Development of a New Maximum Power Point Tracking Method for Power Conversion Efficiency Measurement of Metastable Perovskite Solar Cells

Electrochemistry, 2020
A new algorithm for the maximum power point tracking (MPPT) method has been developed in order to determine the maximum power (Pmax) for slow-responding metastable PV devices such as perovskite solar cells (PSCs). It is well known that such devices often

Analysis and design of the DC power supply based on solar photovoltaic power systems(基于太阳能光伏发电系统的直流电源分析与设计)

Zhejiang Daxue xuebao. Lixue ban, 2016
为解决独立光伏发电系统中太阳能转换效率低、蓄电池使用寿命短等问题，将最大功率点跟踪技术(MPPT)和蓄电池优化充放电控制策略应用到太阳能充电系统中.同时，应用以TL494为核心的推挽升压电路，降低系统对太阳光的依赖性，在没有太阳光时，系统由储存的蓄电池能量通过升压电路给负载供电.据此设计了一种以Atmega 88单片机为核心，由DC-DC充电变换器和蓄电池升压电路组成的直流电源.实验结果表明，采用MPPT充电方式可以实现对蓄电池充放电的优化管理，其平均充电效率达到了91.24%，延长了蓄电池的使用寿命 ...

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

Advanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...
