New PV cell architecture creates resistively bounded subcells

Solar Inventions, the winners of the first American-Made Solar Prize, plan to commercialize their newest product, which is claimed to reduce silver content and increase module power, while potentially saving manufacturers up to $1 million per year.

New protocols identify solar cell failures during production

Two new pass/fail protocols are said to be able to separate cells which present high hot-spot possibility, show high current leakage and demonstrate intermediate behavior. The sorting technique relies on a manual solar simulator, an infrared camera and a tool to measure isolation.

New equipment for solar cell metallization

The system can metallize the front and back sides of silicon solar cells with unprecedented precision and speed, Fraunhofer ISE said. The technology is also suitable for components such as printed circuit boards or chip cards.

New production equipment for large-area perovskite solar cells

National Taiwan University and Taiwanese PV production equipment provider E-Sun Precision Industrial Co. have developed equipment to produce different kinds of perovskite cells with varying chemical compositions. The first trials achieved 14.3% conversion efficiency rates.

Panasonic suspends work at Tesla’s Nevada fab as carmaker’s California and New York gigafactories pause

Tesla’s Nevada operation is still open for business, though. The EV and battery maker has assured the market its cash position is strong enough to weather an “extended period of uncertainty”.

Finnish solar manufacturer extends vital fundraising exercise again

Valoe Corporation has extended its €3.5m convertible bonds issuance but with investors fleeing to safe havens and Lithuania yesterday announcing COVID-19 quarantine measures, hopes of getting cell manufacturing off the ground in Vilnius this month appear unrealistic.

PV industry silver demand to fall slightly

Trade body the Silver Institute says silver demand in the solar industry will dip slightly this year but remain near to previous record highs. Silver paste consumption for PV has been reduced due to advances in metallization techniques.

Tongwei to open new 30 GW cell fab in Sichuan

Construction of the $2.87 billion factory is scheduled to start in March and manufacturing activity should be launched in 2021.
