A group of researchers in Iran has analyzed the coefficient of performance and the energy consumption of a solar-assisted heat pumps and an air-source heat pumps and has found that three factors are crucial to determine their annual performance – irradiance changes, ambient temperature, and wind speed.

New research from Iran shows that PV installations linked to battery storage may help prevent accidents and increase safety in nuclear power plants by acting as an emergency load. The scientists proposed a system design that considers both technical and economics factors.

Iranian researchers have improved perovskite solar cell efficiency by using a single-walled carbon nanotube as a hole transport layer surrounded by lead sulfide colloidal quantum dots.

Researchers in Iran have identified new ways to design perovskite quantum dot solar cells via a series of simulations. They investigated, in particular, how the perovskite absorbers can be gauged in order to enhance their electro-optical properties.

Researchers in Iran have designed a new light trapping (LT) structure for perovskite solar cells that reportedly achieves optimal light absorption without impacting the electrical properties of the cells. The key element of the device is an anti-reflector layer based on silicon dioxide (SiO2) that improves light harvesting and charge extraction performance.

An international research team has crafted an innovative solar cell design. By employing a top absorber consisting of methylammonium lead iodide (MAPbI3), a lead-halide perovskite, and a bottom absorber composed of FA0.5MA0.5Pb0.5Sn0.5I3, a perovskite material, the cell maximizes light absorption across a broad spectrum.

A research team has studied the potential of using concentrating photovoltaics in agriculture and found that it offers advantages in terms of energy yield and de-shading compared to conventional photovoltaics. However, the higher costs must be carefully considered.

Iranian researchers have looked at how ultrasonic thermoelectric generators could be used to lower the operating temperature of solar modules. Their new system can generate cold steam via ultrasonic piezoelectrics in a simple batch system.

An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.

An Iranian research group has developed a system that combines photovoltaic-thermal modules with organic Rankine cycle, a proton exchange membrane electrolyzer, and liquefied natural gas. The ideal system has an exergy efficiency of 16.24%, a cost rate of $4.48 per hour, and 33.32 kW of net electrical power.
