High-performance solar cells with lower cost | NextBigFuture.com

Chinese researchers have developed solar cells which are high efficiency and lower cost. Nano Energy Journal – Modulation-doped ZnO as high performance electron-selective layer for efficient silicon heterojunction solar cells Highlights • The Li-doped ZnO (Li-ZnO) layer was fabricated by a simple, mild and efficient solution process, and the work function was tuned precisely in a relative large range (from 4.15 to 3.85 eV). • The contact resistivity (ρc) was dramatically decreased from 100 mΩ cm2 to 18 mΩ·cm2 for n-Si/Li-ZnO/Al structure with optimized Li concentration. • Remarkable efficiency of 15.1% and open-circuit voltage of 643 mV, for the solution-proceeded PEDOT: PSS/Si heterojunction solar The post High-performance solar cells with lower cost appeared first on NextBigFuture.com.
