||14882831||FUTURE EVE TECHNOLOGY Co, Ltd||Isao OKAMURA|
A provided cover glass for a solar cell panel has excellent transparency, and minimal incidence so-called “glass surface turbidity” due to reactions with components contained in a glass substrate. The cover glass for the solar cell panel comprises: the glass substrate including a surface; and a transparent protective film containing zinc telluride for coating the surface. Particularly, in the cover glass for the solar cell panel, the transparent protective film is preferably formed by bonding the zinc telluride with silica binders. Such a transparent protective film has excellent transparency, and reactions of the contained zinc telluride inhibit the surface of the glass substrate, which is a base of the solar cell, from becoming turbid.

20160035919 QUANTUM DOT SOLAR CELL PERFORMANCE WITH A METAL SALT TREATMENT||US||04.02.2016|
||14270141||Samsung Electronics Co., Ltd.||Su Kyung Suh|
The performance of lead sulfide quantum dot (QD) photovoltaic cells is improved by exposing a QD layer to a solution containing metal salts after the synthesis of the QDs is completed. The halide ions from the salt solution passivate surface lead (Pb) sites and alkali metal ions mend Pb vacancies. Metal cations and halide anions with small ionic radius have high probability of reaching QD surfaces to eliminate surface recombination sites. Compared to control devices fabricated using only a ligand exchange procedure without salt exposure, devices with metal salt treatment show increases in both the form factor and short circuit current of the PV cell. Some embodiments comprise a method for treatment of QDs with a salt solution and ligand exchange. Other embodiments comprise a photovoltaic cell having a QD layer treated with a salt solution and ligand exchange.

A solar cell can include a silicon layer formed over a silicon substrate. The silicon layer can have a P-type doped region and an N-type doped region. Portions of the silicon layer can have a grain size larger than other portions of the silicon layer. For example, larger grains of the silicon layer formed within a depletion region between P-type and N-type doped regions can minimize recombination loss at the P-type and N-type doped region boundaries and improve solar cell efficiency.
