Finding a way to boost efficiency of CIGS solar cells

CIGS (copper-indium-gallium-selenide) solar cells are compound thin-film solar cells and the most established alternative to silicon solar cells. Solar conversion efficiencies of over 20% have recently been achieved in CIGS ...

Field-effect transistors get a boost from ferroelectric films

(Phys.org) —As microelectronics get smaller and smaller, one of the biggest challenges to packing a smartphone or tablet with maximum processing power and memory is the amount of heat generated by the tiny "switches" at ...
