Dual passivation tech for 20.14%-efficient perovskite solar cell
Europium ions have been used by Chinese researchers to passivate both the perovskite and electron transport layer (ETL) films of a MAPbI3 perovskite solar cell. As a result, the device’s efficiency was raised by approximately 1.5%. The dual passivation approach also achieved an increase in the cell’s fill factor and open-circuit voltage.
Boosting bifacial panel efficiency with albedo ground covers: Field test results
Tests by 7X Energy show that ground cover material showed promise, but projects will likely still need to prove the long-term durability, degradation rates, and validation of installation labor and O&M.
Chinese PV Industry Brief: Another huge glass order and new profit forecasts
Module maker Risen has agreed to buy 34 GW of solar glass from Flat Glass Group (FGG). Both Trina and Goodwee announced strong profit growth for 2020.
Inverted perovskite solar cell with transition metal carbides achieves 19.2% efficiency
A Russian-Italian research group has developed a two-dimensional transition metal carbide, known as MXenes, to collect photocurrent in perovskite cells. The cells were built with an inverted configuration and are based on a nickel(II) oxide hole transporting layer. The scientists claim that the doping technique allowed them to increase the efficiency of the cell by more than 2%.
Mini perovskite solar module with 14.55% efficiency
The 5x5cm device was developed by a Japanese research group. The thickness of the perovskite films was increased to reduce defects and pinholes and this was achieved by adding ammonium chloride to the lead iodine solution used in the formation of the films. The device was able to work for 1,600 hours at more than 80% of this efficiency.
Boeing brings more PV power to NASA International Space Station
Six new arrays with a combined capacity of 120 kW will be installed on the International Space Station starting from this year. The panels will be brought to the station with the SpaceX Dragon cargo spacecraft during three resupply missions. The installation of each solar array will require two spacewalks.
GCL on verge of cross default over $500m senior notes
The polysilicon manufacturer yesterday extended the deadline for postponing settlement of the investments until Friday – with the notes set to expire on Saturday.
Satellite-derived datasets to measure ground albedo for bifacial PV
A researcher from the NREL has set up a series of datasets of measured ground albedo values using measurement network data in the U.S. and data contributed by the PV industry. The measured albedo datasets are intended to help developers of ground-mounted PV projects in making a choice between monofacial and bifacial panels.
