Thin Film Solar Cells from Nanocrystal Inks of Quaternary Chalcogenides
The creation of a suitable inorganic colloidal nanocrystal ink for use in a scalable coating process is a key step in the development of low-cost thin film solar cells. We have developed an innovative method of using copper indium gallium disulfide (CIGS) nanocrystals as the building block for the fabrication of bulk CIGSSe thin films. The CIGS nanocrystal ink solution is applied directly on va...
متن کاملChemical composition tuning in quaternary p-type Pb-chalcogenides--a promising strategy for enhanced thermoelectric performance.
Recently a significant improvement in the thermoelectric performance of p-type ternary PbTe-PbSe and PbTe-PbS systems has been realized through alternating the electronic band structure and introducing nano-scale precipitates to bulk materials respectively. However, the quaternary system of PbTe-PbSe-PbS has received less attention. In the current work, we have excluded phase complexity by fabr...
متن کاملQuaternary chalcogenides BaRE2In2Ch7 (RE = La-Nd; Ch = S, Se) containing InCh5 trigonal bipyramids.
Eight new quaternary chalcogenides BaRE2In2Ch7 (RE = La-Nd; Ch = S, Se) have been prepared by reactions of BaCh, In2Ch3, RE, and Ch at high temperatures. They adopt orthorhombic structures (space group Pbam, Z = 2; a = 11.6300(8)-11.5895(7) Å, b = 12.4202(9)-12.3001(8) Å, c = 4.0689(3)-4.0028(2) Å for the sulfides; a = 12.1515(6)-12.1358(10) Å, b = 12.9367(7)-12.8510(11) Å, c = 4.1966(2)-4.1363...

متن کاملRevisiting some chalcogenides for thermoelectricity.
Thermoelectric materials that are efficient well above ambient temperature are needed to convert waste-heat into electricity. Many thermoelectric oxides were investigated for this purpose, but their power factor (PF) values were too small (∼10-4 W m-1 K-2) to yield a satisfactory figure of merit zT. Changing the anions from O2- to S2- and then to Se2- is a way to increase the covalency. In this...
