‘Extraordinary week’ capped off with PV-IPCEI launch in Brussels
The PV-IPCEI event hosted by the European Solar Manufacturing Council (ESMC) took place on May 20 in a narrow wood-paneled room of Brussels’ Art Deco Residence Palace.
Heterojunction solar cell with 25.18% efficiency, 85.42% fill factor
Researchers in China have fabricated a heterojunction solar cell with a 244.63 cm2 Czochralski n-c-Si wafer. They used light soaking to improve the dark conductance of the hydrogenated amorphous silicon films.
Upcycling silicon waste from end-of-life solar panels into thermoelectrics
Researchers in Singapore have developed a new technique in which polycrystalline silicon is pulverized into powder and pelletized into ingots. The process relies on spark plasma sintering to dope the silicon with germanium and phosphorus.
Chinese PV Industry Brief: China’s cumulative PV capacity tops 322 GW
In other news, Zhonghuan Semiconductor announced it will begin selling 210 mm n-type wafers and the local government in Zhejiang Province said it wants to deploy another 12.4 GW of new PV by 2024.
EBRD due diligence efforts highlight importance of supply chain transparency
Evidence of the extent to which the European Bank for Reconstruction and Development (EBRD) is investigating public allegations made against PV manufacturers has been highlighted in its due diligence processes. As a multilateral financial institution supporting renewable projects in many countries, smaller banks may mirror the EBRD’s efforts. pv magazine spoke with PI Berlin Managing Director Asier Ukar about the current state of solar supply-chain traceability systems.
Novel mounting structure for PV systems on thermoplastic polyolefin roofs
Mibet has developed a new PV mounting structure made of stainless steel and aluminum, providing a perfect match between TPO fixing supports and trapezoidal metal rooftops. The apparatus includes a rail, two clamp kits, a support kit, the TPO roof fixing support, and a TPO cover plate.
