With the aim of achieving 20% conversion efficiencies but with lower material costs, Solliance and imec have demonstrated a CZTSe (Cu2ZnSnSe4)-based thin-film solar cell (1x1cm2, AM1.5G) with 9.7% efficiency.
Multi-junction solar cells with conversion efficiencies of almost 50% could become cost effective as a result of a collaboration between equipment supplier EV Group and Fraunhofer ISE.
Employing its liquid-based dye solar cell (DSC) substrate, Dyesol claimed it had surpassed the standard IEC 61646 design qualification for PV modules, without disclosing the approved testing house.
