High-performance,cost-effective hole-transport materials(HTMs)are greatly desired for the commercialization of perovskite solar cells(PVSCs).Herein,two new HTMs,TPA-FO and TPA-PDO,are devised and synthesized,which have a donor-acceptor-donor(D-A-D)type molecule design featuring carbonyl group-functionalized arenes as the acceptor(A)*** carbonyl group at the central core of HTMs can not only tune frontier molecular orbital(FMO)energy levels and surface wettability,but also can enable efficient surface passivation effects,resulting in reduced recombination *** employed as HTMs in inverted PVSCs without using dopant,TPA-FO with one carbonyl group yields a high power conversion efficiency(PCE)of 20.24%,which is among the highest values reported in the inverted PVSCs with dopant-free *** importantly,the facile one-step synthetic process enables a low cost of 30 USD g^(-1) for TPA-FO,much cheaper than the most studied HTMs used for high-efficiency dopant-free *** results demonstrate the potential of D-A-D type molecules with carbonyl group-functionalized arene core in developing the low-cost dopant-free HTMs toward highly efficient PVSCs.

Self-assembled molecules(SAMs) have shown great potential in replacing bulk charge selective contact layers in high-performance perovskite solar cells(PSCs) due to their low material consumption and simple processing. Herein, we design and synthesize a series of donor-acceptor(D-A) type SAMs(MPA-BTCA, MPA-BT-BA, and MPA-BT-RA, where MPA is 4-methoxy-N-(4-methoxyphenyl)-N-phenylaniline;BT is benzo[c][1,2,5]-thiadiazole;CA is 2-cyanoacrylic acid, BA is benzoic acid, RA is rhodanine-3-propionic acid) with distinct anchoring groups, which show dramatically different properties. MPA-BTCA with CA anchoring groups exhibited stronger dipole moments and formed a homogeneous monolayer on the indium tin oxide(ITO) surface by adopting an upstanding self-assembling mode. However, the MPA-BT-RA molecules tend to aggregate severely in solid state due to the sp~3 hybridization of the carbon atom on the RA group, which is not favorable for achieving a long-range ordered self-assembled ***, benefiting from high dipole moment, as well as dense and uniform self-assembled film,the device based on MPA-BT-CA yielded a remarkable power conversion efficiency(PCE) of 21.81%.Encouragingly, an impressive PCE approaching 20% can still be obtained for the MPA-BT-CA-based PSCs as the device area is increased to 0.80 cm^(2). Our work sheds light on the design principles for developing hole selecting SAMs, which will pave a way for realizing highly efficient, flexible, and large-area PSCs.

In recent years, the incorporation of sustainable energy resources such as wind power has had a significant impact on the stability of microgrids. In this context, our research introduces a proficient method for load frequency regulation utilizing deep reinforcement learning(DRL). Firstly, a two-area interconnected microgrid frequency control model is constructed, including wind power generation, reheat steam turbines, generators and loads. Secondly, the proposed method uses a soft actor critic(SAC)with a double Q-network to tailor the parameters of the proportional integral derivative(PID) controller, to train a DRL agent to obtain optimal controller parameters for this two-area interconnection, and we used the area control error(ACE) as the controller's input to reduce fluctuations in both grid frequency and interconnection line power flows. Furthermore, we designed a reward function via the square of the ACE to obtain the best-suited parameters for the controller. Finally, the trained controllers are tested under step load disturbance and random load disturbance, verifying that the designed SAC-PID controller provides improved frequency control performance for microgrids compared with the classical PID controller and the PID controller optimized through the particle swarm optimization(PSO) algorithm.
