Summary: Greenhouse cultivation is a modern form of agriculture that aims to achieve higher yields and better crop quality through controlled environments. This study evaluates the potential of PV, STC, and PV/T solar technologies in greenhouses. PV modules show promise in meeting electrical energy demand, but shading effects can reduce photosynthetic efficiency. Dynamic shading and concentrating solar technologies offer potential solutions. Semi-transparent PV technologies and STC collectors can also be integrated into greenhouses. Overall, implementing solar technologies in greenhouses can enhance crop production and ensure sustainable energy production.

Summary: The volume of end-of-life photovoltaic panels to be managed will increase considerably over the next decade. It is becoming necessary to develop efficient recycling processes within an environmentally friendly circular economy. A delamination process using supercritical CO2 was studied for the recycling of end-of-life photovoltaic modules. The results show that SC-CO2 treatment is promising for the delamination of first generation photovoltaic modules and future generations of high efficiency perovskite-based photovoltaic modules containing ionomers. However, it is less effective for encapsulating polymers without CO2-philic groups.

Summary: The development of degradable alternative-plastic agricultural film is urgent to reduce plastic pollution. Degradable cellulosic films have shown great potential for sustainable agricultural development in a low-carbon economy, but radiative heat dissipation and poor water resistance hinder their practical application. In this study, a superhydrophobic transparent cellulosic film was developed by combining copper nanowires (CuNWs) with high reflection of mid-far infrared radiation and a hydrophobic functionalization strategy. The Cu/LC film showed increased radiation insulation ability, light transmittance, flexibility, and antimicrobial properties, providing a new way for developing degradable agricultural film.

Summary: In this study, high-performance FePV devices were obtained by directly coating partially crystallized Zn0.92-xCux(Fe0.04Li0.04)O (ZCFLO) film on a polyimide substrate using a cheap and simple dip-coating method. Enhanced carrier transportation and photovoltaic performance were achieved by introducing local ferroelectricity and the piezo-photovoltaic effect in designed ferroelectric/amorphous nanostructures, further expanding the research scope of piezo-phototronics.

Summary: Construction of a heterojunction between quantum dots and TiO2 nanowire arrays via electrostatic self-assembly is rarely reported. In this work, the surface potential of WO3 quantum dots and TiO2 nanowire arrays was changed using mercury lamp irradiation, resulting in WO3 quantum dots tightly attached to the TiO2 nanowire surface through electrostatic self-assembly. Photoelectrochemical measurements showed that the WO3 quantum dots formed a type II heterojunction with the TiO2 nanowire arrays, greatly improving the contribution of the WO3 quantum dots to the photocurrent. The self-assembled system exhibited excellent photoelectrochemical stability and significantly enhanced photocurrent density compared to the TiO2 nanowire arrays.

Summary: The study found that a vibration-mediated resonance may play a pivotal role in the charge transfer across a donor-acceptor interface in an organic solar cell. Charge transfer is significantly enhanced when the vibrational energy quanta is equal to the electronic energy loss across the interface. The ultrafast vibration-mediate resonant charge transfer process occurs within 100 fs, comparable to experimental findings.
