Experiments on performances of nano and conventional solar PV modules involved establishing of I–V curves under tropical condition were conducted. Nano PV module based on copper indium gallium selenide and conventional PV module based on mono crystalline silicon with the same rated peak power of 5 W, recorded maximum power of 3.6 W and 3.7 W respectively at STC and irradiance of 1000 W/m2. Efficiencies of nano and conventional solar PV modules were 10.93% and 12.21%, which is slightly lower than rated STC values of 14% and 16% respectively. Deviation in power output is associated with high module temperature of about 59.1 °C. At corresponding temperature below 45 °C and irradiance of 400 W/m2, efficiency of nano module was about 5% higher than that of conventional module.

摘要

Experiments on performances of nano and conventional solar PV modules involved establishing of I–V curves under tropical condition were conducted. Nano PV module based on copper indium gallium selenide and conventional PV module based on mono crystalline silicon with the same rated peak power of 5 W, recorded maximum power of 3.6 W and 3.7 W respectively at STC and irradiance of 1000 W/m2. Efficiencies of nano and conventional solar PV modules were 10.93% and 12.21%, which is slightly lower than rated STC values of 14% and 16% respectively. Deviation in power output is associated with high module temperature of about 59.1 °C. At corresponding temperature below 45 °C and irradiance of 400 W/m2, efficiency of nano module was about 5% higher than that of conventional module.
