New tech may bring heterojunction solar cells based on p-type wafers closer to mass production

An Australian-Russian research group has developed a silicon heterojunction solar cell based on p-type gallium-doped wafers with an efficiency of 22.6% and an improved stability. The scientists are convinced that these wafers may become a mainstream solution for the SHJ segment within the next decade.


South Korea allocates 2 GW in PV tender, final average price drops to $0.118/kWh

Selected projects will be awarded a fixed rate under a 20-year contract under the country’s renewable energy certificate (REC) scheme and will sell electricity to local power distributors.

Testing field for PV noise barriers

Two testing facilities for photovoltaic noise barriers are being built by a Belgian consortium. Their creators want to assess different PV technologies, reduce costs and plan large scale projects in Belgium, where land and policy constraints make the construction of ground-mounted PV plants almost impossible.

Another 70 MW of floating solar goes online in the Netherlands

BayWa re commissioned two floating PV facilities which it claims are the largest in Europe and outside Asia.


Solar module for floating PV from Hyundai

The bifacial panel has a power output of up to 485 W and an efficiency of up to 21%. It relies on a transparent backsheet and is encapsulated with polyolefin elastomer (POE).


Chemical bath deposition for 21.7%-efficient perovskite solar cell based on tin oxide films

The cell was used to build two perovskite solar modules with a size of 5x5cm and 10x10cm, respectively, and with efficiencies of 15.62% and 11.80%.

China wants to test vanadium redox flow batteries

A 125 kW/500kWh storage unit will be tested by China’s National Photovoltaic and Energy Demonstration Experimental Center. The storage system will be provided by Canadian specialist VRB Energy.

India tenders 1.2 GW solar in Karnataka

Solar Energy Corp. of India has given developers until Sept. 3 to bid for 1.2 GW of solar projects that will be set up on a build-own-operate basis in the state of Karnataka.


First lessons learnt from offshore pilot PV system in North Sea after 18-month operation

The 50 kW modular PV system started operating at the end of November 2019. According to its developer, Dutch start-up Oceans of Energy, power production after 18 months of operations is in line with expectations. The installation had to withstand several storms and waves with a height of up to 10 meters.
