Opposition Focuses on Nominees' Ethical Lapses at Confirmation Hearings

Choi You Sun has the details.
Report: At a confirmation hearing on Tuesday, the main opposition People Power Party(PPP) grilled Science Minister nominee Lim Hye-sook, who faces allegations of taking her family along on state-funded overseas business trips.
The PPP urged the nominee to resign, accusing her of being unable to separate her personal life from her public duties.
Struggling to defend the nominee, the ruling Democratic Party(DP) said her family accompanying her on official trips jars with public sentiment.
Lim apologized for allowing her two daughters to stay in her state-funded hotel rooms, but added that she had personally paid for all the rest of their travel expenses. ....

Researchers improve efficiency of next-generation solar cell material - Sonnenseite - Ökologische Kommunikation mit Franz Alt

Researchers improve efficiency of next-generation solar cell material
Reducing internal losses could pave the way to low-cost perovskite-based photovoltaics that match silicon cells’ output.
Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives.
Now, a new approach to the design of perovskite cells has pushed the material to match or exceed the efficiency of today’s typical silicon cell, which generally ranges from 20 to 22 percent, laying the groundwork for further improvements. ....

Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives.
Now, a new approach to the design of perovskite cells has pushed the material to match or exceed the efficiency of today’s typical silicon cell, which generally ranges from 20 to 22 percent, laying the groundwork for further improvements.
By adding a specially treated conductive layer of tin dioxide bonded to the perovskite material, which provides an improved path for the charge carriers in the cell, and by modifying the perovskite formula, researchers have boosted its overall efficiency as a solar cell to 25.2 percent a near-record fo ....
