Tunnel Oxide Passivated Contact Structure for High Efficiency Solar Cell and Module Applications
Chun-Chieh Lo;Han-Chen Chang;Bo-Cheng Kung;Sung-Yu Chen;Chorng-Jye Huang

An advanced structure composite of poly-Si/ tunnel SiO2 as passivation contact has been developed and realized for solar cell applications. The passivation result with implied open circuit voltage (iVOC) of 726 mV and carrier lifetime of 5004 μs were examined. By applying this passivation structure to c-Si photovoltaics, Tunnel Oxide Passivated Contact (TOPCon) solar cells were developed and revealed a promising result with efficiency >23%. The module made by these TOPCon solar cells with high performance of 20.7% efficiency and 352W power was obtained.

ITO free Semi-Transparent metal thin film electrode with low sheet resistance grown on thin Bathocuproine layer for Optoelectronic devices
Anindya Sundar Jana;Sajal Biring

Here, we have fabricated an efficient organic photovoltaic device with novel small- molecular donor/ acceptor on an ITO-free electrode. The ITO-free device shows its potential to replace the conventional ITO-based electrode

Dielectric Barrier Discharge Jet Processed TiO2 Nanoparticle Layer for Perovskite Solar Cells
Jui-Hsuan Tsai;Mohana Sruthi;Cheng-Che Hsu;Jian-Zhang Chen;I-Chun Cheng

The nanoparticle-based TiO2 electron transport layer of n-i-p perovskite solar cells is treated with the non-vacuum dielectric barrier discharge jet using He as the carrier gas. The photoelectrical conversion efficiency is enhanced from 13.92% to 14.43% for the on-glass cell and from 12.30% to 13.66% for the on-PEN cell.

Efficiency Enhancement of Si-based Ultra-thin Solar Cell by Cascading with Dilute-Nitride Ga(N)AsP
Yen-Ju Lin;David Jui-Yang Feng;Tzy-Rong Lin;Mao-Kuen Kuo

This study has numerically evaluated the performance of Si-based ultra-thin solar cell can be enhanced by cascading a dilute-nitride Ga(N)AsP. The result shows, in case of thickness = 11.5 micron, the efficiency can be improved from 12.7% to 18.9%. In case of efficiency = 13.1%, we can significantly reduce thickness from 15 micron to 5.5 micron.

Plasmonic Effect of Bimetallic Au-Cu Alloy Nanoparticles on Indoor Performance of Organic Photovoltaics
Gautham Kumar;Fang Chung Chen

Bimetallic Au-Cu alloy nanoparticles (NPs) are incorporated in the anodic buffer layer to enhance the performance of organic photovoltaic devices (OPVs). Localized surface plasmon resonance (LSPR) induced by the NPs effectively increase the power conversion efficiency (PCE) both under 1 sun illumination condition and indoor light sources (LED and TL5).
