Multicrystalline and Back Contact Buried Contact Silicon Solar Cells Dissertation

Physical model of back line-contact front-junction solar cells

All-back-contact ultra-thin silicon nanocone solar cells with 13.7% power conversion efficiency.

Thinner Si solar cells with higher efficiency can make a Si photovoltaic system a cost-effective energy solution, and nanostructuring has been suggested as a promising method to make thin Si an effective absorber. However, thin Si solar cells with nanostructures are not efficient because of severe Auger recombination and increased surface area, normally yielding <50% EQE with short-wavelength l...

Copper phthalocyanine based Schottky diode solar cells

Copper phthalocyanine (CuPc)/Aluminum (Al) Schottky diode solar cells were studied. The thickness of the CuPc layer was varied from 15 nm to 140 nm. Short circuit current densities (Jsc) increased with thickness from 0.042 mA/cm at 15 nm to 0.124 mA/cm at 120 nm reaching saturation at that level. Open circuit voltages (Voc) increased from 220 mV at 15 nm to 907 mV at 140 nm. Analysis of the cur...

Effect of Surface Passivation on Si Heterojunction and Interdigitated Back Contact Solar Cells

Silicon surface passivation of hydrogenated silicon (Si:H) thin films deposited by RF and DC plasma process was investigated by measuring effective minority carrier lifetime (τeff) on Si <100> and <111> wafers and correlated with the silicon heterojunction (SHJ) cell performances in front emitter structure and interdigitated back contact (IBC) structure. Excellent surface passivation (τeff > 1 ...
