One of the remaining obstacles to achieving the theoretical efficiency limit of crystalline silicon (c-Si) solar cells is high interface recombination loss for minority carriers at the Ohmic contacts. The contact recombination loss of the ultra-thin-

One of the remaining obstacles to approaching the theoretical efficiency limit of crystalline silicon (c-Si) solar cells is the exceedingly high interface recombination loss for minority carriers at the Ohmic contacts. In ultra-thin-film c-Si solar c

In this work, the luminescent coupling (LC) effects on photocurrent-matched and photocurrent-mismatched multijunction solar cells are investigated from fundamental physical theories and modeled by spice circuit simulations. It is demonstrated that th

Nanostructures have been widely used in solar cells due to their extraordinary optical properties. In most nanostructured cells, high short circuit current has been obtained due to enhanced light absorption. However, most of them suffer from lowered

In crystalline silicon (c-Si) solar cells, carrier selective contacts are among the remaining issues to be addressed in order to reach the theoretical efficiency limit. Especially in ultra-thin-film c-Si solar cells with small volumes and higher carr

Although III–V compound semiconductor multi-junction cells show the highest effi ciency among all types of solar cells, their cost is quite high due to expensive substrates, long epitaxial growth and complex balance of system components. To reduce

We propose a programmed syringe pumps system for diffusion-based concentration control in microcavities. Fluorescein is used to demonstrate the influence of different durations of unvarying injecting speed and different sizes of microcavities on the

Nanostructures in III–V solar cells have been widely investigated. Due to the enhancement in photon absorption, higher short-circuit current has been achieved in a number of previous reports. However, many of the nanostructured solar cells suffer f
