The electrical performance of a photovoltaic (PV) silicon solar cell is described by its current–voltage (I–V) characteristic curve, which is in turn determined by device and material properties. In this study, an investigation of the performance and device parameters of photovoltaic single crystalline silicon (Si) solar cell of the construction n+pp++ PESC (Passivatted Emitter Solar Cell) at d...

Insoluble CuMePc nanocrystals were incorporated into P3HT:PCBM bulk heterojunction photovoltaic cells to increase the carrier mobility and photon harvesting. The P1C1-based (weight ratio of P3HT: CuMePc = 1:1) OPV cell exhibited the best photovoltaic performance with a J(SC) of 16.3 mA cm(-2), V(OC) of 0.58 V, FF of 0.56 and PCE of 5.3%.

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...
