Highly selective contacts which allow one type of carrier (e.g. holes) to conduct and block the other type (e.g. electrons) are the key to achieving high efficiency in thin-film solar cells. Metal-insulator-semiconductor (MIS) carrier selective contacts can make a solar cell possible without a diffused p-n junction. In this work, we introduce nickel oxide (NiO) as a potential hole selective (electron...
Crystalline silicon photovoltaic (PV) industry is growing at an average rate of ~ 15%. Continuing carbon-based fuel depletion in combination with increasing green house effects will continue to add to this robust growth trend. Conservative estimates indicate that PV market will reach ~ 100 GWp/year before the year 2020. In order to sustain such production levels, impact on materials and supplies supporting...
