizing energy loss is a key aspect to transcend the current limitations on the performance of organic and perovskite photovoltaics (OPV & PVSC). Our recent study reveals that the fully-fused rigid molecular acceptors are not only intrinsically highly luminescent but also meets the criteria in achieving intrinsically radiative recombination within the blend, which is a key step in moving towards new OPV materials and selection criteria if they are to approach the theoretical efficiency limits. In addition to the development of OPV, composition and interface engineering have been explored to dramatically improve the efficiency and long-term operational stability of the PVSC. Moreover, a very innovative approach has also been developed to combine both efficient charge extraction and the ability to trap decomposed Pb-containing perovskites into one material to address the most challenging environmental contamination issue for the commercialization of PVSCs.

This talk will be divided into three parts:

(1) Advances in developing novel non-fullerene acceptors to achieve record-high certified efficiency (17.5%) with low photovoltage (Voc) loss;

(2) Progress of achieving the highest efficiency (23.1%) in inverted perovskite solar cells (PVSCs) through smart engineering of the interfaces;

(3) Demonstration of the simultaneous achievement of high PCE (>22%), excellent operational stability (85°C at MPP for 1000h under 1 Sun illumination), and the ability to capture degraded Pb-containing by-products by employing 2D metal-organic frameworks (2D-MOF) as a charge extraction layer in PVSCs.
