All-small-molecule organic solar cells with high photovoltaic performance and low non-radiative energy losses ≤ 0.2 eV.

The efficiency enhancement mechanism of the alkali-treated Si nanowire (SiNW) solar cells is discussed and analyzed in detail, which is important to control the useful photovoltaic process. All the results demonstrate that the photovoltaic performance enhancement of alkali-treated SiNW device steps from the formation of the good core-shell heterojunction, which consequently enhances the junctio...

Project Title: Spin Injection and Its Effects on Losing Action in Conjugated Polymers This project specifically focuses on two particular topics: (i) developing organic spintronics for magnetically controlling constructive and non-constructive interaction of excited processes towards lasing applications and (ii) elucidating singlet and triplet photovoltaic processes towards improving photovolta...

A novel immobilized fullerene–single wall carbon nanotube (C60–SWCNT) complex was synthesized via a microwave induced functionalization approach. It has been used as a component of the photoactive layer in a bulk heterojunction photovoltaic cell. As compared to a control device with only C60, the addition of SWCNTs resulted in an improvement of both the short circuit current density JSC and the...

Albert Einstein discovered the theoretical foundations on which photovoltaic cells are based a hundred years ago — it was a spin-off from his annus mirabilis. Half a century ago, Bell labs built solar cells out of silicon, which soon came to be used in space flight. But the real breakthrough in solar cells was neither theoretical, nor experimental. It was a simple pecuniary reward. Since the 19...
