Subha Prakash Mallick Neutron Irradiation Induced Defects upon Minority Carrier Lifetime in Si Solar Cell
Subha Prakash Mallick;Durga Prasad Dash;Sandipan Mallik;Rakesh Roshan;Shrabani Mahata;Palash Das;Satya Sopan Mahato

Effects of neutron irradiation upon carrier lifetime incorporated with change in recombination rates; consequence displacement damage in Si solar cell. Radiation induced defects are analyzed with change in open circuit voltage, maximum power, and fill factor; cause non uniform rise in reverse saturation current(J0) with fall in open circuit voltage(Voc).

Wei-Jie Chang Optimized Structure with Diffractive Optical Element for Light-Splitting in Solar system
Wei-Jie Chang;An-Chi Wei;Jyh-Rou Sze

The purpose of this research is to split light into visible light and infrared light. Since the diffractive optical element (DOE) splits the light with different wavelengths to different diffraction angles, it along with other structure will be used for separating infrared and visible portions of white light.

Likarn Wang New Texturing Technique for Diamond Wire Sawn Multicrystalline Silicon Wafers
Likarn Wang;Kang-Pin Lee;Guang-I Yeh

In this study, we work out a wet chemical etching method with which surfaces of DWS multicrystalline silicon wafers can be effectively textured without using sulfuric acid and phosphoric acid and of course without using MCCE or RIE methods.

13:45 - 14:00 Paper No.  2017-FRI-S0904-O004
Forest Shih-Sen SEN Chien Observation of Charge Coupling in InGaP/InGaAs/Ge Triple-Junction Solar Cells by Electric Modulus Spectroscopy
Forest Shih-Sen SEN Chien

Electric modulus (M) spectroscopy incorporated with lasers is demonstrated to be an effective approach to investigate the electrical characteristics of the individual subcells in InGaP/InGaAs/Ge triple-junction solar cells. Charge coupling between the excited and neighboring subcells is observed, which causes the expansion of the depletion region in the latter.

14:00 - 14:15 Paper No.  2017-FRI-S0904-O005
You-Lan Li Solution Process Hybrid Solar Cell In Thin Substrate : Impact of Surface Template And Process Conditions
You-Lan Li;Pei-chen Yu

We use metal-assisted chemical etching (MACE) and rapid thermal anneal (RTA) techniques to fabricate new multi-structure on Si surface. The PCE of new multi-structure on hybrid solar cell can achieve 14.07% by reducing reflectance to 3.61% and enhancing JSC to 33.43 mA/cm2.
