To　improve　the　transmittance　and　enhance　the　hydrophilicity　on　the　surface　of　glass,　a　aluminum-induced　method　was　used　to　prepare　the　light　trapping　structure.　The　Al　thin　films　were　prepared　by　DC　magnetron　sputter　technique.　The　effects　of　annealing　treatment　at　various　substrate　temperatures　on　the　surface　structure,　optical　properties　and　wettability　of　the　glass　were　studied.　The　glass　surface　prepared　was　observed　by　scanning　electron　microscopy　(SEM).　The　change　of　the　transmittance　of　the　glass　after　the　process　was　measured　by　the　UV-VIS　spectrophotometer.　The　wetting　property　of　the　bare　and　etching　glass　was　determined　by　the　contact　angle　instrument.　Results　show　the　different　structures　of　light　trapping　structure　can　be　prepared　by　adjusting　annealing　temperature.　The　transmittance　of　the　samples　annealed　at　150℃　reaches　94%　within　the　wavelength　range　of　480-680　nm.　The　surface　contact　angle　of　the　sample　annealed　at　200℃　decreases　to　8.6°.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
