Organic-inorganic perovskites were treated with a CsI solution to improve the photovoltaic performance and stability. Due to the formation of CsPbI3 and trap filling in Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3 perovskites by CsI treatment, the power conversion efficiency was improved to 20.48%. The CsI-treated perovskites exhibited slower degradation under heating at 180 °C than the untreated perovskites.

Herin, the successful synthesis of a bis Schiff base (L) has been achieved using 2-hydroxy-1-naphthaldehyde and 1,3-diaminoguanidine as raw materials, which was further characterized by infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance hydrogen spectrum. Moreover, spectroscopic experiments demonstrated that the probe L showed good selectivity and visual detectability for Al. Its detection limit (DL) is 2.

The hot carrier multi-junction solar cell (HCMJC) is an advanced-concept solar cell with a theoretical efficiency greater than 65%. It combines the advantages of hot carrier solar cells and multi-junction solar cells with higher power conversion efficiency (PCE). The thermalization coefficient () has been shown to slow down by an order of magnitude in low-dimensional structures, which will significantly improve PCE.

Three new bithiophene imide (BTI)-based organic small molecules, (), (), and (), with varied alkyl side chains, were developed and employed as self-assembled monolayers (SAMs) applied to NiOx films in tin perovskite solar cells (TPSCs). The NiOx layer has the effect of modifying the hydrophilicity and the surface roughness of ITO for SAM to uniformly deposit on it. The side chains of the SAM molecules play a vital role in the formation of a high-quality perovskite layer in TPSCs.

As the proportion of solar energy in the global energy mix increases, photovoltaic cells have emerged as one of the fastest-growing technologies in the renewable energy sector. However, photovoltaics utilize only a limited portion of the incident solar spectrum, resulting in significant amounts of light energy being wasted as heat. This excess heat raises the surface temperature of photovoltaic cells, which in turn reduces their overall efficiency.

The rapid expansion of solar photovoltaic (PV) power generation raises concerns regarding its impact on terrestrial ecosystems. Although the influence of PV panels on soil conditions and plant biomass is acknowledged, their effects on the assembly processes and co-occurrence networks of soil microbial communities remain understudied. Clarifying this influence is crucial for understanding the effects of photovoltaic panels on soil ecosystem functions.
