Korean researchers achieve world record efficiency of 23.64% for flexible perovskite-CIGS tandem solar cell
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.
Tanzanian utility issues EPC tender for 100 MW solar plant
Tanzania Electric Supply Co. Ltd. (Tanesco) is seeking engineering, procurement and construction (EPC) contractors for a 100 MW PV facility to be built in the country’s Shinyanga Region.
Scientists testing perovskite-silicon tandem solar cells with interdigitated back contacts
A research team in Iran has designed a four-terminal perovskite-silicon tandem solar cells with a 19.3%-efficient bottom heterojunction cell and a 12.7%-efficient perovskite top cell. Both subcells were conceived to have interdigitated back contacts, with the top cell reportedly helping to improve the tandem device’s light-trapping and efficiency.
New simulation framework achieves higher dual land use efficiency in agrivoltaics
Researchers in Italy have conceived new agrivoltaic modeling for agrivoltaics that includes crop yield response curves for multiple crops. Once the electricity production coming from the PV modules is also assessed, the performance metrics for the agrivoltaic system as a whole are obtained.
International PV module pricing may rise to $0.11/W by year end
International PV module prices, driven by Chinese averages, will likely rise from $0.08/W to $0.10/W today to $0.11/W by the end of 2025 and potentially $0.13/W by 2027, says Clean Energy Associates (CEA), noting that heterojunction and back-contact technologies now make up 12% of global module capacity.
Water-based electrically conductive adhesives for shingled solar modules
Scientists in Turkey have conceived new solar module electrically conductive adhesives based on silver microflakes and optimized polymeric additives. The proposed adhesives were found to increase electrical conductivity, adhesion strength, and reliability under real-world operating conditions.
Navien unveils 4-17 kW air-source heat pump for residential applications
The South Korean heating specialist said its new heat pump system can achieve a seasonal coefficient of performance of up to 4.79 and flow temperatures of up to 75 C.
Semi-translucent solar window based on concentrated photovoltaics
Researchers in Spain have designed a PV window that performs active daylighting management while producing electricity. The system can reportedly ensure high power density, as it harvests all the direct light incident on the aperture area.
Mitsubishi Electric debuts new residential air-source heat pumps
The manufacturer has expanded its Ecodan R290 heat pump series with three new products. The systems use propane (R290) as the refrigerant and can purportedly deliver flow temperatures of up to 75 C.
Fire damages PV system on school in Belgium
A fire damaged around 100 of the 160 solar panels on the roof of Don Bosco school in Halle, Belgium. Firefighters quickly extinguished the blaze, and no injuries were reported.
