In the third article in a series, pv magazine editor Pilar Sánchez Molina and industry experts continue their discussion on the challenges and opportunities created by new panels with power output exceeding 500 W.

Scientists in China have developed an organic module with an area of 18 cm2 based on a non-fullerene acceptor called DTY6. The device has a certified efficiency of 13.98%, but when a non-halogen solvent was used, it even reached 16.1%.

A new study by the CEEW Centre for Energy Finance assesses China’s advantages over India, but presents ways for the South Asian nation to build a competitive PV manufacturing sector.

In the first article of a series, pv magazine editor Pilar Sánchez Molina analyzes with industry experts challenges and opportunities created by new panels with power output exceeding 500 W.

According to a British-Swedish research team, the down‐shifting process for solar glass manufacturing can be improved through the use of two dopant cations that produce no absorption bands. The doping with these compounds is said to reduce the UV transmission while also keeping the glass free from absorption in the visible and near-infrared ranges.

The solar cell calibration laboratory ISFH CalTeC has certified the efficiency of the cell, which was made with a standard M2 wafer.

Chinese monocrystalline PV module manufacturer Longi has yet to join the race to produce solar panels with power outputs above 600 W. The decision is line with a clear strategy, a company spokesperson told pv magazine. Outstanding issues for these moduels, according to the manufacturer, include low cell manufacturing yield, system compatibility, concerns about module transport, and hotspot-related failure risks, as well as the need for mechanical loading tests.

Chinese polysilicon manufacturer Daqo has secured a long-term supply agreement with PV equipment provider and monocrystalline wafer manufacturer Wuxi Shangji Automation, Shanxi Coal International Energy Group has unveiled a plan to set up a 10 GW heterojunction solar cell production fab and Longi has held its wafer prices.

Trina Solar has made a PV cell by directly applying the unmodified i-TOPCon process, originally developed for Cz mono wafers, to cast n-type quasi-mono silicon wafers. It claims the average efficiency, tested in-house with a calibrated reference cell, is 22.98%.

Researchers from the United States have used new passivated contact architectures to demonstrate a screen-printed silicon heterojunction solar cell on 40 micron thick standalone wafers.
