Intrinsic DX Centers in Ternary Chalcopyrite Semiconductors

The conclusions of this report are: (1) intrinsic donor-type defects In{sub Cu}, Ga{sub Cu}, and V{sub Se}, and their complexes with V{sub Cu} cause metastability, but also act to limit V{sub OC}; (2) growth conditions which minimize these defects (Cu-rich/Se-rich) are very different from those currently used; and (3) overcoming V{sub OC} limitation requires to address other issues and trade-offs.

Design of Shallow p-type Dopants in ZnO

ZnO is a promising material for short wave-length opto-electronic devices such as UV lasers and LEDs due to its large exciton binding energy and low material cost. ZnO can be doped easily n-type, but the realization of stable p-type ZnO is rather difficult. Using first-principles band structure methods the authors address what causes the p-type doping difficulty in ZnO and how to overcome the p-type doping difficulty in ZnO.

Do the Defects Make it Work? Defect Engineering in π - Conjugated Polymer Films and Their Solar Cells

The summaries of this report are: (1) charged defects produce 10{sup 15}-10{sup 17} cm{sup -3} free carriers; (2) treatment with nucleophiles decreases p{sub f} and {sigma} while treatment with electrophiles does not change p{sub f} but increases {sigma}; (3) both treatments increase {mu}{sub p}, L{sub ex} and stability against photo-degradation; (4) charged defects can improve OPV by increasing conductivity and creating interfacial electric fields but they hurt {mu}{sub p}, L{sub ex} and chemical stability; and (5) a better way--synthesize materials without covalent defects and dope with purposely added, bound dopants.

Direct Comparison of Inverted and Non-inverted Growths of GaInP Solar Cells

The motivation for this presentation is that growing inverted cells may enable technological advances in solar cell fabrication, leading to higher efficiencies. Differences in dopant diffusion during inverted vs. upright growths may lead to differences in atomic depth profiles; changes in carrier concentrations; higher contact resistance and lower overall performance. This presentation summarizes that excellent performance is achievable in both upright and inverted configurations with proper consideration; subtle differences in depth profile QE and JV between upright and inverted growths due to dopant diffusion; and GaInAsN contact layer is resilient to length annealing and more work is necessary to determine why.
