We present the impacts of silicon nitride (SiN x ) antireflection coating refractive index and emitter sheet resistance on potential-induced degradation of the shunting type (PID-s). Previously, it has been shown that the cell becomes more PID-s-susc

Various characterization techniques have historically been developed in order to screen potential induced degradation (PID)-susceptible cells, but those techniques require final solar cells. We present a new characterization technique for screening P

A method to fabricate microelectromechanical systems (MEMS) clamped?clamped resonators using polymethylglutarimide (PMGI) as a sacrificial release layer has been developed. Control of the critical air-gap dimension between the resonator beam and driv

The photovoltaics industry is expected to slowly transition from p-type mono-Si cells to n-type mono-Si over the next several years. Diffusion of boron into silicon to fabricate a p+ emitter can result in an efficiency-reducing boron rich layer (BRL)

We present the development and characterization of n-type mono-Si photovoltaic cells with p+ emitters formed by the rapid thermal annealing of PECVD boron-doped amorphous silicon (a-Si) films. Aluminum metallization was deposited from evaporator and

As crystalline silicon solar cells continue to get thinner, the surfaces of the cell play an ever important role in controlling the cell efficiency. One tool to minimize surface recombination is field effect passivation from the charges present in th

Detailed balance calculations are prevalently used to calculate the thermodynamic limit of performance of photovoltaic devices. This work combines the detailed balance calculations with the lifetime curve to determine the limiting performance of sili

The charged state density at the a-Si/c-Si interface is an important parameter in a heterojunction a cell. The extraction of the charged state density at the interface from measurements of lateral conductance is demonstrated by simulations. In a-Si/c

The high absorption of extreme ultraviolet (EUV) radiation by all materials necessitates the use of thin photoresist films with thicknesses less than 200 nm for EUV lithography to ensure good imaging. Thinning the resist thickness below 150 nm or eve

Hydrogenated silicon nitride films (SiNx:H) deposited using a PECVD process enhance the performance of crystalline silicon solar cells by functioning as an efficient antireflection coating and passivating layer. In this paper, we compared two SiNx:H
