The new edition of the International Technology Roadmap for Photovoltaic (ITRPV), published this week, reports that average PV module prices last year dropped by 33% compared to the end of 2023.

The Vietnamese authorities released the feed-in tariff levels for ground-mounted and floating PV plants, with or without storage.

Conceived for industrial applications, the Danae heat pump system is available in 10 versions with cooling capacities ranging from 22.1 kW to 156.9 kW and heating capacities spanning from 24.8 kW and 181.6 kW.

Danish researchers have analyzed fundamental material properties of selenium solar cells and have found their potential is higher than generally believed. They used carrier-resolved photo-Hall analysis to address discrepancies and reproduce experimental current-voltage and external quantum efficiency measurements.

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses the so-called phase disposition level-shifted pulse width modulation (PDLSPWM) control technique to operate the switches in the circuit “effectively.”

The European Bank for Reconstruction and Development (EBRD) has kicked off a tender for 28 MW of solar projects in Bosnia and Herzegovina under state utility EPBiH’s plan to deploy 195 MW of PV capacity.

Solyco is developing a new low-temperature technology for the interconnection of solar cells. It consists of a round copper core with a diameter of 280 μm that is covered by a very thin layer of silver for corrosion protection and then surrounded by a 40 μm coating of an electrically conductive thermoplastic.

The system consists of a reversible compressor connected to a storage unit that can be installed indoors or outdoors. The compressor must be connected to the solar panels, with the whole system being controlled by an application that optimizes self-consumption.

The Chinese manufacturer said its new heat pump system can continuously and stably provide hot water up to 75 C. At a temperature between 35 C and 55 C, the new product can reportedly achieve a seasonal coefficient of performance (SCOP) of 4.6 to 5.23, with COP values ranging from 3.86 to 5.63.

Scientists at the Korea Institute of Energy Research claim to have achieved the highest efficiency ever reported for a perovskite-CIGS tandem solar cell with flexible, lightweight architecture. The device was also found to achieve “excellent” durability.
